[/mk_fancy_title][vc_column_text css=".vc_custom_1512967728785{margin-bottom: 0px !important;}"]
What is a Starter Solenoid
A starter solenoid is a combination of solenoid and switches (Full proper name: Starter Solenoid Switch). It is one of the main components of the car starter (Motor, Starter Bendix Drive, Starter Solenoid)
As we all know, the starting of the engine requires external support, and the car starter is playing this part. In full general, the starter uses three components to achieve the entire starting procedure.
- The motor receives electric current from the bombardment and make the starter drive gear generate mechanical move;
- The Bendix bulldoze engages the pinion gear into the engine flywheel and disengages automatically after the engine starting time.
- And the starter's on/off part is controlled past the starter solenoid.
Starter Solenoid Functions
Starter Solenoid has two functions:
1. To control the start circuit on / off (Connect the battery to the starter)
2. Bulldoze the starter pinion engaging in the flywheel ring gear.
Office one
When turn on the ignition switch and the starter circuit is turned on, the electric current flows to Starter Solenoid and create the electromagnetic force.
The electromagnetic strength of the solenoid switch sucks the movable fe core in the Starter Solenoid to contact the two terminals, i of which connect to the positive pole of the battery and the other final to the starter.
Role two
The electric electric current divides into 2 streams flowing through the Starter Solenoid:
A ). A stream menstruation through the sucking coil, generating a magnetic strength to sucks the movable fe cadre and move the fork backward then that the starter pinion can engage the engine flywheel.
B). The another stream flows through the holding curlicue, creating a magnetic forcefulness to keep the core in the post-pulling position until the starting complete.
Where is the starter solenoid
In a auto starter motor with Starter Solenoid, the Starter Solenoid is usually mounted direct on the to of starter motor. So where is the starter motor, where is the starter solenoid.
Starter Solenoid Operation
The whole process of starter solenoid switch can be divided into 3 stages: Sucking, holding, render.
(i) Sucking
When the ignition switch turns to the Start position, the bombardment current flows to the sucking curl and hold roll.
The current then flows from the sucking curl to the armature coil thus make the coil rotated at a low speed.
In this way, the movable core of the solenoid switch sucks into the core.
Through the sucking operation, the starter bulldoze pinion will be pushed out and engaged with the ring gear. Also, the contact plate closes the main contact betoken.
(two) Holding
When the chief contact point of the plate close, no current flows through the sucking curlicue. So, the magnetic field coil and the armature coil can go the electric current straight from the battery.
The armature coil then begins to rotate at loftier speed, and the engine starts.
Considering no current flows through the sucking coil, so the moving iron core tin can merely concord the coil in a fixed position by the magnetic force.
(iii) Return
When the ignition switch turns from START to ON, the current flows from the primary contact side to the holding coil via the sucking scroll.
In this betoken, since the magnetic strength formed by the sucking coil and the holding coil neutralize each other, they lose the strength to hold the movable cadre.
Thus, the plunger is pulled back by the return spring force, and the contact plate is asunder, the starter stops.[/vc_column_text][/vc_column][/vc_row][vc_row css=".vc_custom_1498088701961{groundwork-color: #f2f2f2 !of import;}"][vc_column][mk_fancy_title color="#000000″ size="41″ font_weight="900″ margin_top="20″ font_family="Patua+One" font_type="google" align="center"]

[/mk_fancy_title][vc_column_text css=".vc_custom_1532476334345{margin-bottom: 0px !important;}"]
Starter Solenoid Problems
The starter solenoid has four common problems:
1) The suction fails occasionally, or works in engine cooling only and fails in engine warming up.
2) When starting up, the starter solenoid tin can not reset. Release the start push, the starter remains in operation and only stops when power off.
3) The elastic strength of the return spring weakens afterward repeated use, resulting in that the drive gear of one-way clutch cannot exist restored timely, merely driven and reversely dragged by the flywheel ring gear.
four) When the starter starts, it will make a periodic racket from the starter solenoid, just the starter does not rotate.
Symptoms of a bad starter solenoid
A multimeter is needed to exam and verify the problems of the starter solenoid, simply before the testing, the following table can be used to determine whether the starter solenoid works:
[mk_table]
| Error symptom | Possible reasons for the failure |
| The starter solenoid make the clicking noise continuously | The starter solenoid holding coil keep holding or the contacts sealing-off |
| Afterward switching on the starter, the starter solenoid makes the clicking noise, slightly moves only does not rotate. | a.The connection betwixt the solenoid and starter is lacking b.Starter solenoid is broken |
| The offset button has disengaged, and the drive gear has returned, only the starter continues to rotate. | The starter solenoid contact burn-out |
| The start push is disengaged, the starter continues to rotate, only the bulldoze gear can not reverse. | The starter solenoid has contact burnt, or the movable fe core and return jump cannot motility due to no plenty elastic force(poor quality) |
[/mk_table]
Exam a starter solenoid with a multimeter
Set the multimeter dial to continuity mode, connect the multimeter probes to the solenoid terminal post( the i used to connect to the motor body) and the solenoid beat out.
If there is a resistance, then the holding whorl is good.
If the resistance is zip, then the circuit might be shorted.
If the resistance is space, and so the circuit could exist cleaved. If in that location is a short circuit or cleaved circuit, you should replace the starter solenoid.
If your multimeter has the continuity mode, it volition be even easier to figure out your starter solenoid condition by testing the continuity of each connectedness.
Set the continuity way, check the continuity betwixt Terminal S and M. If there is a continuity,(The screen displays a value of nothing (or near zero), and the multimeter beeps. ) replace the solenoid.
Set up the continuity mode, check the continuity between Terminal Due south and the motorcar body. If in that location is no continuity(The screen will display 1 or OL (open up loop).), replace the solenoid.
Prepare the continuity style, check the continuity between Terminal K and B. If in that location is continuity(The screen displays a value of naught (or most aught), and the multimeter beeps. ), supercede the solenoid.
Starter Solenoid No-load Test
one.Starter Solenoid Sucking Curl Exam
Undo the outer lead of the starter field winding (Final C, see Fig. below), connect the positive pole of the car battery to Terminal 50, and negative pole to the starter Terminal C and the shell.
At this point, the drive gear should move forwards.
If not, the solenoid sucking roll is very likely damaged.
2. Starter Solenoid Property Coil Test
If the bulldoze gear in the previous test tin move forward, so disconnect the Terminal C and connect it to the wire of the battery terminal negative, as shown in Figure, the bulldoze gear should remain outside.
If the drive gear reverses, it indicates that the solenoid holding gyre is damaged.
3. Starter Solenoid Spring Test
Based on the higher up test, undo the beat wire continued to the battery last negative, as shown in Figure below.
Normally, when the battery terminal negative is disengaged, the bulldoze gear should reverse chop-chop.
If the drive gear cannot opposite, it indicates that the solenoid return leap is damaged.
Troubleshooting/test a starter solenoid with a screwdriver
A screwdriver can as well be used to test the starter solenoid if you don't have a multimeter.
And information technology also is a quick and easy method to diagnose the solenoid starter solenoid clicking noise problems.
Connect the two terminal posts of the starter solenoid with a screwdriver, if the starter does non rotate, the malfunction lies in the starter. If the starter functions well, the malfunction lies in the solenoid switch and is often caused past the ablation of the starter solenoid contacts.
As well, you can endeavour to shake the connecting line of the car battery and the starter, if the starter functions well, then the starting excursion might be in a poor contact. If so, you should check the high temperature or the sparking parts in the starting system circuit.
Bypass Starter Solenoid: Get-go auto with a bad starter solenoid
Sometimes the starter could not rotate, or the rotate speed is low later on switch on (effulgence of the headlamp is fine), and when the starter stop to rotate, there is foreign chugging racket near the starter motor, information technology indicated that the starter solenoid switch got a problem.
If the solenoid switch got some issues when you are driving, y'all could utilize a lead wire to make an emergency starting excursion.
Simply connect the battery terminal anode and terminal B of the starter past a lead wire.
Later the circuit is well connected, turn the ignition switch to commencement position, the starter would piece of work and start the machine engine.
Remember to disconnect the wire immediately once the car starts, and discover the closest repair shop every bit soon as possible to fix the starter solenoid trouble.[/vc_column_text][/vc_column][/vc_row][vc_row css=".vc_custom_1500084984306{background-color: #ffffff !important;}"][vc_column][mk_fancy_title color="#000000″ size="41″ font_weight="900″ margin_top="20″ font_family="Patua+One" font_type="google" align="centre"]

[/mk_fancy_title][vc_column_text css=".vc_custom_1513217848962{margin-lesser: 0px !important;}"]
Starting Organisation Wiring Diagram
Firstly, let's check the of the starting organisation circuit, the wiring diagram as shown in the Fig. below. There is a connexion between the starter, the car battery, and the ignition switch. The working circuit of the starter can be activated afterwards the ignition switch is on.
The starting organization wiring diagram is every bit shown in below paradigm.
While the ignition switch is not turned to the start position, the starter solenoid will not connect to the start circuit, and the starting gear is separated from the flywheel. Once the ignition switch is turned to the start position, the magnetic ringlet circuit will connect to the circuitry.
The sucking coil circuit is as below:
Car battery anode (+) > fuse > ignition switch (start position) > solenoid terminal fifty > sucking roll > terminal c of the solenoid switch > field coil > positive brush > armature coil > negative brush > footing wire > storage battery cathode(-)
The property coil circuit is as below:
Storage battery anode > fuse > ignition switch (start position) > solenoid terminal 50 > holding coil >ground wire > motorcar battery cathode (-)
After current passes through the sucking roll and holding gyre, as the current direction is identical, the magnetic field is superimposed, the iron core will exist sucked in.
Then, the iron cadre volition drive the starter drive clutch to motility astern so that the starter gear can mesh with the engine flywheel.
While the starter gear almost completes the meshing (with the flywheel), the iron core will motion forward to a detail position, to make the contact panel impact with the contacts. Thus the starter solenoid switch will turn on.
After the starter gear has completely meshed with the flywheel, the fe core volition move forrad to an extreme position, and the solenoid switch will be pressed tightly and connect to the car starter. In the stop, the starter motor rotates, and the engine starts driven past starter drive.
The starter motor circuit is equally below:
car battery anode(+) > solenoid switch terminal 30 > contact panel > solenoid switch terminal C > field ringlet > positive brush > armature coil > negative brush > basis wire > car bombardment cathode(-)
When the terminal 30 & C of starter motor are continued, the pull-in coil volition brusk out. The position of the atomic number 26 core after suction tin can be maintained but by the magnetic force of the property coil.
When the ignition switch turns back to On position later cranking the engine, the starting circuit will plow off, and the starter will stop rotating. The starter drive gear returns past the bound, the starter drive gear, will split with the engine flywheel.
Starter Solenoid Wiring Diagram
Not every car carry the starter relay in starting system, and the starter solenoid wiring diagram can be learned by with or without starter relay type.
1. Starter Solenoid Wiring Diagram – Without Starting Relay Type
The starting system excursion without starter relay prepare in is shown in Fig. below.
After turn on the ignition switch, terminal 50 of the ignition switch is connected to the B8 node of the central circuit lath via the reddish or blackness wiring, and then to the solenoid terminal 50 of the starter via the C18 node of the fundamental circuit lath. The bombardment anode (+) is continued to terminal 30 of the starter via the black wiring.
When turning the ignition switch to the showtime position, the current direction is as below:
Car battery anode(+), ignition switch beginning gear, terminal 50, sucking coil, terminal C, field winding, armature winding, ground wire, motorcar battery cathode(-)
Meanwhile, the current direction that passes through the property roll is every bit below:
car bombardment anode(+), ignition switch start gear, terminal l, holding roll, bonding, auto battery cathode. (The working process has been introduced before in Starting Arrangement Wiring Diagram)
ii. Starter Solenoid Wiring Diagram – Without Starter Relay Type
To protect the ignition switch, lots of modern cars apply the starter relay to control the starter solenoid. The starter solenoid wiring diagram with starter relay shows in the following Fig.
When the ignition switch has not turned to the start gear, no electric current will passes through the relay coil, and the starter relay contacts are open up. Also, the starter solenoid is not energized, and the bulldoze gear is separated from the flywheel band gear.
Subsequently turning the ignition switch to the start position, the circuit of the starter relay coil will be conductive, and the electric current direction is as beneath:
After turning the ignition switch to the start position, the circuit of the starter relay coil volition be conductive, and the electric electric current direction is every bit below: machine bombardment anode > ignition switch terminal 1 > ignition switch terminal three > starter relay terminal (The i utilize to connect to ignition switch) > coil basis wire > car bombardment cathode.
After the starter solenoid ringlet is conductive, the starter relay contacts will be closed, and connect to the sucking roll and holding coil excursion. (The working procedure has been introduced before in Starting Arrangement Wiring Diagram)
In the starting system with an electronic-controlled engine, the footing final of the starter relay coil is connected to the neutral position of the ignition switch (cars with automatic transmission can merely first the engine in the position P & Northward ) or the interlock switch of the clutch, every bit shown in the left Fig.[/vc_column_text][vc_column_text]
Starter Solenoid Wiring
How to wire a starter
Most of the solenoids are installed directly on the starter, and they are closely related to each other. Hence, before learning how to wire a starter solenoid, the starter'south wiring should be studied.
A iv-final starter has two thick terminals and 2 thin ones, information technology might be a little confused to find out which is which if you are not a professional.
The 2 thick terminals post
I of the 2 thick terminals posts is continued to the car battery, and the other is connected to the field winding inside the starter via the conducting plate on the vanquish of the starter.
Therefore, the thick concluding mail with conducting plate shall exist connected to the field winding, while thick terminal post without conducting plate shall be connected to the auto bombardment.
But if the conducting plate is non there, how to distinguish between the two thick terminals, then?
Actually, the sucking curl inside the starter solenoid switch is continued to one of the thick terminals via the welding spot, and so to the field winding, the armature winding and finally to the negative brush bonding. Therefore, the thick last with one thread terminate should be continued to the field winding, while thick terminal without thread end should be connected to the auto battery.
The 2 thin terminals mail
The terminal post with 2 thread ends (the sucking coil and belongings coil are welded together via the welding spot and and so connected to the sparse last) is pull-in final, (namely, the solenoid terminal)
The other thin terminal mail service is directly connected to the shrapnel inside the motor, then thin terminal without thread end is the ignition switch final.
How to wire a starter solenoid
In that location are three terminals on the solenoid insulating encompass (besides called starter solenoid cap), those are, last B (or thirty), terminal M (or C) and start terminal S (or fifty).
Sometimes, at that place are 4 terminals on the solenoid cap, and those are: terminal B (or 30), terminal Grand (or C), get-go terminal Due south (or 50) and ignition concluding R (or 15a), as shown in Fig below.
Final B and Terminal Chiliad are normally copper bolts with a thickness of 8mm or 10mm, the i with lug plate is concluding K, which is the ability supply final of the motor field winding; the other one is last 8, which is the ability line final of the car bombardment.
Start terminal S and ignition concluding R are usually atomic number 26 bolts with a thickness of 4mm or 5mm, the 1 with lug plate is starting terminal Due south, the electric wire of which is led to the starter relay; the other one is ignition final R, the electric wire of which is led to the additional resistance of the ignition coil. The solenoid shell is also an invisible terminal 31(the basis wire).
The switch part of starter solenoid is equanimous of a principal contact plate and contacts. The main contact plate is fixed to the front end of the movable iron core button rod, and the two contacts are respectively integrated with the double-screw commodities of the connecting pb terminal C and the power supply last 30.
Nearly the switch contacts, there is an additional resistance brusque circuit switch made of a minor copper sheet, which is connected to the final 15a.
The inner structure of the solenoid is shown in the left Fig.[/vc_column_text][/vc_column][/vc_row][vc_row css=".vc_custom_1500084993763{background-color: #f2f2f2 !of import;}"][vc_column][mk_fancy_title color="#000000″ size="41″ font_weight="900″ margin_top="20″ font_family="Patua+I" font_type="google" align="center"]

[/mk_fancy_title][vc_column_text css=".vc_custom_1512967499990{margin-bottom: 0px !of import;}"]
Starter Solenoid Replacement
If you want to replace your starter solenoid, you have to take out the starter motor from your vehicle showtime. The location of the starter motor can be differed by motorcar models, the post-obit instruction is the regular manner to replace a starter solenoid. The step ane-7 is about removing a starter motor and pace 8-11 most supervene upon a starter solenoid.
Pace 1. Disconnect the auto bombardment negative cablevision
Pace 2. Lift the vehicle if the starter motor is under the car.
Pace iii. Remove the nut in the starter solenoid concluding.
Step four. Dismount the concluding of the cable of the car battery anode from the starter.
Step 5. Remove the nut in the starter solenoid concluding S.
Stride six. Remove the retaining bolts in the starter.
Pace seven. Accept out the starter.
Step 8. Unscrew the retaining nut of the solenoid last, as shown in the pictures below.
Step 9. Unscrew the two nuts that fix the solenoid to the vanquish of the starter Bendix drive and remove the solenoid. As shown in the post-obit picture show.
Footstep 10. Install the new starter solenoid according to the opposite procedure of removing the solenoid.
As shown in the above effigy, hook the plunger hook to the starter fork, then use retaining bolts to install the starter solenoid to the starter trounce. Note and mark the installation direction of the starter solenoid before the disassembly, if install in the opposite position, the starter volition not operate. Connect the motor atomic number 82, install and prepare with a nut.
Stride eleven. Starter Solenoid Retesting
After the solenoid is installed, connect the corresponding circuit. The no-load test can be carried out on the machine battery to verify the maintenance effect of the starter. The starter can be installed on the vehicle after it operates well in the no-load test. The retest way is every bit aforementioned as the Starter Solenoid No-load Test in Chapter ii.
Pace 12. Install the starter motor according to the reverse procedure of removing the starter motor (Step 7-1).
Circumspection: v Tips for replacing a starter solenoid
i. If you lose the retaining bolt of the starter, you should be conscientious with the length of the new commodities, in case that over-long bolt bursts the gyre one-time (some models of solenoids will non have this fault) and induces ground loop. As well, recall to utilize a spring washer when installing the bolt.
two. The electric current of the starter is large in operating and concluding B and last M volition overheat because of that. So call back to use a spanner to tighten the terminal nuts while you are maintaining your starter solenoid.
3. To avoid the bad contact, the lead wire of the concluding B and terminal Chiliad should be clamped with two flat washers.
4. The two retaining bolts in the solenoid embrace contacts are quite like shooting fish in a barrel to loose due to the starter vibrating, so they should be tightened whenever maintaining the starter.
five. To reduce the resistance of the movable atomic number 26 core at work, a thin layer of engine oil should exist coated on the surface of the core (anti-freezing engine oil should be used in winter).
Starter Solenoid Price
The starter solenoid prices are differed by different models, quality, and manufacturers. Meanwhile, larger solenoids (such as the Heavy Duty series starter solenoid) tend to exist more than expensive than smaller ones.
The best is definitely the OEM starter solenoid, and solenoids in the aftermarket are relatively cheaper.
When I was writing this guide, I establish a quite interesting volume, and at that place are many electrical accessories' prices recorded in the volume. Office of the starter solenoid prices are equally follows:

Chapter 5: How to repair a starter solenoid
[/mk_fancy_title][vc_column_text css=".vc_custom_1512967612006{margin-bottom: 0px !of import;}"]Almost of the cleaved starter solenoid switches are repairable, but the labor charge of repairing a solenoid switch tends to be higher than the solenoid switch itself, the repair shops are reluctant to repair the switches, instead of direct replacement is adopted.
Nosotros do not recommend non-professionals repair the switches past themselves. The following content is for reference but to those with certain experience. Non-professionals shall seek aid from the local mechanic.
Starter Solenoid Disassemble
1.Pull out the movable fe core and spring from the rear terminate.
2.Seal off the soldering can at the connection strap of the solenoid box with soldering iron, and so that the solenoid coil joint can trip out.
3.Unscrew the two retaining bolts of the switch cap, separate the starter solenoid cap from the solenoid housing, and pull the solenoid axle assembly parts out from the housing(solenoid shell).
Bones Starter Solenoid Repair
1. Starter Solenoid Stuck Issue
The movable atomic number 26 core should be able to move smoothly. If not, you lot should find the problem(s) that crusade the stuck and fix it. Supervene upon the spring if it'south not in skilful condition. In most cases, the stuck issue is caused by the bad leap.
2. Starter Solenoid Contacts & Contact Plate burn-out
If the solenoid contacts are not burn-out very severely, then simply apply the sandpaper to polish the surface of the solenoid contacts & contact plate.
If the surface is burn-out severity, you should open the solenoid cap, take out the contacts & contact plate, and file the contacts or add the apartment washer(s) till two contacts are in same meridian.(The heights of the two contacts in the switch cap should be consistent)
3. Thread damage of B/M terminal bolts
The terminals usually prefer M8 or M10 copper bolts. The traditional repair method is to dismantle the starter and starter solenoid from the vehicle, detach the solenoid, unscrew the terminal bolt, and employ the threading dice to rethread the terminal bolts.
Starter Solenoid Avant-garde Examination
1.Starter solenoid whorl inspection:
Use the R1(Resistance) scale of the multimeter to measure the resistance of the pull-in coil and the holding ringlet of the solenoid, and the resistance value shall be aforementioned with the starter solenoid specification.
If the resistance R=∞, the curl is disconnected.
If the resistance is lower than the specified value, the scroll has a error of plow-to-plow brusk circuit.
(2) Starter Solenoid Working Performance Inspection:
a. Inspection of pull-in and driblet-abroad voltage of solenoid: When inspecting, deport out wiring according to the circuit shown in the right Effigy.
Firstly turn on the switch, gradually increase the voltage, when the multimeter (resistance calibration) indicates a resistance of goose egg, the indicated value of voltmeter V is the pull-in voltage of the switch.
And so gradually reduce the voltage indicated value, when the multimeter indicates a resistance of infinite, the indicated value of the voltmeter is the dropout voltage of the switch.
The pull-in voltage shall not exceed 75% of the nominal voltage, and the dropout voltage shall non exceed 40% of the nominal voltage.
b. The ignition gyre boosted resistance short-circuit switch inspection:
The testing excursion for the short-circuit switch is shown in Fig.ii-28. When turning on the switch, the indicator light in the circuit should be brightened upward.
c. Starter Solenoid Outage performance Inspection:
When the starter drive gear is stationary and stays in the engaged position, cut off the solenoid power supply. At this fourth dimension, the main contact of the solenoid shall exist able to be interrupted apace.
Based on the inspections higher up, solenoids with poor or unqualified performance should be repaired or replaced.
Starter Solenoid Scroll Rewinding
(1) Seal off the soldering can on the connexion strap of the switch cap and remove the switch cap.
(2) Clench the switch housing on the demote screw, unclench the riveting edge of the switch with a screwdriver, and take out the coil assembly.
(three) Dismantle the burned-out coil (if y'all practise not have the specific information, you should record the coil diameters, the number of turns and winding direction of the sometime ringlet conductor).
Check the coil frame and the insulating pressing plate; if there is damage, you should repair it according to the original shape.
(4) When rewinding the coil, the diameter, the number of turns and the winding direction of the wire should be identical to the original ones.
In general, the holding roll (thin) is in the inner layer, and the pull-in coil (thick) is in the outer layer, the two coils have the same winding direction, and fish newspaper should be used to split up the coils and to carve up the curl frame and the housing.
(v) The positions of the four outgoing thread end on the two coils shall be distributed every bit the correct figure(a).
Insulation tube shall be sheathed on the ends to prevent the insulation varnish of the wires from wearing out.
(6) Put the felt, roll assembly and iron plate in the switch housing and rivet them properly. Then twist the ends 1 and two of the two coils together, and weld starting cease 4 of the thin coil on the iron plate (run across right image b).
(7) Assembling the contact plate and the switch cap, put out the stop 1 and 2 of the coils from the connection strap hole of the solenoid terminal and weld firmly. Pulling out the starting end 3 of the thick scroll from the strap hole of the fixed contact plate and weld firmly (see right prototype c).
In the end, recollect to retest the starter solenoid subsequently fixing starter solenoid.(Refer to Chapter two)[/vc_column_text][/vc_column][/vc_row][vc_row css=".vc_custom_1498096012414{groundwork-color: #f2f2f2 !of import;}"][vc_column][vc_column_text css=".vc_custom_1513217365415{margin-bottom: 0px !important;}"]We're at present at the terminate of The Definitive Guide of Starter Solenoid.
