Is a starter solenoid the same as the starter relay?


No. Starter solenoid is attached to the starter itself and activates when key turned to start and is used to engage starter drive at starter into flywheel on engine to cause rotation. A relay sends current from ignition to starter solenoid to engage it as required.

Tip

Trouble-shooting your Isuzu starter..


Basic operation of a starter:
Your engine's starter motor is an electrical motor that is used to rotate the engine in order to get it to fire up. This motor draws a large amont of current from the battery (in the order of 70 Amps and up). In order to supply power to the starter a solenoid is used, it acts as a switch between the battery and the starter motor. This solenoid also engages the starter gear with the engine's flywheel and disengages it once the engine is started. Because the circuit for the solenoid also draws a heavy current a further relay is needed to control it.
The diagram below shows the electrical layout of the starting system.
  • i : Battery
  • ii : Starter relay(located in the relay box in the engine compartment)
  • iii : Starter solenoid
  • iv : Starter incorporating solenoid and motor.
  • v : Engine
  • vi : Battery earth cable
  • vii : Engine earth cable
  • viii : Ignition fuse
  • ix : Starter fuse
  • x : Solenoid to starter supply cable
  • xi : Ignition switch
  • xii : Starter motor
When the ignition(xi) is turned it supplies power from the battery through fuse (viii) to the starter relay(ii).
The starter relay activates and supplies power to the starter solenoid(iii) via fuse (ix)
The starter solenoid activates and connects power from the battery to the starter via a short cable(x) between the solenoid and starter motor. This allows the starter motor to turn.

General trouble shooting.
Turn the ignition off.
1/ First you need to check that the fuses are intact.
Keep the ignition off. Place the vehicle in Neutral. Chock the wheels and engage the parking brake.
2/ To prove the starter motor, connect power from the battery positive to the cable (x). This must be done with jumper cables. Touch the jumper cable to the connector on the back of the solenoid where cable (x) connects. Take care not to short circuit the jumper cable to the engine or vehicle body. It can be a tight fit and might not always be possible. If you hear the starter motor spin then it is working along with the engine earth cable. If not, connect the negative lead of the jumper cable between the battery and the starter motor body or any other bare piece of metal on the engine and put the positive lead on cable (x) again. If the starter motor does not spin it needs to come out for repair/replacement. If it spins check both the battery earth cable and engine earth cable and repair where nescasary.
3/ Once the starter motor has been proved move on to the solenoid. Remove the thin wire from the solenoid. Using a small piece of wire, connect battery positive to the connector where you just took off the wire. The solenoid should kick in and the starter motor will turn the engine. If the solenoid does not kick in, remove the starter for repair/replacement of the solenoid. If the solenoid kicks in then replace the starter relay.

If the starting circuit still does not operate the fault will be in the wiring. This needs reasonable expertise and if you dont have a voltmeter handy is not advised.
Bear in mind on automatic transmission vehicles there is an additional switch (Mode switch) wired in between the ignition switch and the starter relay. This switch is on the transmission itself and if faulty will not allow the starter to operate even if steps 1 to 3 were successfull. The same goes for the anti theft/immobiliser system.

The following is specifically for Isuzu Trooper and Rodeo :
  • i : Battery
  • ii : Starter relay(located in the relay fuse box in the engine compartment designated X-17)
  • iii : Starter solenoid
  • iv : Starter incorporating solenoid and motor.
  • v : Engine
  • vi : Battery earth cable
  • vii : Engine earth cable
  • viii : 10A Starter fuse C-1(Fuse box: LH footwell on LHD vehicle, RH dash on RHD vehicle)
  • x : Solenoid to starter supply cable
  • xi : Ignition switch
  • xii : Starter motor
  • xiii : 80A Main fusible link FL-1(Relay fuse box)
  • xiv : 50 A Key SW fusible link FL-2(relay fuse box)
  • xv : Mode switch(A/T only - mounted on the side of the transmission) and for 6 cylinder manual transmission engines this is the clutch start switch mounted on the clutch pedal.
  • xvi : Anti theft system
  • B2 : B2 on ignition sitch
  • ST : ST on ignition switch

#1 Try starting the car in Neutral, if no start replace the Park and Neutral safty switch. #2 Check for a faulty starter solenoid. #3 Check for a faulty stsrter motor. #4 Check for a faulty ignition switch. #5 Check for faulty starter Relays.#6 Check the Transmission Range sensor it could be out of adjustment or defective. #7 On 1998 and later models, the power relay is in the power distribution box in the engine compartment. Refer to your owners manual for more information on relay location. Good Luck From Ernie @ RedDeer, Alberta, Canada.

I have a 2004 Ford Mustang. What does the relay FOAB-14B192-AA control and where is the starter relay.


Engine compartment fuse/relay box
#24 is starter relay (24 is the starter relay)
#31 is low speed cooling fan relay
#29 is fuel pump relay
#25 is A/C Clutch relay
#23 is blower motor relay
#30 is PCM relay (engine computer)

I/P fuse panel


#34 battery saver relay
#35 Driver's unlock relay

When trying to start the car. The starter will not turn over engine it has a new battery all other electirc stuff works. Its like there is no power going to the starter?


First check fuse 13 in the engine compartment fuse box. If that isn't the start relay fuse, also check the #1 fuse inside the car.

Next, is your security light on? If yes, the problem is your anti-theft system probably not recognizing your key.

If fuse is good and no security light, next (assuming you have an automatic trans) try moving the shifter while you hold your foot on the brake and the key in the start position. This is a check on the adjustment of the safety interlock. If this doesn't work, you might also want to try shorting the terminals in the interlock by pulling the connector off and putting a paper clip in the connector terminal and shorting the purple and yellow terminals together. This will tell you if the switch is completely dead.

If none of that works, check the relay in the engine compartment relay box by the battery. Does it click when someone turns the key to start? If not, pull out the relay and interrogate the socket for the command signal from the ignition switch (see my post here on how to interrogate a relay socket: http://www.fixya.com/cars/r6022358-relay_check)
If there is only one hot terminal in the relay socket with the key turned to start, replace the ignition switch. If there are 2 hot terminals, try swapping the relay with the horn relay. If that works, buy a new relay.

If all of the above is good, try jumping the solenoid. (see test 2 in this post: http://www.fixya.com/cars/r6222268-engine_doesnt_crank_turn_over)

If that works you know you have battery and starter for sure. If not, replace the starter.

Let me know if you have any questions at all. :o)

Just changed the stater, however, it will only click when i turn the key, any suggestions


In order to have the starter work, the solenoid has to close the positive connection to the starter. The solenoid now is corroded inside, when it click to engage the contact inside, but the contact is not good to conduct the current to the starter. Therefore your starter is not turning. Need to replace the solenoid. it is on top of your starter. Here is the image. 5cc5b1b.jpg

I have a 1997 f150 that won't start, just clicks. Tested the battery and cleaned the battery posts still nothing.


Check cable for corrosion or signs of heat.Check voltage to starter. Most likley a starter but don't overlook the basics like is the engine seized or is there a loose/bad connector to engine ground.

2002 mercury mountaineer 4.0 starter relay location


The power distribution box is
located in the engine compartment.
The power distribution box contains
high-current fuses that protect your
vehicle’s main electrical systems
from overloads.
The starter relay is in position #56 of that box.
