Take a wire and jump the two posts on the solenoid or touch the two cables together. If your starter works, then you need a new solenoid. If you hold the starter button and tap on the starter with a plastic hammer and the starter works you need new starter brushes. Anything else wrong with the starter and you need to replace the starter assembly , the manufacturer does not make replacement parts for the starter.

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.

How to wire a relay

We put the new starter on today, and the car still won't start. We are thinking it's the starter relay. What else can be wrong with the car? can you please help us we depend on that car. Thank you


There is no starter relay shown in a wiring diagram. The only thing between the ignition switch and the starter solenoid is the park/neutral switch (or the clutch pedal position switch on manuals).

Do the warning lights and gauges come on with key on? That would verify power is into the switch and being sent out. The small purple wire on the starter solenoid should have power on it when the key is held in start position. If it does, recheck your starter and battery connections. When the purple wire energizes the solenoid, the starter motor should crank the engine.
If no power on the purple wire in start, check the neutral safety switch or the clutch switch if a manual. The start wire out of the ignition switch is a yellow wire, and the wire from either safety switch to the starter solenoid is a purple wire.
(The power to the ignition switch is from the 50 amp Ignition fuse in the under hood fuse block.) See? The positive battery cable is connected to the starter, but not to the starter motor. When the key is in start, the hot purple wire energizes the solenoid and the battery cable is connected to the starter motor.

My dr200 won't start with the starter motor I've taking it out and tested it and it turns over but when it's in the bike and I push the button nothing happens can anyone please help me out cheers


Sounds like the starter solenoid is not transferring electrical power to the starter, or starter relay (if fitted) is not working. Check for a good engine earth. Connect a test light to the starter terminal and an earth, press the button, if it does not light, follow the cable to the solenoid and test for power to the solenoid from the battery, check earth to solenoid body and using the test light check the small wire has power when the button is pushed, if no then you are looking at the relay. Silly question, have you checked the side stand switch, kill switch and neutral switch. These all break the power to the starter solenoid. If you bridge any of these switches, please ensure the bike is in neutral. Good Luck

When I attempt to start te car nothing turns. Have electrical power but the engine doesn't start doesn't even click. Is it my starter?


It can be many reasons but then you must check for the starter motor voltage from the solenoid switch. So if the key switches the starter, the solenoid should receive the voltage , switch on and then supply voltage to the starter.
So if no power to solenoid, check the key switch.
If power comes ot solenoid but no output to starter, then change solenoid switch
However if voltage comes to starter but does not turn then starter coils, brushes are faulty. repair or replace.
Hope this advice helps, credit if helpful.

Ignition has no electicity going to it everything else works and we can start the car by bypassing the ignition is there a fuse somewhere we aren't seeing or a wire or is it the key part does anyone know...


Hi, there should be a fuse and a Starter Relay located in engine compartment, driver side, front side of strut tower, mounted in relay block on fender wall.

Different manufacturers use different abreviations for circuit fuses and relays, I recommend to check all of them.

Also, check if when key is in RUN, power is getting to the Starter Selenoid Mounted on top of the Starter thru the skinny wire (There is a FAT wire coming straight from the battery, that one is HOT at all times,) if power is coming in, REPLACE STARTER SELENOID, if no power present, REPLACE IGNITION SWITCH.

I've includded a troubleshooting chart, instruccions on how to replace STARTER SELENOID and some pictures to help you better identify and fix your problem. (I always think is better to have too much information than not enough) : )

Four types of starter motor are utilized depending upon the vehicle transaxle and assembly plant location. Manual transaxle equipped vehicles utilize a conventional starter motor which consists of a yoke, an armature assembly, an overrunning clutch assembly, a solenoid, a commutator end cover, a brush holder and a pinion drive lever. Automatic transaxle equipped vehicles utilize a reduction type starter motor which has, in addition to the components found on conventional starter motors, a reduction gear and shock absorber assembly.

In the basic circuit, the solenoid windings are energized when the ignition switch is turn to the START position and the clutch start/neutral safety switch is closed. The resulting plunger and shift lever movement causes the pinion to engage the engine flywheel ring gear. This movement also causes the starter solenoid contacts to close
.
With the contacts closed, the starter solenoid provides a closed circuit between the battery positive terminal and the starter motor. Because the starter motor is permanently grounded to the engine block, the circuit is complete and cranking occurs as soon as the starter solenoid contacts are closed.

When the engine starts, the pinion is designed to overrun and protect the armature from excessive speed until the ignition switch is released from the START position. With the ignition switch released, a return spring in the solenoid assembly forces the starter solenoid contacts open, breaks the circuit between the battery and the starter motor, and disengages the pinion. To prevent prolonged overrun, the ignition switch should be immediately released upon engine start-up.

  1. Disconnect the negative battery cable.
  2. Remove the positive battery cable from the starter.
  3. Label and disconnect the solenoid electrical connectors.
  4. Scribe matchmarks on the solenoid and drive housing to ensure proper solenoid installation.
  5. Remove the nut and field coil lead wire from the solenoid.
  6. Remove the screws and solenoid from the starter.

To install:
  1. Lightly grease solenoid plunger.
  2. Install solenoid to starter aligning housing matchmarks.
  3. Install screws and tighten securely.
  4. Install field coil lead wire to solenoid and secure with retaining nut. Tighten to 89 inch lbs.. (10 Nm).
  5. Install the solenoid electrical connector.
  6. Install the positive battery cable. to the starter. Tighten to 89 inch lbs.. (10 Nm).
  7. Connect the negative battery cable.
Let me know how it worked out, Good Luck,

I would suspect the starter solenoid has failed.

A starter solenoid (or starter relay) is the part of an automobile which relays a large electric current to the starter motor, which in turn sets the engine in motion. In many vehicles the solenoid also engages the starter pinion with the ring gear of the engine.

The starter solenoid receives a large electric current from the car battery and a small electric current from the ignition switch. When the ignition switch is turned on, a small electric current is sent to the starter solenoid. This causes the starter solenoid to close a pair of heavy contacts, thus relaying a large electric current to the starter motor, which in turn sets the engine in motion. The starter motor is an electric motor that initiates piston motion in a car's internal combustion engine before it can power itself.

Starter moter??


hi what is it doing? did you try the starter solenoid? and do you have power going to the solenoid and to the starter. jump the big power wire going to the solenoid to the small wire.and check if the starter turns the motor over.it may be the starter relay.or a bad switch.
