    second ignition fuse has burned out. What is causing this?

    My 1998 Chevy Cavalier has blown out multiple ignition fuses. I would like to know what is wrong.

    The same thing was happening to me this winter. I went to inspect and found the heat shield was loose. I think it was touching the two leads on the solenoid and was therefore shorting out. I moved the shield over and have not had a problem since

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

Possible ignition switch. Try gently rocking the key back and forth in the ignition cylinder with the vehicle running without turning the vehicle off. While performing this procedure, try working the windows or have the headlight in the on position to see if it corrects the problem. If the accessories start working,suspect an ignition switch

My 2003 chevytrailblazer motor did roll over but now it dont


Check Battery, if you try to charge or jump starter you may hear a click. If you're sure its a good charged battery then consider starter. Try to jump starter by passing switch, cross small wire to larger wire on starter (you may get sparks) (please be careful if you try this) this should make the starter spin & kick in turning the engine. If it only spins then its probably the starter solenoid. If this checks out then check ignition switch & harness connections. That's it..

I can hear the fuel pump running, lights are on, but won't start the car.


First make sure you have good battery connections. A poor connection will give enough power to turn on head lights but not turn on starter motor. Clean the connections and ensure they are tightened.

If connections are good, check voltage of battery. It should be at least 12 volts.

If battery voltage is low, either charge the battery, or attempt to jump start the car (red to positive terminals, black to negative terminals; attached positive first, prefer to attach negative terminal to a good metal location other than the negative terminal on the battery).

If the starter motor is visible, try tapping lightly with a mallet to free it up. This may or may not work depending on the problem. If the car starts, replace the starter motor anyway or it will strand you again.

Most cars have a starter relay and a fuse for the ignition. Do a Google search on the internet for your model of car, or look in your owners manual to find the location of the solenoid and/or fuse. Replace the fuse if it's burned out. Note that a shorted starter motor could cause the fuse to burn out, so replacing the fuse may not fix the problem. Suspect a shorted starter motor or wire if the fuse burns out again. You may need some professional assistance at this point to check the solenoid.

If the solenoid is bad, it is usually replaced along with the starter. Remove starter motor/solenoid and take to an Autozone or Oreilly or equivalent and have them check its functionality. Be sure to disconnect the battery's negative terminal before removing the starter motor.

If the starter is good, then your problem is likely either your car's security system (check if security light is flashing if you have such) or check the ignition switch. If you have a mechanic friend, see if he can bypass the ignition switch and get the starter motor to turn over.

Poor electrical connections or a bad battery or a bad starter motor/solenoid are the most likely culprits.

The starter will not turn. When the ignition is engaged, I hear the fuel pump run, the lights come on as usual but there is no sound from the starter or the engine. I replaced the starter, but still have...


The problem sounds electrical and one of several problems it could be. Here are the possibilities:
Starter Relay - Switch the starter and AC relays, these are the same relay type doing different jobs
Alarm Starter inhibitor - If you have an alarm installed, cut the main power wire to the alarm
Voltage Regulator - Try jumping the vehicle, if it jumps test the battery if it doesn't replace the battery if the problem persist after replacing the battery remove the alternator and test it
Dead Cell in battery - Try to jump the battery, if it starts then replace the battery
Blown 80 amp in-line fuse - This is usually a small bump looking fuse, you can by pass this but first test for continuity by using a multimeter and connect on each side of the fuse.
grounded positive cable - If a cable has been running close to the frame or engine it may have worn a spot through the insulation and maybe grounding and that will interfere with the starting.

Replaced A 60am Fuse ,Ran For Two Days. Car Died and now i have no electrial juice to the whole car. suspect fuseable link.


You may be correct about the fusible link. Replacing a blown fuse without finding and repairing the reason it blew only leads to more problems and possible severe damage to wiring harnesses. Fuses are NEVER the CAUSE of an electrical problem. Blown fuses are ALWAYS the RESULT of an electrical problem. I would recommend taking the vehicle to someone who has access to the wiring diagrams and the proper equipment necessary to repair your electrical system. A blown 60 Amp fuse is nothing to play with. That fuse gave up it's life to stop your vehicle from burning to the ground. Please don't make it die in vain...car fires are never pretty!

When I turn the ignition key I get nothing from the engine, is this a problem with the ignition switch or the solenoid?


i would not rule out the starter-your best bet to eliminate the starter is to have someone bang on the starter as you turn the key to start it-if it starts great get the starter replaced-it is locking up-if it starts smoking or you smell something burning
that too is a bad starter-replace it
if neither of these work then have someone check the ignition(as long as its not the battery-just cause it has power doesnt mean the battery is not bad-it may not have enough power to start the vehicle)

Yes they do but I would rather think you have a bad battery cabe connection to the system, sometimes the battery cable corrudes and you can't see it try replacing the cable ends and the connector ends espically if they are by the battery.
