Jeep 68080460AA Engine Starter

You can Select Your Vehicle to check if 68080460AA fits your vehicle.

Start by checking the battery cables and connections, testing the battery's condition, and examining the starter motor wiring. Check the related fuses and inspect the ignition switch circuit. Verify the operation of the clutch pedal position switch or the TR sensor. If the starter does not activate, check for battery voltage at the starter solenoid. If voltage is present, remove and bench test the starter motor assembly. If the pinion drive extends but does not rotate, the solenoid is operational but the starter motor is defective. If the solenoid plunger extends and rotates the pinion drive, the starter assembly is functioning correctly.

Installation is the reverse of removal for all engine types.

Disconnect the cable from the negative terminal of the battery.

Remove the starter from the engine and bench test the starter. If the starter turns over slowly, check the starter cranking voltage and the current draw from the battery. This test must be performed with the starter assembly on the engine. Crank the engine over (for 10 seconds or less) and observe the battery voltage. It should not drop below 9.6 volts. Also, observe the current draw with an ammeter (Use an inductive ammeter to measure starter current draw). Typically a starter should not exceed 160 amps. If the starter motor amperage draw is excessive, have it tested by a dealer service department or other qualified repair shop.
