Circuit/System Verification

Verify that battery is sufficiently charged and that the battery cables are clean and tight.
- If battery not sufficiently charged, refer to BATTERY CHARGING .
- If battery cables are not within specified range, refer to FASTENER TIGHTENING SPECIFICATIONS - ENGINE ELECTRICAL .
Turn the ignition switch to the start position. The starter solenoid should click.
- If starter solenoid does not click, refer to STARTER SOLENOID DOES NOT CLICK .
Remove the drive belt. Refer to DRIVE BELT REPLACEMENT .
Turn the ignition switch to the START position.
- If the engine cranks, inspect the engine and belt drive system for mechanical binding, seized engine, or seized generator, etc.
- If the engine does not crank, refer to ENGINE WILL NOT CRANK - CRANKSHAFT WILL NOT ROTATE .
Using a DMM, measure between the positive battery cable and terminal B at the solenoid as the ignition switch is turned to the START position. Voltage should be less than 0.5 volt.
- If greater than the specified value, replace the positive battery cable.
Using a DMM, measure the negative battery cable to the starter motor case as the ignition switch is turned to the START position. Voltage should be less than 0.5 volt.
- If greater than the specified value, replace the negative battery cable.
If all circuits test normal, replace the starter motor.
