Circuit/System Verification

Ignition OFF, measure and record the battery voltage at the C1 battery terminals. The voltage should be between 12.0 - 15.0 V.
- If not within the specified range, refer to Battery Charging .
Test for less than 0.5 V between the positive battery cable and terminal A X2 at the M64 starter motor as the ignition is placed to the CRANK position.
- If greater than the specified value, replace the positive battery cable.
Test for less than 0.5 V between the negative battery cable and the M64 starter motor case as the ignition switch is placed to the CRANK position.
- If greater than the specified value, replace the negative battery cable.
Remove the drive belts. Refer to Drive Belt Replacement for the 1.5L engine
Place the ignition to the CRANK position. verify the engine does not crank normal.
- If the engine cranks normal, inspect the engine and belt drive system for mechanical binding, seized generator etc.
If all circuits test normal, replace the M64 starter motor.
