Disconnect connector C008. Check for short circuit in the Front Main harness to chassis ground from C008-A or alternator "R" terminal. Expected Result: There is a short in the circuit.
YES, locate and repair short circuit in the Front Main harness. Check fault code and if no longer active the repair is complete.
NO, go to Step 3.
Check for short circuit in the Rear Main harness to chassis ground from C002-28. Expected Result: There is a short in the circuit.
YES, locate and repair short circuit in the Rear Main harness. Check fault code and if no longer active the repair is complete.
NO, go to Step 4.
Test the alternator field output while engine is running by measuring voltage from the terminal on the alternator marked R (wire- FM6) to chassis ground. Expected Result: The voltage measures between 6 and 7 DCV.
YES, go to Step 5.
NO, replace alternator. Check fault codes. If fault code is not
