Troubleshooting Test Steps Values Results
1. Identify Active FMI Code Associated With The System Voltage Circuit Code present FMI 2 diagnostic code, proceed to Test Step 2.
FMI 3 diagnostic code, proceed to Test Step 7.
FMI 4 diagnostic code, proceed to Test Step 9.

2. Check The Supply Circuits
A. Turn key start switch and disconnect switch OFF.
B. Disconnect the machine harness connector from the ECM.
C. At the machine harness connector of the ECM, measure the resistance between the unswitched supply voltage with the each of the positive contacts of the battery.
D. At the machine harness connector of the ECM, measure the resistance between the switched supply voltage to the contacts of the keyswitch.
Each resistance measurement is less than 5Ω. OK - Each resistance measurement is less than 5 Ω. The supply circuit is correct.
Proceed to Test Step 3.
NOT OK - One or more of the resistance measurements is greater than 5 Ω. There is an open circuit or a poor connection in the supply circuit
Repair:Repair or replace the machine harness.
Proceed to Test Step 11.
3. Check The Ground Circuits
A. Turn key start switch and disconnect switch OFF.
B. Disconnect the machine harness connector from the ECM.
C. At the machine harness connector for the ECM, measure the resistance between each of the negative battery contacts and frame ground.
Each resistance measurement is less than 5Ω. OK - Each resistance measurement is less than 5 Ω. The supply circuit is correct.
Proceed to Test Step 4.
NOT OK - One or more of the resistance measurements is greater than 5 Ω. There is an open circuit or a poor connection in the supply circuit
Repair:Repair or replace the machine harness.
Proceed to Test Step 11.
4. Check The Current Output Of The Alternator
A. Partially discharge the batteries. Perform one of the following:
a. Crank the engine for approximately 30 seconds without starting the engine.
b. Turn on the lights. Leave the lights on about 10 minutes with the engine in OFF.
B. Turn key start switch and disconnect switch OFF.
C. Connect one multimeter probe to positive (+) terminal of the alternator and connect one multimeter probe to the case of the alternator.
D. Connect a clamp on an AC/DC Clamp-on Ammeter or an equivalent ammeter around the output wire.
E. Turn the disconnect switch and the key start switch to the ON position.
F. Start the engine.
G. Run the engine at approximately half throttle.
H. Immediately check the output current of the alternator.
The output current of the alternator at half throttle is approximately 40 - 50 amp. The full current output rating of the alternator is approximately 95 amp. OK - The measurements for the output current are correct.
Proceed to Test Step 5.
NOT OK - The current output of the alternator is not correct.
Repair:Repair or replace the alternator. Refer to Troubleshooting, REHS0354 for detailed instructions on troubleshooting the charging system components.
Proceed to Test Step 11.
5. Check The Voltage Output Of The Alternator
A. The multimeter and the ammeter are still connected. The engine is running.
B. Run the engine for approximately 10 minutes
