FMI 3 Troubleshooting
Troubleshooting Test Steps Values Results
1. Check The Harness For An Open
A. Turn the key start switch and the disconnect switch to the OFF position.
B. Disconnect the machine harness connector from the switch.
C. Disconnect the machine harness connectors from the ECM.
D. At the harness connector for the switch, place a jumper wire between the normally open (N/O) contact and the normally closed (N/C) contact.
E. At machine harness connector for ECM, measure the resistance between the normally open (N/O) contact and the normally closed (N/C) contact.
The resistance is less than 5 Ω. OK - The resistance is less than 5 Ω. The (N/O) and (N/C) circuits are not open in the machine harness.
Proceed to Test Step 2.
NOT OK - The resistance reading for the (N/O) and (N/C) circuits greater than 5K Ω. There is an open in one of the circuits.
Note: A resistance that is greater than 5 Ω but less than 5K Ω would indicate a loose connection or a corroded connection in the circuit. A resistance measurement that is greater than 5K Ω would indicate an open in the circuit.
Repair: Repair or replace the machine harness.
Proceed to Test Step 5.
2. Check The Circuit For A Short
A. The harness connectors for the switch and ECM remain disconnected.
B. Remove the jumper wire that was installed in the previous test step.
C. At the ECM machine harness connector, measure the resistance between the (N/O) contact and all the other contacts used in the ECM.
D. At the ECM machine harness connector, measure the resistance between the (N/C) contact and all the other contacts used in the ECM.
The resistance measurements are greater than 5K Ω. OK - The resistance measurements are greater than 5K Ω.
Proceed to Test Step 3.
NOT OK - The resistance is less than 5K Ω. There is a short between the signal circuit and the circuit with the low-resistance measurement.
Note: A resistance that is greater than 5 Ω but less than 5K Ω would indicate a loose connection or a corroded connection in the circuit. A resistance measurement that is greater than 5K Ω would indicate an open in the circuit.
Repair: Repair or replace the machine harness.
Proceed to Test Step 5.
3. Check The Switch Ground Circuit
A. The key start switch and disconnect switch remain in the
