2. Check The Circuit For A Short
A. Turn the keyswitch OFF.
B. Disconnect the switch from the machine harness.
C. Disconnect the J1 and J2 machine harness connections from the Machine ECM.
C. At the machine harness connector for the ECM, one at a time, measure the resistance between each of the signal contacts to every other contact used in the J1 and J2 machine harness connectors.
The resistance is greater than 5 K Ω. OK - The resistance is correct.
Proceed to Test Step 3.
NOT OK - The resistance check is not correct.
Repair: There is a short in the signal circuits of the machine harness. Repair or replace the machine harness.
STOP
3. Check the Operation of the Switch.
A. The keyswitch remains OFF.
B. Reconnect all harness connectors.
C. Check the operation of the switch. Refer to the table for the suspected faulty switch at the beginning of this procedure for switch operation.
The switch operates correctly. OK - The switch is operating correctly.
Proceed to Test Step 10.
NOT OK - The switch is not operating correctly. The switch has failed
Repair: Replace the switch.
STOP

4. Check the Harness For an Open
A. Turn key start switch and disconnect switch OFF.
B. Disconnect the switch from the machine harness.
C. Disconnect the J1 and J2 machine harness connector.
D. At the machine harness connector for the switch, place a jumper wire between the signal contacts.
E. At the machine harness connect for the ECM, measure the resistance between the signal contacts.
The resistance is less than 5 Ω. OK - The circuit is correct.
Proceed to Test Step 5.
NOT OK - The resistance is
