Connections for the action alarm | |
The action alarm is connected to power (wire 410-WH) through the instrument cluster. The action alarm is connected to ground through the dash ground (wire 205-BK). When the key start switch is in the ON or START position and the engine is not running, the action alarm will sound.
Test Step 1. CHECK THE INSTRUMENT CLUSTER FOR POWER
- Turn the key start switch and the disconnect switch to the ON position.
- At the harness connector for the instrument cluster, measure the voltage. Measure the voltage from contact 1 (wire 113-RD) to contact 2 (wire 205-BK).
Expected Result:
The voltage that is measured is approximately battery voltage.
Results:
- OK - The voltage that is measured is approximately battery voltage. Proceed to test step 2.
- NOT OK - The voltage that is measured is NOT approximately battery voltage. The fuse for the instrument cluster is blown. Also, the fuse may have popped.
Repair: Check the fuse for the instrument cluster. If the fuse has popped, replace the fuse. If the fuse has failed, replace the fuse.
STOP
Test Step 2. CHECK FOR +BATTERY AT ALARM
- The key start switch and the disconnect switch remain in the ON position.
- At the action alarm, measure the voltage at connector contact 1 (wire 410-WH) to frame ground.
Expected Result:
The voltage is approximately battery voltage.
Results:
- OK - The voltage is correct. Proceed to test step 3.
- NOT OK - The voltage is not correct. Proceed to test step 4.
Test Step 3. CHECK THE ALARM AND THE CIRCUIT TO GROUND
- Turn the disconnect switch and the key start switch to the OFF position.
- Place a jumper wire from connector contact 2 (wire 205-BK) at the harness for the action alarm to connector contact 2 (wire 205-BK) for the harness at the instrument cluster.
- Turn the disconnect switch and the key start switch to the ON position.
Expected Result:
The action alarm sounds.
Results:
- OK - The action alarm sounds. There is an open in the circuit for ground.
Repair: Repair the wiring harness. See the full system schematic for more information.
STOP
- NOT OK - The action alarm does not sound. The alarm has failed.
Repair: Replace the alarm. Make sure that this corrects the problem.
STOP
Test Step 4. CHECK THE RESISTANCE TO THE +BATTERY
- Turn the disconnect switch and the key start switch to the OFF position.
- Insert a multimeter probe to connector contact 23 of the machine harness for the instrument cluster. Insert the other probe to connector contact 1 of the harness for the action alarm.
Expected Result:
The resistance is less than 5.0 ohms.
Results:
- OK - The resistance is less than 5.0 ohms. The wiring harness is correct. The instrument cluster has failed.
Repair: Replace the instrument cluster. Make sure that this corrects the problem.
STOP
- NOT OK - The resistance is greater than 5.0 ohms. An open exists in the wiring harness for power.
Repair: Repair the wiring harness. See the full system schematic for more information.
