Rework Procedure
ONLY replace the batteries and/or starter motor upon failure due to the engine wiring harness connections being incorrect. Follow "Inspection of the Engine Wiring Harness Connections" listed below in order to determine if the connections are correct.
Inspection of the Engine Wiring Harness Connections
1. Start the machine (engine) and let idle for 5 minutes.
2. Turn the key to the "OFF" position.
3. Watch the Monitoring System indicator lights (Image 1.1.1) on the side console to determine if the machine PASSED or FAILED the inspection.
PASSED - If all the indicators lights DO NOT illuminate after turning the machine off.
FAILED - If any of the indicator lights illuminate and flicker out after a few seconds.
