Explanation

The alternator on the Kubota powerpack is not charging the ECU battery.

Causes

• Faulty alternator
• Faulty wire from alternator to pin 38 on rear ECU.
• Short on wire between water temperature switch and Pin 16 on front ECU.

Operator Actions

• Use override code to continue operation
• Request service

Service Tasks

• If the BLUE wire to the alternator has continuity with earth while the engine is running (i.e. while oil pressure is sensed by the ECU) then the message above will be displayed
• Check the voltage at the alternator and ensure that it reaches at least 14.1V when the engine is running
• Disconnect the spade connector from the alternator and see if the message disappears
• If the message does not disappear check the continuity of the wire between the alternator and Pin 38 on the Rear ECU. There must be no shorts to earth
• Otherwise check directly on the alternator to ensure that the contact floats when the alternator is spinning
