I have a diesel Case 680L backhoe that has an electrical gremlin. The problem is that the machine will randomly shut off and/or won't start when the voltage gauge drops to or reads 0.

The batteries are new and there is still power up to the main electrical connectors in the floorboard of the machine. Also, the standard silver 2 pin metal relays and black plastic square relays under the dash have already been replaced.

Does anyone familiar with these machines know if there is another stash of relays or circuit breakers under the dash that may cause this problem?

Thanks in advance, Mike

P.S. The backhoe will run just fine and all lights will work if I just hotwire the fuel pump solenoid.
