Leaving on a trip tomorrow and went out this AM to start up the coach to position it closer to the house for provisioning. I had not started it for approximately 3-4 weeks prior to trying this morning. When I turned the ignition key on nothing happened. I even tried using the Aux Start but my coach batteries are old and weak. I went out and bought (2) new chassis batteries and (2) new coach batteries and hooked everything up. Went to start coach (300 HP Cummins Diesel) and nothing happened. Tried the Aux Start and it started right up.
The Check Engine light came on with a code of ECU 128 Diag 1 Fault 1. The dash voltage indicator said there was 13.85 V available from the alternator.
I moved the coach and then went back and checked all of my connections on the chassis battery and measured the voltage (12.56 V).
Not sure what else to look for. Any advice would be appreciated.
