Last year at Maxton, as many of you might know, my '97 BMC 40' was involved in a polarity reversal at the alternator The coach went back to the Birdsnest for three months of cabling and Inverter re-build, etc.

I shouldn't be surprised to find that the "new" wire harness that was charged for, was never installed. There were many bare wires in the harness and some clipped and bypassed. Detroit Diesel has been here for three days sorting out the mess.

The issue they came to fix, before knowing about my melted harness, was extreme fluctuations in voltage in both the engine and coach voltage. After rebuilding the alternator (again), the chassis voltage is solid. The needle doesn't shake a bit.The coach voltageneedle varies by .5 to 1 volt down from the chassis voltage. I would call it a flicker. When the main battery switch is off, it reads the same as the chassis.

The inverter is not showing any error messages. What is meant on the main shut-off switch by battery 1 and battery 2 and both. Is this isolating the charging/supply from, the chassis or house batteries?

Detroit Diesel is returning tomorrow morning to load test the house batteries. Any suggestions would be appreciated.

Sorry we couldn't be at Maxton. We are having an Air Conditioner installed tomorrow in our new house in Palm City, Florida. We closed last Friday and the AC closed on Sunday!

Look forward to your responses.
