Disconnected shore power and let the batteries sit for about 45 min. I took a reading with the DVM and it read 12.8. Turned all the ceiling lights on and took a reading and got a 12.6.
I then reconnected the shore power with all the ceiling lights still on. I went back in the coach and the panel showed 14.5 for battery volts, bulk charging light flashing yellow, and a high battery error.
I shut off all the lights and I still got the flashing bulk charge light, the 14.5 battery volt light, but the error was battery over load.
I went back outside and disconnected and reconnected the shore power and every thing went back to the normal 13.5 and a float charge.
clearly I reset something.
one other thing, I found the battery temp sensor in the battery compartment. It was melted a little. I think it fell off and was dangling near the exhaust.
