Just a little update. When I went out and switched the wiring back over to shore power I figured out how to get the box off the back of the panel. I had to take out all the ac circuit breakers and also the board that holds the dc fuses. Behind there are two screws that hold the switch box on the back.
I took the screws out and was able to tip the box enough to see inside just a little. Getting it out is going to require removing some wiring. I didn't take it all the way apart because I'm getting ready to go on vacation and don't want to be waiting on parts.
I can barely see the contactor. I can also see what what looks like the connector side of a standard automotive/generic type relay.
I used a screwdriver and checked to see if the contact is welded. It is not, moves freely. I thought it might work after messing with it but no such luck.
When I get back from vacation near the end of October I will take it all the way apart and post what I find.
Thanks
