Paul,
Gary's post may solve your problem, if not:
Down in the electrical bay (on the '97 Liberty) there is a couple of timed relays that delay the switching of power from shore to generator and battery.As I recall these are in one of the power boxes. These relays simply plug into a socket and are very easy to replace. I had one of the these relays go bad and was unable to switch over from generator to shore power. On the 97 both relays are the same and can be switched to determine if one is bad. Unfortunately I don't have access to the Liberty otherwise I would post a pix. This may not be your issue, but it's one I would certainly check.
Hang in there as it takes a while to work all the bugs out and to figure out what does what. The good news is that with every fix and problem you are expanding your bus knowledge, which will serve you well down the road. We've all been there, except for Lew.
