On your previous problem, what was the relay or fuse that you replaced? what did that go to? when you checked the voltage of your chassis batteries, did you also do it with the engine running? the 110 volt cord that was melted, was that power into the inverter or power out? I think I would have to start with a lot of voltage reading, chassis batteries, engine offf and running, also while pluged into shore power then also with the inverter on, check the house batteries the same way, every combination you can think of, just because they shouldnt be tied together doesn't mean they are.You had a problem with the coach running, That was electrical, then while running it seems your electriacal system was being dragged down, both of those chassis related, then your inverter smoked, coach related,and they should be two different systems, are you using your generator on any of this? also check the voltage of an outlet with the inverter on, check voltage of inverter, shore power and generator
