I will try to make this short. Very weird problem so let me try to explain. Happened about six months ago and just happened again tonight. I have a surge protector in the AV cabinet at the front of the coach. It is plugged into AC outlet in the cabinet. Have TV, Sat Receiver, DVD Player, etc. plugged into the surge protector. I was watching TV tonight and all of a sudden the TV turns off and I smell that funny burned plastic smell. Since this happened six months or so ago, I knew exactly what it was. Surge Protector blown again. There was no power surge or at least loss of AC power that I can tell. Everything else in the coach continued to operate. I did notice a louder humming from the Inverter/Converter and the interior lights dimmed and then got bright. I have a spare surge protector and hooked it up and everything is running fine. My inverter is turned off so it should not have tried to come on even if we had an AC power loss. The outlet where the surge protector continues to blow is an outlet that is powered by the inverter and it has me thinking for some reason the inverter is sending power there while we still have AC power causing an overload. Why this would happen, I don't know, but it just seems tied to the inverter somehow. Also when this happened I went to check the inverter digital panel in the kitchen and noticed it showed it was momentarily pumping 50 plus amps to the batteries for some reason. It quickly went down to 10 amps which is where it normally is if we have a few lights on. Sometimes it goes down to 5 amps with hardly any 12V draw. I hope I am giving enough information and this is making sense. Does anyone have a clue as to what could be happening here? No blown breakers, fuses, etc. Just simply replace the surge protector and everything is fine. I guess it could be a coincidence, but I don't think so. I am concerned this is evidence of something bigger lurking. Thanks for any help.
