Trouble with electrical system

I do have the delay in the system. The smoke was more like a puff, but enough that my wife who was standing behind me noticed it along with a loud pop. We purchased the 2005 cross country 372DS by coachman 3 weeks earlier. In preparation for our upcoming trip I was checking all electrical systems,shore power, geni and coach battery. As I mentioned earlier and to my surprise, everything still works. My only suspicion is that the dealer, when cleaning the coach for resale, used a pressure washer and something like "Armor All" every where including the storage compartment where the inverter is located. It's really sticky and shiney, but clean :-). I know the water would have evaporated but possibly the "Armor All" treatment collected on the circuit breaker and momentarily shorted out. Just a theory.

Doesn't sound like everything is alright - smoke came out of the inverter...

I have a transfer relay wired into my inverter/shore/load so the inverter is never connected to shore power, is your inverter wired this way?

Hello. If that was my inverter and smoke rolled out of it, it would be out of service until I found out the part that caused the smoke. Inverters don't usually smoke unless something failed.

ummmm...

Problem solved or the beginning of a new one!
Started by checking all 110 volt breakers and even going as far as to test continuity of each breaker, I found none tripped. Although, I had checked the breakers on the inverter unit last night. I decided to revisit them. After disconnecting shore power and reconnecting several times in my quest, I found one of the breakers tripped. Pushed it in and the smoke rolled out of the inverter. After the smoke cleared, everything works as it should. For now.

Welcome to RV.net!
Some inverters do not have a pass through function. Check manual for your inverter. Post make and model of inverter for better responses.
You may need to plug TV into another outlet.

Does anything else work on shore?
