Electrical Issue

I have a 2008 32QBBS Wildcat. It has sat for 1.5 years covered. I uncovered the RV and plugged in the power. Everything ran fine, but the air unit had a droning sound while it ran. When I went back to check on it, I heard a squeaking sound coming from the power control box. Upon inspection, it seemed to be coming from the inverter. If you shut off the th ac breaker the sound would go away. After inspecting further, the two white rectangular boxes by the black and white power wire are extremely hot. A spark occured while sliding out inverter. Since that happened the air, water heater, fan, and stereo will not work. Also, last year the battery cooked. I was getting 19 volts plugged in. I have a 12v constant power supply to run the jacks and slides. With that plugged in, no power is coming to the fuse board. Is there a breaker somewhere other than the ones in the power control box?

Sounds like the power center fried. I would shop for a replacement.

There is usually a auto-reset breaker near the battery. They routinely go bad and won't reset.

I also agree with Lou, that converter is suspect. You need to check it out before using it again.

Thanks to both of you. I will look for that breaker. The odd thing is that all the breakers shut power on and off at the breaker, but no power at accessories. The GFI and all sockets work though.
