Converter issues

Anyone ever seen a converter cause an AC issue like shorting out the GFCI?

My 30 amp converter has no output between the positive & neutral & 20 volts between positive & ground. Thing my converter is fried.
I was running my TT off a generator and only running the heater (12v & propane). Then the refrigerator started to turn itself on. I would turn the frig off & it would turn itself back on. Then we noticed a burning smell & poor the GFCI outlet in the bathroom fried. Pulled it out and removed it after killing the power. Applied power again with nothing running & everything was fine. Turned on only the heater again and the GFCI outlet in the kitchen started to fry. That is when I removed the converter and started measuring.

Very confusing.

You seem to be describing a "three pronged" 120v receptacle where HN voltage is zero and HG is 20v AC? Where are you measuring these exactly and what units is the meter switched to?

Or are you getting 20v DC on the 12v system?

A converter is plugged into 120v AC and makes 13.x volts DC. It is part of the Power Centre that is 30a AC capacity with some circuit breakers in its AC panel. It could be the cause or it could be a victim or it might be fine once the language/definitions are clarified here.

More likely your shore power cord plug or its adapter is faulty where plugged into the generator. The generator may have one of those "bonding" things going on that gets confusing :(

By "heater" do you mean "furnace"? The fridge coming on by itself--is it in "auto" or gas or just AC? Did it come on under 12v or 120v?
