I had a Collins. I recall that when the GFI cut out, I had to go behind the wall in the front storage to reset it. I also looked everywhere and finally called Collins (still in business then) and they told me about the GFI reset behind that wall.
I can't remember where the inverter was located, Could be behind there also, since the 120 fuse box was in the bedroom.
Hope this helps a little.
