OP here,
I have rechecked all the fuses on the fuse panel located next to the converter. All are good. Found one more up by the water tank and sureflo pump. It's good and it is only for the water pump. Up on the A-frame where my batteries are kept I have a cut-off switch and just "downstream" from that switch are four 12volt circuit breakers (short stop). They are very corroded. The lugs are very rusty. I tried to scrape through the rust to get my test meter on them and see if 12volts was getting through them and I don't see voltage. I'll take Bobbo's advice and just replace those 4 corroded circuit breakers.
I don't believe the GFI is a factor because I am only dealing with 12 volts. I also tried to post pictures but have not been able to.
Thanks for everybody's input.
