Resolved Magnum inverter main fuse

Sounds like you blew the GFI breaker and it needs to be reset on the outlet with the reset button.

Out of the 5 that I've found, two will not reset. I'll dig into it more tomorrow. Maybe missing a neutral somewhere. It sure does sound like a GFI somewhere though. Maybe one is bad.

I had a similar issue at my house. GFI tripped and would not reset. Turns out there was an electrical spike from the power company. It didn't affect all GFI just the ones on the leg that spiked. There was internal damage to all of them. Several had items plugged into them which didn't sustain any damage. All the GFI's had to be replaced.

On my 17 I’ve had to replace 3 of the factory installed gfi’s that would not reset. They were simply faulty units for some reason. All three have been in place for several years now with no problems.

I had to do the same on my 2019. I went with traditional house installs instead of the RVIA crimp style. When replacing one outlet, I saw where the wire was not pressed in firmly and could create a spark or loss of connection. My guess is this is your issue.

I read recently somewhere that Newmar acknowledged faulty GFCI outlets and they were replacing them under warranty. Probably recent years but we've heard plenty about GFCI outlet failures that I'd lean towards replacing them.

I'm going to replace the outside one with a standard outlet. At the eye Dr now getting dilated so I'm out of commission for a while. I'll report back when I find the problem

Something to consider though, when you're able to read again, is that they have worked this long and you can't discount there is a reason they are tripped.

Since everything was working fine till I decided to power down the coach, I don't think there's a major problem. Now, since I've replaced the main fuse to the inverter, everything is back up to normal except the slide power which I'm convinced is due to a GFI issue. I believe whatever I did in incorrect sequence blew the main fuse and took out the GFI's.

Half blindly poking around, I did find there was power coming to the GFI's, got both of them to reset and all is well once again. I plan on replacing both though before our next trip. Thanks for all the help and suggestions!
