Converter and GFI issues...and how does a Converter work?

I have a 2015 Fuzion 345 and when I plug into a GFI outlet, it trips. Sometimes it trips the GFI right away, other times it might go a day before it trips. When I plug into a NON GFI outlet at home (when getting ready for a trip, it never trips the house breaker or anything on the camper...only when plugged into GFI).

I have researched it as best I can and from what I can tell, it isnt an Amp issue (only pulling like 5-8 amps max), but maybe more of a ground fault or something? I also thought it might be a bad power cord (which is possible as I accidentally got it pinched between the landing gear and the ground one time).

So today I shut off all the breakers at the control panel (where the converter is) and flipped them on one by one until it tripped the GFI...I was able to turn all of them on (and only drawing 3 amps) and as soon as I flipped the 20a Converter breaker, it tripped the GFI. So.....is this something like a bad ground on the converter or something wrong with the converter?

For the converter itself, it converts 120v ac to 12v dc, correct? It also charged and monitors the house battery I am guessing? If the above is correct, was I OK to leave the camper plugged in with all the breakers on, except the converter breaker which is off, and then I put a battery tender run from the other outlet on the house 12v battery. I am thinking this is ok????

Obviously I will have the converter short or whatever it is looked at, but for now am I ok having it as described above? Thanks for any advice and tips you can give.
  • The problem lies in your 120 V system and it may be that a wire is loose or shorted on the converter circuit. You can test the condition of your cord with a meter. I guess you already know it's not good.

    Nothing necessarily wrong with using a standalone charger rather than your converter but a battery tender won't keep up with average use and your battery will eventually die. In fact, if your battery is severely compromised, the draw from the converter may be affecting things.
  • Does the converter plug into a receptacle? Instead of turning off the breaker, unplug the converter and see if the GFCI still pops. Sometimes the converter is on with other receptacles such as the outside one that can get wet and then it is the culprit till it dries out.

    Yes you can float the batts with a different charger
