Bigfoot tripping house GFI
2008 Bigfoot 9.4. Replaced the converter early this spring only because it was boiling my batteries. Got a Progressive from Best Converters. Son and I replaced it. He works with DC a lot on the job. I haven't actually used the camper since, for a variety of reasons. I usually plug the camper into a house 110volt outlet every 4-6 weeks to keep the batteries up. The exterior outlet I use is a GFI. Several weeks ago, after it was plugged in, I noticed the LED lite on the extension cord wasn't on. The outlet had tripped its GFI. I reset the GFI and same thing again. Went to another GFI outlet and it did the same. This hasn't happened before. Then used a non GFI outlet in my garage and all seemed well. Charged the camper for several days.
Only thing I can think of besides a loose connection on the converter is the ground wires that are bolted to one of the Bigfoot tiedowns. I had to re-arrange them a bit when I installed a Torklift tiedown "stiffener".
I haven't done anything yet. It's only 95F and 90% humidity. I'm thinking the first somewhat cool morning I'll dive into it. Guessing I'll clean the eye connectors on those ground wires and be sure they have clean metal to metal contact on the tiedown. Oh, I did replace the30amp plug on the camper cord.
I'm not sure how to check ground continuity. Maybe ohm from the plug ground to any ground I find in the camper?
Or, since it takes only milliamps to throw a GFI, just ignore it??
My house outlets don't throw GFI on anything else.
edit add: Eh, wait a minute...I had a brain flash. I was using a $4 30amp to 110volt adapter. Little hockey puck thing. Tomorrow I'll try a dogbone. But y'all keep thinking how to diagnose this, or ignore it.
Thanks in advance.
