Tripping GFCi over and over
Looking to take my parents’ trailer out this weekend after 2 years of sitting. Each time I plug it in to a GFCi outlet (240 with 120v adapter and 120) it’s tripping the breaker. I’ve read the other posts on this subject and turned off each circuit one at a time, trips. I’ve switched to other outlets and they trip. I’ve turned off every breaker in the trailer and it still trips. I’ve swapped extension cords and plugged in the main shoreline and it trips. I plug it in to a non GFCI circuit and it’s fine. Anyone have a starting point to troubleshoot this? Thank you in advance.
