[Hondaking1976]

I just recently bought a used camper that we had hooked to shore power for 3 weeks or better and the slide was working perfectly took the camper camping hook to back in the shore power and I had the battery cables touching the lights eventually went out in the camper it trip the GFI in the bathroom we reset it and all the lights now work but the slide only works on battery power and not Shore power does anybody know what's going on

Welcome to RVF, @Hondaking1976; glad to have you join us.

Without some specifics on the type/make/model/year of the "camper," it is nearly impossible to diagnose a possible cause of your electrical problem. A wild guess would be that you have a problem with the inverter (tripped breaker/blown fuse, failed unit. etc.) that provides 12V power when plugged into shore power.
