    Trailer lights

    I'm guessing and hoping it's a ground
    When I hook my camper to one of my trucks, the left brake and turn signal work along with running lights. This is with a 7 to 4 adapter. The camper doesn't have brakes so don't freak out. It's a 7 pin for charging the battery.
    When I hook it to the other truck that has a 7 pin, the right side works but no running lights. The one light that works is very bright compared to with the adapter on the first truck. Is this a ground issue?

    Are you using the same 7pin - 4pin adapter on the second vehicle?

    tested the 7pin's on the truck to make sure they're wired correctly?

    Are you hitching up the trailer or just connecting the plug?

    Just want to know how many variables changed when you changed trucks.

    The second truck has a 7 pin.

    You're first post seems to indicate you used a 7pin to 4pin for the first truck, thus it must have a 7pin also?

    The first truck I hooked it to has 4 pin so hence the adapter. The second truck has a 7 pin so no adapter.

    So you have a trailer with a 7pin. Two trucks, one with 4pin and one with 7pin. And an adapter to connect your 7pin trailer to the 4pin truck.. is this adapter something you made? Checked the wiring to make sure it's correct? Easy to get backwards if you're looking at a diagram of the truck side when wiring up the adapter..

    I'd start with checking the connections at the vehicle with the 7pin, make sure that socket is 100% correct..

    It all worked last year with no issues. That's why I'm guessing/hoping it's a ground. Thanks for the help.

    Could be truck, could be trailer.. vibration and weather can play havoc on wiring that's a bit sketchy.. The working lights switch left/right (ignoring the running lights for a moment) seems likely that the wiring is wrong.. in some way.. Could be a bad ground I suppose, but either way it would have to be tracked down in order to fix. Good luck.

    Definitely sounds like you could have some grounding issues. I've seen lights ground out backwards to through turn signal/brake circuits when the grounds were bad
