Trailer battery charge
Have a '99 F250Super Duty. Battery wire to trailer is not charging. Fuses are all good. Does tapping the traier break activate this or is there something else I need to look at?

There is a relay for that, it's also key on power.
it's in one of the small relay boxes near the big fuse box under the hood.
