We're getting closer! Put a new ball and hitch on the truck, and actually hooked it up to the trailer, not just plugged in the trailer lights
, and all clearance lights
work. And the running/brake lights
work if we hold a wire to something else other than where it is wired in currently.Right now, the brake light
is grounded with the black wire from the brake light
screwed into the backing circle of the light
area, which is painted and not much thicker than a pie plate! So, are you saying that this black wire coming out of the brake light should be connected to the white wire system inside the trailer, and on to the white wire that is then screwed onto the tongue.
Also, when checking all the wiring, I see another potential problem. Behind the outlet on the front of the cupbard, there is a white wire and the black wire hanging free in space. But the outlet still works. Was there something else there in the past likely!
Thanks for all the help. Soon we'll have running lights, and be able to leave the driveway!
