why wont my lights work

[ranger69dv]

I have a 1999 ford ranger, and it came equipped with a flat for prong light plug. I just bought a boat, and the trailer has a round seven prong plug on it. So i went to the store and bought an adapter and hooked it up but when i plug it in i get nothing. Why

The ez reason is the trailer hitch isn't grounded well on the truck ball. Use a test light to be sure you have power to truck plug. Good luck.

Agree, probably a ground issue. Friend of mine had same situation with a new pop-up camper. The round 7 adapter had a ground wire that he had to ground to his truck chassis.

I have one of them adapters and mine is straight thru with no wires exposed at all.<br />Your trailer plug just plugs into it and then you plug the adapter into your truck.<br /><br />But check to make sure you are getting juice at the back of your truck first and then plug the adapter into the truck and check it.<br />Nothing says you could not have got a bad one.
