Trailor light problem need help

[screwdriver]

With your test light first check at your four plug adapter.. Hook the ground part of the test light to the white wire and probe your brown or black wire to see if you have current. Make sure that the ground is good, this is the problem most of the time. Just because the turn signal blink don't think the ground is good because can get some ground from each other. Usually if the ground is bad the lights flash alternatly. -----Don't go thru a lot of trouble without checking the bulbs first.

I had a bad ground. From the truck. If the ball rubbed enough the lights would work. Making the ground.

I sure do thank all of you for the insight.I tell you this board is about the best thing in the world to get answers to problems that occur to many of us. I have learned a great deal from you folks and I do appreciate it. I guess I am going to get on this problem first thing in the morning and get it solved. Maybe if I get the lights working I can still go fish in the evening as I won't have to be home before dark. Wish me luck, and thanks again guys.Hope I can return the favor sometime.

Check under the hood , I had the same trouble last year...turned out to be a blown fuse..look for a fuse labeled as "towing"

Alright I just looked at the link that Wiskers provided and it made me think of something. This truck was set up with trailer brakes when I bought it. Could this have anything to do with my problem?

[Crappie Chaser]

No, the brakes should not be the cause...My problem was the fuse, and more likely thats your problem also. There is a separate fuse for each the trailer lights and the brake/turn signals. When a fuse blow, that means there can be a short or a wire touching the trailer frame. The most likely spot where the wires may rub to the frame is where the wires feed through the holes behind your rear or side lights.
If that is not the cause, check the ground. Try hooking your trailer to another vehicle, and if it lights up, then its the ground connection, wiring, or blown fuse on your vehicle. If it don't, then its definitely the wiring on the trailer. Hope this helps.

I had the same problem with mine. Make sure the ground wire on the trailer is making connection. Should be near the hitch, screwed to the trailer. My truck is a 2005 chevy and the running lights on the trailer wont work until the truck is running. Crank it and see what happens.It took me hours to find this out. BILLY

3GIRLSDAD, welcome to the not so exclusive world of trailer light problems. I've been pulling trailers since 1960 and had plenty of problems. Usually had to do with bad ground or shorted wires. Make sure that you are grounded to the trailer and not through the ball, that's been a problem for me in the past. Go to wallyworld and buy a tester that plugs into your truck plug and make sure that you are getting juice to the trailer. Good luck, keep plugging and you'll solve the problem. One other thing, I suggest that you solder all connections, wire nuts will eventually give problems.

Okay, 3girlsdad. The suspence is killing me, WHAT was the problem with your trailer lights? That is assuming you got it figured out. Curious???? Ferdi
