Any body know how to fix it?

[theyyounggun]

These are normal bulbs. The lights are brand new but the harness is...........well new. It is 30 years old but I never used it and took it out of the package this weekend. I have been thinking to just go ahead and buy another one and re pull it. The lights ground the mounting bolts on the lights.

I just thought about this..... on my guide ons are where they are mounted to and they are painted. I bet that is were they are not getting a good ground. I will try that tommorow.

BINGO! That would do it. =D>

This is why I have a separate ground wire from the trailer frame, up to the mounting bracket on each of my guides, on both my boat trailers. That way, it ensures a solid connection, no matter what.

If you want to know for sure, just take a test lead with alligator clips, and clip one end to the trailer frame, and the other end to one of the mounting studs of your light. If it works, then you know for sure.

That didnt work either! #-o Im going to go try the alligator clip method. But I polished up the contacts on the trailer to bare metal and it didnt fix a think...

Is this a tilt trailer or is the tounge bolted on to the frame? If you have either of these and you don't have a ground wire run all the way to the back turn the bolts holding the tounge to the frame. Father in law had the same thing and the marina turned those a couple of turns and everything fine. Hope this will help. You could also run a temp ground wire to the back and see if it works

It was a tilt trailer but now it's welded together. I took a oeice of wire and connected it to the two bolts on the light. And ran it up to the front of the trailer. Did the same fr the other side. Connected them up front and put them on the trailer and put the ground from the extension on them. Nothing. Then I just put them on the trailer without the extension ground. Nothing. When I say nothing that means that both blinkers flash. And when I press the brake the taillight goes out.

I guessing that you have an electric tester. Take the bulb out of the lights and ground the tester to the frame and touch the hot post in the center of the lights socket and then try the lights and see if you get a reading. If you do the ground is good. Try brake lights headlights and turn signal on each light. If you don't get a reading thru the light socket check for a reading thru each wire at the lights before it goes into the light itself. This will tell you if the light is bad. I have had some of the newer lights that you push the wire in and it locks no make contact at the lights. I have also found broken wire at this area of the light fixture also.

If you can turn on the left or right blinker of the tow vehicle and both lights of the boat trailer blink, they you've got one of two things wrong. Either you have the vehicle pigtail/trailer wired wrong or you have a short in your wiring. With proper wiring and no shorts, the 12v blinker voltage runs down one wire on one side of the boat and there would be no way to get 12v going to both sides at the same time.

Havent been on in a couple days but...I fixed it!!! I tried a different type of wire for the light and it worked.

 

[zseverns]

I am having the same problem could you tell me exactly what you did to fix it.

Find one of your buddies trailers and book to it . It may be your truck

 

[theyyounggun]

After connecting the wires several times I had run out of wire. (Tinned strand) and it would work. But I needed more wire so I just simply cut a piece of stranded. That's when it quit working and I didn't think anything about it. But I needed more wire once again so input another peice of tinned in and it worked!

 

[Miller13]

That's good you found it , those old trailer kits that you could buy at a parts store gave one my friends a rough time once , It was the kind to go in the taillight harness since that episode I check the tow unit first anytime something was working good then starts acting stupid

I'm glad you got it fixed but you'll never convince me that installing a different type of wire was the solution. I understand that the problem is fixed, and all you did was replace a wire, but that says to me that you corrected a bad connection or a short or some other issue when you replaced that wire. LoL

That's what I thought, because the wires were the same size and everything. It looked like it had a good connection but i think the strands were not getting a good connection because they were the lights where you push the wire into the lights.

Yea, I hate to use that type of light with the push through wires but it seems like most companies are going to that design.
