Has anyone had their running lights stop working? Brake lights still work but cant get the running lights to cooperate.

Are you sure you have a good ground from the vehicle?

Yes I have checked vehicle to trailer and the ohm meter shows they are connected.I have found a connection at the front fender light and one mixed in with the tail light when following the brown wire so I am going to go redo those. Yellow looks to be the turn signal so it may be just total different line. So it may not be the ground but the actual power line to the lights.Fixing trailer lights in the rain, while in a rush is quite fun………

I redid the connections at the tail light and the side light, no luck…I am going to see how the line is split between the left and right for running lights..Does the tail light use the same ground for turn signal and running lights?

The trailer frame is or should be the ground for all lights & brake solenoid..The lights just have short wires bolting to the trailer frame. I have found sometimes you need to go around and loosen all the bolts that have the ground wires attached and rotate them a few times then retighten to regain the ground circuit.

You may have already checked this, but trace your wiring all the way from the front of the trailer to the back. I had a similar issue with the trailer on my Baycat, except it was the brake light didnt work. There was a splice about a 1/3 of the way back from the front of the trailer on the brake wire. It looked good, but when I touched it, the wire just fell out of the sleeve that was placed over the splice. I had been doing everything you did, spent several hours trying to figure out what was wrong, then found this. I redid the splice (not sure why there was a splice there) and everything worked fine.Last edited by billius on April 29th, 2011, 12:30 pm, edited 1 time in total.

Is the ground wire in the vehicle connected to the wiring harness so that you are not using the ball as a ground. That doesnt work very well.

I have redone any connections on the side that wasnt working but it doesnt look to have worked. I think the problem is where the wire (looks black or brown) splits into two and one runs down the left, and the other runs down the right side. It is working down the right but tracing it down the left it doesnt get to about where the spare tire is. I think I can fix it by splicing the right side with the left, but I think it would be better to find the split and fix it there.

I am currently experiencing the exact same issue with the left side tail and side marker light on my 2008 Puma trailer! Some times they wold work, some times they would not. Friday, I traced all of the connections for the left side tail and marker light starting at the rear of the trailer and worked my way to the plug in connection at the tounge and the plug on my truck. Everything on the trailer seemes to be OK. On my setup, I have an adapter from the flat 5 wire plug on the trailer to the round 5 pin plug on the truck. It appears that the problem may be in these connections. I cleaned the pins and recpticles with emory paper and then sprayed them with electrical contact cleaner. The lights worked fine Saturday. Time will tell if this solved the problem.

I had this happen a few times in the past but not on a cat. Each time it ended up being a lose or broken connector inside either the male or female plug. Since the brake lights and I assume the turn signals and flashers work also, it probably is not a ground issue. You can test the truck connection with a volt meter. Test each connection with break lights and flashers, then you should be able to figure out which pin is your running lights unless BCB knows already. Check that pin on the truck connection and if you have power there with the running lights on, then it is probably the connector on the boat. Hope that helps some but someone might have an easier way to test it.

I had to replace most if not all of the 4 running lights ( 2 red and 2 amber) with the new LED ones from the web site. One of those had to be replaced in less than a year. Package says water resistant so I sealed the back of each with silicone at BassCats recomendation. You can test each light to see if it is bad or still good.John

Running lights are all running lights, not just market light. Those are run from a brown wire source and you can check output by cross plugging that trailer harness into another lead for green or yellow on the trailer, which are the brake ligths, green for right, yellow for left. You really cant mess up cross plugging as the pins reference positive and the receptacle is the ground reference.

Check truck fuse first. Try a plug/cord from trailer to truck also. Those two have happened in my experience.
