Re: Trailer Lights driving me mad
OK, so firstly, THANK YOU ALL. Just got home from father in law's and everything is working.
So here goes. First we unplugged all the bulbs and put one tester end on the ground end of the plug and the other end on each of the three pins one at a time on each of the three pins. If there is a tone that means there is a short. There was no tone so no shorts.
Put the small bulbs back in but kept the 1157's out. Took some sand paper on a dowel and cleaned the inside of those sockets in the rear lights. Cleaned the point of contact from the ground to the rear light. Things looked ok. with all grounds cleaned.
Took a 12V output charging brick from something we found in the garage, plugged it into the wall and started using it to test. Everything worked except for the right rear light. The one that had the initial turning signal burnout. With the right turn signal pin getting the current both lights would blink on the right and the marker lights would be super faint. With the lights signal, the rear right was just dark.
Ended up pulling all the wiring to find the problem. It was the ground connection to the rear right light.
As you recall, the 4 pin connector broke up into 8 wires that went towards the lights.
2 wires went to the marker lights. This was a brown wire and a white wire, the headlight wire and the ground wire. There was a two pin adapter that attached to another unit that had 4 wires come out of it, each pair going to each marker light. That 2 pin plug had electrical tape wrapped around it to prevent it from coming apart due to road vibration and such.
3 wires went to the right rear light. This was a brown wire, a white wire, and the green wire, the headlight wire, the ground wire, and the right turn wire. There were two plugs at the end. One two pin plug for the headlight and right turn wire and another one pin plug for the ground wire. The rear right light had the same 2 pin and 1 pin plug on its wires. So this one pin plug for the ground wire was not connected. These two plugs did not have any electrical tape on them. I assume that is why it came loose. I made sure to secure them VERY VERY VERY well with electrical tape prior to putting it back in.
The last 3 wires were identical and went to the left signal light with one exception. The Green wire was a yellow wire, the left turn wire. The two pin plug on the left side was fine. But the 1 pin ground plug was very loose and was probably gonna drop out as well. I made sure to secure that one with electrical tape as well.
So basically i think the 1 pin ground plug in the rear right side was super loose and i pulled it free when i removed the light when changing the bulb.
I think Karavan needs to use electrical table to fasten the plugs in the rear just as they do for the marker lights.
I rolled it out of the garage and plugged it into my car and all is good.
If you guys got this far down, let me say thanks for all the help once again. Sorry for the long winded response but I feel you guys deserved the full story.
