Good morning I'm having trouble with my lighting on my trailer every time I roll the Single loghts four-way lights and brakes lights don't function correctly and my abs trailer goes on in my cab and my relay it's getting hot and everyte I hit a bump the lights come back on or if sweave to the right and left when I which lanes but not all the time already took the trailer to get a check and nobody is to find the problem and they told the trailer is OK
More than likely a ground problem. Don't know what advise to give other than check your grounds. Ground problems can make you pull your hair out.
So they come on when you hit a bump. Is the pigtail connector loose where it plugs in to either the trailer or the cab? If you move the connector and the lights come on there's your problem. If not then it's probably a broken wire in one of the connectors, most likely the end that plugs into the trailer as that's the one that gets moved a lot. Lots of guys pulls on the wire when disconnecting from a trailer instead of grabbing the actual plug which will cause breaks.
I tried a new pigtail and he kept doing the same thing took the trailer twice already to get it checked but still nothing
split the connectors....look at the picture above.....see how the pins have a little split in them? Take a pocket knife and stick it in that split and make them a bit wider....all of them
indeed.....they're brass and will break easily......just wedge them enough to split them and make better contact,,,,,mebee half way down the connector
I'm not trucker yet but i am an electrician. Sometimes relays build up crap on the contacts from the constant arcs overtime and also sometimes a reason of them getting hot. Hitting a bump can cause contacts not to stay open or closed. There are other relays in the fuse block that are the same most likely the AC relay you can switch it with. Obviously make sure the pins and numbers all match up before you switch them.
