Trailer light connections
I have had many people ask about trailer light connection problem and the biggest one I have had to answer is.( When connected and the lights turned on than with the brake is depressed the trailer lights shut off. What causes this?)
The answer to this is simple. You have a bad ground problem between your vehicle and the trailer. This can be solved by looking at your trailer wire connection plug. Fray a little bit of the white wire on the plug. some place easy where you can wrap it with electrical tape when you get done. Take another wire and connect it to the frayed part of the wire. once this is done take the wire and connect it to a part of the trailer that is free of debree,rust,corrosion and some place that will not be subject to coming off or broken. Once this is done turn your lights on and depress the brake. If your lights do not go off than permamantly attach the wire to that location and wrap the wire at were you have frayed it.
If this does not fix the problem than look at the connection on the vehicle. Once again take another wire and connect it to a frayed point on the white wire of the vehicle. find a spot on the vehicle to connect the wire to. than try your lights again. This should work in all the cases i have had to deal with. if it does not feel free to contact me and i would be glad to help you at any time.
