I have an old horse trailer that doesn't seem to get power to the brake lights. Is there a way to check that the connnector on my truck is actually putting out power?
I realize that the likely culprit is the plug on the trailer(it is somewhat corroded) but I would also like to eliminate the possibility that the problem may be with my truck.
