7pin trailer light question??? need help
Also posted in excursion thread...
2000 x the only trailer light(s) working are the running lights. Brake lights and turn signals/hazzards won't work. It's not the trailer, it works on another truck. No voltage reading at my connector on those pins (left or right stop/turn). Voltage on running light pin only.
Is there a relay or a fuse that could be faulty??? I don't have the owners manual, so I don't know what relay is for what function??? I checked every fuse with a test light all seemed ok. This is driving me nuts...any help would be much appreciated.

Thanks, both were blown...Don't know what caused it??? Looks like the previous owner tapped wire for a reciever brake light, maybe during the course of probing wires he grounded out somehow???? Havent replaced the fuses yet. Thanks for your help.....

Check the trailer plug on the truck it self it is probley where the corrtion is that is the first place to go . I have found out with all of the road salt during the winter takes a toll on them. every other year I have to rewire that set up. Good luck.
