jasonnotperfect Posted October 14, 2015 Share Posted October 14, 2015 Working on a 2005 cv713 that came in the shop for no running lights. This is where the fun begins! After a couple of hours of the normal troubleshooting, I found that the 7-way for the trailer was interfering and causing a short. This truck is no longer required to pull a trailer, so I removed that 7-way wire all the way back. All running lights now work... Yay! Well, enter the demon. Now the trun signals don't work (they did before). The flasher is in good shape, but put a new one in just to be sure. No change. I inspected the turn signal switch and found melted wires in it. Those wires are for the clearance flash on the end of the stick. New switch and everything works untill I plug that switch in... then it blows the fuse for the running lights! I'm lost and my forehead hurts from trying to put a window in my shop wall!!Thanks in advance for any help.Jason Quote Link to comment https://www.bigmacktrucks.com/topic/42196-first-no-running-lights-now-turn-signal-switch-melted/ Share on other sites More sharing options...
hatcity Posted October 14, 2015 Share Posted October 14, 2015 when you cut the 7-way, did you separate all the wires?check the wires all the way back. Sounds like a short somewhere Quote Success is only a stones throw away.................................................................for a Palestinian Link to comment https://www.bigmacktrucks.com/topic/42196-first-no-running-lights-now-turn-signal-switch-melted/#findComment-307445 Share on other sites More sharing options...
jasonnotperfect Posted October 14, 2015 Author Share Posted October 14, 2015 i actually disconnected the wires from the buss bar before I cut it, but sillier things have happened. New problem thismorning though, when I turn on the head lights without the turn signal switch plugged in, all works well. Turn the key on, and the outside two cab clearance lights go out. Arrrgh!
