No brake or turn signal lights
I have a 2005 Excursion, 6.0L. Used it to pull a small trailer this past weekend. All lights, turning signals, brake lights worked fine upon hookup and at least the first 2 hours of the trip. (checked again at a break) Went to start the truck after sitting for 3 days hooked to the trailer, and the batteries were nearly dead. Found no interior lights left on after getting it jumped and running, so I assumed that I had a problem with my trailer wiring. After arriving home, I realized my hazard lights were not working, then realized that my turning signal or brake lights were not working either. I checked fuses that relate to brake / turn signal lights and towing. All fuses I checked had continuity. Running lights work fine. My tripometer was also reset, but I attributed that to the batteries being dead. Any ideas?
