Hi all. Thanks in advance for your help. I know very little about electronics, so feel free to dumb down your responses. Here's the issue:
I have a 2005 Nissan Fronitier Crew Cab with an aftermarket (U-Haul) hitch. U-Haul also installed the wiring harness. There is nothing wrong with my trailer wiring harness or lights, as they were tested by my local boat mechanic twice. Both are 4 pin. When I connect the two, and turn my truck ignition to accessories (without starting the truck) the turn signals and lights work fine on both the truck and trailer. However, when I start the truck, I get one blink on a turn signal and then nothing more happens on either truck or trailer. No brake lights either. Sometimes, a 10 amp fuse will blow on my truck, but not always. The mechanic is baffled, but he thinks it has something to do with the anti-lock brake system on my truck that disables something when the ignition is on. Anyone encounter this or have any thoughts? Thanks!
