I have an '02 K2500 Suburban and a problem anytime I hook a trailer to it. Last winter I was hauling my tractor home from my mom's place, where I just cleaned her driveway, and I started to slide. The trailer was borrowed and did have trailer brakes but I didn't have a controller to operate the brakes. Anyway, I was on the brakes the whole way down a long hill and I noticed all the dash lights, including the radio, dimming everytime I hit the brakes. I thought it was something messed up with the trailer wiring.
Fast forward to today. I recenlty picked up a nice little 4x6 utility trailer and was hauling some stuff to my MIL's place and I noticed the same thing happening again. This time though I was going through an adapter since my 'burban has a 7 pin connector and the trailer has a 4 pin connector.
I noticed when I put the brakes on the lights on the dash would dim the same as before but when I would turn my turn signal on the lights on the dash would blink in unison with the turn signals.
I just repainted the trailer last week and checked all the wiring. At first no lights worked so I started checking the ground when I remembered the fuses. 3 of the fuses for the trailer lights were blown. I replaced them. After that everything was good but I noticed the front passenger side marker/turn signal bulb was blown. I replaced it and all the lights worked. I used my 4-way flasher to test the lights and the turn signal lever to double check each side individually. Everything checked out okay. It was dark out when I tested so I pushed the brake pedal and checked for the brake lights to light up to be sure they working too. They were. I don't recall looking at the dash while I was doing this since I was focused on the lights on the trailer so the dash lights may have been dimming when I did this but I didn't see it.
So has anyone encountered anything like this before? I checked the fuses when I got home this afternoon and they are all good. Lights on the trailer are all working as far as I can tell. I'm seriously confused.
I'm leaving for PA Monday morning on a bussiness trip but I'm taking my Suburban and the little trailer to pick up some turf tires for my Kubota I won on Ebay. I'm a little nervous about it. I know PA troopers are pretty tough on trailers. I don't want to risk loosing lights and not knowing it then end up with a ticket while travelling with my boss.
Any help is appreciated.
