Question about 2003 Chevrolet Silverado 2500HD
I have an 03 Chevy 2500HD that I installed a brake controller on. After installing the controller, I hooked it up the camper to see if the camper brakes worked. The controller readout display began flashing random numbers followed by a short circuit error. I hooked the camper up to another truck and it worked fine. I've taken voltage readings off of the 7 pin connector but I'm not sure what I should be seeing. Any thoughts?
What type controller did you install? Is this a camper or trailer? Is the controller hydraulic plumbed into master cylyder? Important to know how to adjust rheostat for sensitivity. If set at minimum the system is basically on the edge of not sending any signal to towed unit. The intructions should explain how to make this adjustment. If set too sensitive trailer brakes will lock up before the tow vehcle starts to brake. Controller should be set so trailer starts braking just befor the tow vehcle. If not the trailer will tax the tow vehicle brakes by pushing. Its set right when you feel the combination stretching out. trailer first then tow vehcle. Good luck and remember, if truck brakes first and too hard you risk a jacknife. All light voltages should be system voltage. Brake voltage is variable depending on setting on controller. Understand your breakaway brakes and how they work. breakaway breaks require an auxillary battery. Again, good luck and you know where to find me if I can be of anymore help.
