wetwilly 03-13-2009, 10:40 AM Hi there. I have what I hope is a simple ploblem with a simple answer. I have a Prodigy brake controller semi-permanently wired into my truck (07 classic duramax crew cab). Just noticed the light that is usually on on the controller is off. Is there a fuse somewhere that is dedicated to the brake controller circuit? Thanks in advance, Steve John R 03-13-2009, 09:28 PM Not sure if yours is the same as mine, I have an 03, There are fuses in the left dash that control all of your trailer functions, including the power for your controller. trailwhale 03-14-2009, 02:30 PM On the Prodigy only the little red lights will be on unless a trailer with brakes is connected... Some trailer related fuses are underhood and some in left BEC (fuse panel) in interior Diesel Dragon 03-14-2009, 08:42 PM And if the truck has been sitting for a while the little red light goes out, turns on again when you touch the brake pedal. woodchuck2 03-15-2009, 07:52 AM And if the truck has been sitting for a while the little red light goes out, turns on again when you touch the brake pedal. X2, shows 2 small led's with no trailer, shows NC when manually applied and C when trailer is connected. If you have nothing at all check your fuses, i would also recommend checking them with a test light too. | ||
