The left and right brake lights are not working, but the center brake light does work. The bulbs have been replaced and tested and both filaments in each bulb work. My meter reads a constant 8.6vdc across the terminals on the sockets whether the brake pedal is pressed or not. The center brake light reads 12.4vdc only when the pedal is pressed. I pulled and tested the 3 fuses (13, 14 and 15) related to stop lights. They all checked out and I am reading 12,4vdc at the fuse box. A wiring diagram would be greatly appreciated. Is it a single feed to the brake controlller from the switch which then energizes the 3 circuits for the brake lights? Any way to test/repair the brake controller or is something you just replace?
