I have a 76 chevy caprice, I cannot get my brake lights to come on when I step on the brake, my yellow wire isn’t reading any volts or my dark green wire either, but my brown wire has voltage, is anyone familiar with this problem
Test your pedal switch under the dash . Follow the brake pedal till you see the switch that activates the brake light and using a multi meter see if you have power coming in and going out
