    Default 93 1500w/t brake light switch prob.

    Anybody know how many volts I should be getting to the brake light switch. I keep burning the points up inside the switch. When truck is off I have close to 12 volts however when its running its getting the full power of the alterator at 13.8 volts. Is there a diode somewhere between the alt. and the switch??? Anyone have a wiring diagram for that year. thanx cw

    Sounds like you have a short in the brake light circuit. 13.8vdc is ok. Are the turn signals ok? The stoplight circuit is wired through the turn signal switch. You could have a problem with the wiring in the steering column.

    Goto Enter your vehicle info and under the "repair info" tab then "Vehicle Repair Guides" and drill down to the wiring diagram.
