When brake pedal switch is pressed hatchback brake bulbs fail to light. Otherwise the position bulbs light when position light button is Turner on. I´ ve tested the brake wiring, and there's voltage on cold side of pedal brake and handbrake.
Ok, thanks Jim. When tested with screwdriver electrical tester, the pedal brake´s hot wire bright light, unlike the handbrake's white wire that fade light. The handbrake white wire's voltage could also be low from a poor ground?
The hand brake is not related to the foot brake electrically.
The hand brake has a single switch which completes a circuit for the dash light. Positive comes from the ignition switch, ground comes from the chassis. The switch on the handbrake completes the ground.
The foot brake switch completes a circuit for the rear lights. Positive comes from the battery, ground from the chassis. The switch on the pedal completes the positive.
