Earth

The gauge is earthed (grounded) by the large tab at the bottom. This means the gauges won't work properly until bolted in place. For testing, an earth wire can be attached.

BRAKE SYSTEM WARNING LAMP

If either half of the dual brake system fails, the brake warning light (BRAKE) glows when brakes are applied. You must stop the car immediately and if you can safely operate with two-wheel brakes, move your car at reduced speed to the nearest service station.

This warning light is also used as the parking brake warning light.

Before starting, if the warning light does not glow when the parking brake and ignition switch are on, have the electrical system checked.

* Brake pressure warning switch
* "Hand Brake is on" reminder
