Brake Warning System

Circuit Description
The brake warning light goes on to alert the driver that the parking brake is applied, or that the brake fluid level is low.
It also lights as a bulb test when the engine is cranked.

Parking Brake
With the ignition switch in ON or START, battery voltage is applied from fuse 2 to the brake warning light. When the parking brake is applied, the switch closes and provides a ground for the light. The brake warning light goes on to remind the driver that the parking brake is applied.

Brake Fluid level
With the ignition switch in ON or START, battery voltage is applied from fuse 2 to the brake warning light.

If the brake fluid level is low, the brake fluid level switch closes and ground is provided to the circuit. The brake warning light illuminates to warn the driver of a low brake fluid level in the brake master cylinder. (NOTE: Check brake pad wear before adding fluid.)

Bulb Check
With the ignition switch in ON or START, battery voltage is applied to the brake warning light from fuse 2. The generator will provide ground to the circuit until the engine is running. The brake warning light is tested and then goes off,
