Brake Warning Light Circuit Operation
The brake warning light receives battery voltage with the Ignition Switch (X134) in position II. It is grounded by the Brake Fluid Level Switch (X111) when the brake fluid level is low. It may also be grounded when the Handbrake Switch (X191) is closed. The brake warning light is also grounded by a 3 second timer as a bulb check.
