Warning Light, Brake Fluid Level

Symptom
Brake fluid level warning light inoperative.

NOTE: If the brake fluid level warning light (or other lights in the circuit) come on when the car is started, there is probably no fault in grounding via the ignition switch. The power supply to pin 5 is probably OK

Light Comes On When The Car Is Started:
With the ignition on, check for 12 Volts at pin 2 on the brake fluid reservoir.

If no voltage is discovered on pin 2, check pin 5 on the combined instrument.
- If 12 V is present, there is no fault in the power supply.

Check the light.
- If the light is intact, fit a new circuit.
- Also check that pin 1 is grounded.
- If no grounding is found, check the ground supply.
- If grounding is found, fit a new float.

If there is no voltage present at pin 5 on the combined instrument, there is a fault in the power supply-

Light Does Not Come On When The Car Is Started:
Check that the lamp comes on when the float is pressed down in the reservoir.
Check pin 1 of the main instrument display panel.
- Test position of ignition switch = 0 V.
- If 0 V: replace the circuit board
- If voltage is present, check ground C on the ignition switch.
- If grounded, install a new ignition switch.
- If not grounded, check the grounding.
