Brake Stop Light Switch & Circuit Test
NOTE:
This test should be performed whenever brake application will not disengage speed control. If both stop lights are not working it will cause speed control malfunctions.
- Check for stop light operation with a maximum brake pedal effort of 6 lbs. (2.7 kg). Check brake pedal actuation and stop light switch if pedal effort required is excessive. If stop lights operate correctly, check battery voltage at Black/Green stripe wire at 6-way connector.
- Depress pedal until stop lights are on. Check voltage at Red/Black stripe wire at 6-way connector. If voltage readings differ by more than 1.5 volts, high resistance exists in stop light circuit and must be corrected. If stop lights do not work, the stop light switch, supply circuit and bulbs must be checked for correct operation.
