Headlight Doors - Automatic: Testing: Motor

Using jumper wires and car battery as source of power, apply current to motor terminals after limit switch and check motor operation in both directions.
CAUTION: This test bypasses limit switches and power should be applied only momentarily to avoid system damage. If motor draws current but does not operate in either direction, motor has an internal short or a locked armature and must be replaced. If motor draws no current, an open circuit exists and motor must be replaced. If motor operates, apply power to terminals before limit switch. If motor now operates in both directions, limit switches are good. If motor fails to operate, check limit switches.
Use jumper wires at bulkhead-disconnect to check for voltage at terminal for both lights on and off. If no voltage present for either position, test for loose wire at "H" terminal of headlamp switch, loose wires on headlamp motor relay or faulty circuit breaker.
