Anti-Theft Controller Circuit

NOTE: With anti-theft controller disconnected, starter is inoperative.

Using an ohmmeter or voltmeter, check for continuity or voltage between ground and anti-theft controller connector terminal specified in appropriate ANTI-THEFT CONTROLLER CIRCUIT TEST . SeeFig 1 . If all circuits test as specified, replace anti-theft controller.
