Tail Cancellation Check

NOTE: Tail cancellation refers to turning light control rheostat clockwise beyond moderate position, causing lights to illuminate fully and system to ignore automatic light control sensor.

Disconnect light rheostat control 8-pin connector. With knob turned fully clockwise, no continuity should be present. Turn Connect ohmmeter between rheostat control terminals No. 3 and 4.
