Operation CHARM: Car repair manuals for everyone.

General Description

In addition to the features of a conventional (non-pulse) wiper system (low and high speed), the pulse-type Windshield Wiper/Washer System includes an operating mode in which the Wipers make single strokes with an adjustable time interval between strokes. The time interval is controlled by a Solid State Timer in the Windshield Wiper Motor. The duration of the delay interval is determined by the delay rheostat in the Wiper Switch.

The Windshield Wiper Motor is protected by a Circuit Breaker. If the Wipers are blocked (by snow or ice for example) the Circuit Breaker will open the circuit. The Circuit Breaker resets automatically when it cools.
