With Pulse

With the Windshield Wiper/Washer Switch in "DELAY," battery voltage is applied to the Windshield Wiper Motor CKT 113. Voltage is also applied to CKT 94, and the pulse delay resistor in the Windshield Wiper/Washer Switch. The battery voltage at CKT 113 energizes the Windshield Wiper Motor Park Switch Coil, which closes its contacts. In response to the voltage at CKT 94, the Solid State Timer momentarily closes contact "A" on the WINDSHIELD Wiper Motor Cover which applies battery voltage at CKT 113 to the contacts of the Windshield Wiper Motor Park Switch, staring the Wiper Motor.

A mechanical arm (end of sweep input) operates contacts on the Windshield Wiper Motor Cover, which causes contact A to open when the Wipers have completed their sweep. Since the Windshield Wiper Motor Park Switch Coil remains energized, the Wipers do not park but remain just above the "PARK" position until the Windshield Wiper Motor Cover closes contact "A" again to start another sweep.

The length of delay time between sweeps is controlled by the variable Pulse Delay resistor. The delay is adjustable from 0 to 25 seconds.
