Delay (Pulse) Operation

With the Wiper/Washer Switch in "PULSE," battery voltage is applied to the Wiper Motor Assembly at terminal "B" of connector C1 through CKT 91. Voltage is also applied to terminal "F" through CKT 94, and the pulse delay resistors in the Wiper Switch Assembly. The battery voltage at terminal "B" energizes the Park Switch Coil, which closes its contacts. In response to the voltage at terminal "F," the Solid State Timer momentarily closes contact A on the Cover Assembly which applies battery voltage at terminal "B" to the contacts of the Park Switch, starting the Wiper Motor.

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

The length of delay time between sweeps is controlled by the delay resistors. The delay is adjustable from 0 to 25 seconds.
