With Pulse

In addition to the features of a conventional (non-pulse) wiper system (mist, low and high speeds). the pulse type windshield wiper/washer system includes an operating mode in which the wipers make single sweeps with an adjustable time interval between sweeps. The time interval is controlled by a solid state timer in the wiper motor cover. The duration of the delay interval is determined by the delay resistor in the wiper/washer switch.

When the wiper switch is turned "OFF," the wiper motor returns the wipers to the inner wipe position. and the wiper motor reverses activating its external depressed park mechanism to lower the wipers to the park position.


Pulse Operation
With the wiper switch in DELAY (pulse), battery voltage is applied to the wiper motor connector at terminal "B" through CKT 243 Voltage also is applied to terminal "G" through CKT 478 and terminal "H" through CKT 477.

The length of delay time between sweeps is controlled by the variable pulse delay resistor to the wiper/washer switch. The delay is adjustable from 1 to 22 seconds, nominally.
