Pulse Operation

With the wiper switch in DELAY (pulse), battery voltage is applied to the wiper motor cover through the accessory voltage circuit. Controlled voltage is applied to the wiper motor cover through the windshield wiper switch signal 1 circuit and the windshield wiper switch signal 2 circuit.

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