Pulse Operation

With the wiper switch in the DELAY (pulse) position, battery voltage is applied to the wiper motor connector at terminal B through CKT 143. Voltage is also applied to terminal D through CKT 113 and terminal E through CKT 112.

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