Wiper Motor Harness Connector:

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 assembly. The duration of the delay interval is determined by the delay resistor in the wiper/washer switch assembly.

When the wiper switch is turned off, the wiper motor returns the wipers to the end of sweep (inner wipe position and then reverses, activating its external depressed-park mechanism to lower the wipers to park position.

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 through CKT 113 and terminal "F" through CKT 112.

The length of delay tine between sweeps is controlled by the variable-pulse delay resistor. The delay is adjustable from 1 to 32 seconds.
