With Pulse

Whenever the ignition switch is in the "ON" or "START" position, battery voltage is applied through the WIP Fuse to the Front Wiper/Washer Switch and the FRONT WIPER MOTOR.

WASHER OPERATION

When the Front Wiper/Washer Lever is pulled, battery voltage is applied through the Front Wiper/Washer Switch to the FRONT WASHER PUMP. The FRONT WASHER PUMP is permanently grounded at G101 and will operate as long as the Front Wiper/Washer Switch is engaged. The windshield wipers operate in the "LO" position while the Front Wiper/Washer Switch is engaged.

INTERMITTENT OPERATION

With the Front Wiper/Washer Lever in the "INT" position, battery voltage is applied through the WIP Fuse to the coil of an electronic relay in the intermittent Controller and to a condenser also in the Intermittent Controller. The condenser charges to voltage and the relay is energized as soon as power is applied. When the switch in the energized relay closes, voltage is applied through the BLU wire to the FRONT WIPER MOTOR "LO" side. The wipers begin to operate at "LO" speed.

By the time the wiper motor makes one complete rotation (and the FRONT WIPER MOTOR Pawl and Switch has engaged), the condenser in the Intermittent Controller has discharged. This discharge in the condenser causes the Intermittent Controller Relay coil to de-energize, and the switch in the relay to open. Current flow to the wipers is then cut off until the condenser is recharged. In this manner, intermittent wiper operation is achieved through the charging and discharging of the Intermittent Controller condenser.


LOW OPERATION

With the Front Wiper/Washer Switch in the "LO" position, battery voltage is applied through the WIP Fuse and the "LO" contacts of the Front Wiper/Washer Switch to the "LO" side of the FRONT WIPER MOTOR is permanently grounded at G106, the motor operates at low speed as long as the switch remains in this position.

HIGH OPERATION

With the Front Wiper/Washer Switch in the "HI" position, battery voltage is applied through the WIP Fuse and the "HI" contacts of the Front Wiper/Washer Switch to the "HI" side of the FRONT WIPER MOTOR. Since the FRONT WIPER MOTOR is permanently grounded at G106, the motor operates at high speed as long as the switch remains in this position.
