Pulse

With the Front Pulse Wiper/Washer Switch in PULSE (Delay), a controlled voltage Passes through a resistance is applied to the BRN (96) wire, the Front Wiper Motor and Module and the Solid State Logic Board. Voltage is supplied to the Park/Run Relay Coil which is momentarily grounded by the Solid State Logic circuitry and the relay closes. Battery voltage is supplied through the closed contacts of the relay to run the Wiper Motor. The relay remains energized as long as the contacts of the Park/Run Switch remain closed. When the wiper blades have reached PARK, the Park/Run Switch opens, de-energizing the Park/Run Relay. The wiper blades remain in PARK until the Solid State Logic Board grounds the Park/Relay Coil to start another sweep. The delay time between sweeps is controlled by the pulse delay resistors inside the Front Pulse Wiper/Washer Switch. The delay can be adjusted from 0 to 43 seconds.
