With Pulse

With the Wiper/Washer Switch in PULSE (Delay), Voltage is applied to the BRN (96) wire, the Wiper Motor Module and the Solid-State Control Board. Voltage is supplied to the Park/Run Relay Coil which is momentarily grounded by the Pulse/Speed/Wash Control circuit 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 Control Board grounds the Park/Relay Coil to start another sweep. The delay time between sweeps Is controlled by the pulse delay resistors. The delay can be adjusted from 0 to 43 seconds.
