High-Speed Operation

In the HIGH position, the wiper switch applies full voltage on CKT 92 (PPL) to the wiper motor. This voltage applies to the motor's high speed winding. The HIGH speed position also closes contacts in order to apply the low-speed voltage to the motor on CKT 96 (BRN). This voltage allows the solid state logic to complete the wipe cycle when the switch is in the OFF position. Without this, the wiper blades could stay in mid-wipe when the switch is in the OFF position. The solid state logic also applies voltage to the motor's low speed winding. This has no effect while the high speed winding is operating.
