Wiper and Wiper Arm System Operation


The wiper system operates only when the ignition switch is On or in the Accessory position. The wiper motor has permanent magnet fields, and high and low speeds are determined by current flow to the appropriate set of brushes.

The optional intermittent wiper system, in addition to HI and Low speeds, has a Delay Mode and a Pulse Mode. The Delay Mode, with a delay range of one to fifteen seconds, is controlled by a variable resistor in the wiper switch and two relays. One relay turns the wipers On/Off and the other changes the speed. The Pulse mode allows one or two sweeps of the wiper system at the drivers command. With the switch in either Off or Delay position, a momentary movement of the switch into Wash position will activate Pulse Mode.

The wiper system completes wipe cycle when the switch is turned Off and the blades park in lowest portion of wipe pattern.
