Wiper, Front

WASH/WIPE

CIRCUIT OPERATION

The front wipers will only operate with auxiliary or ignition on, except when auxiliary and ignition are both turned off, the wipers will continue to operate until they reach the park position. If the engine is cranked while the wipers are on, then the wiper operation will be suspended until cranking is released.

Flick Wipe Operation
When the flick wipe switch is operated, the wiper will operate in the slow wipe mode until the switch is released.

Intermittent Operation
When the wiper control stalk is moved to the intermittent position, the wipers will perform one wipe of the screen at slow speed and then wait for N seconds before doing another wipe etc. The value of N is determined by the position of the wipe delay potentiometer. When the potentiometer is in the far left position the time delay is 2 seconds. Each movement of the potentiometer to the right doubles the time delay, up to a maximum of 32 seconds.

Slow Speed Operation
When the wiper control stalk is moved to the slow position, the wipers will operate continuously at slow speed.

Fast Speed Operation
When the wiper control stalk is moved to the fast position, the wipers will start operating at fast speed immediately and will continue to do so until fast speed is switched off.

Front Screen Programmed Wash/Wipe
If the wash/wipe switch is operated, the front screen wash motor will operate for 1.5 seconds or for the duration the switch is held on, whichever is the longer.

The slow front wipe will be operated for 0.5 seconds after the switch is closed and will continue to operate until three full wipes have been completed after the wash motor has ceased it's operation.
