WASH/WIPEF5 CIRCUIT OPERATION1 CIRCUIT OPERATION Front Wipers 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 its operation. Rear Wiper Intermittent Operation When the rear wiper stalk is moved to the ªonº position, then the rear wiper will perform two complete wipes and stop in the park position. Afterthat, its operation will vary depending on the selected mode of the front wipers. Reverse Gear Wiping If reverse gear is selected while auxiliary or ignition is on and a front wiper function is selected, then the rear wiper will operate as well. If reverse gear is selected while the front wipers are off (or performing a wash/wipe cycle) then the rear wiper will operate in the mode indicated by the rear wiper switch. Rear Screen Programmed Wash/Wipe If the rear wash/wipe switch is operated, the rear screen wash motor will operate for 1.5 seconds or for as long as the switch is held on, whichever is the longer. The rear wipe will be operated 0.5 seconds after the switch closed and will continue to operate until three full wipes have been completed after the washer motor has ceased its operation. Wiper Operation With Speed Dependency On If the vehicle has speed dependent wipers, the wiper adapts its speed to the vehicle speed. The speed barrier, where the wipers move between a faster or slower operation, is 2 mph. Headlight Wash/Wipe If the headlight switch is in the on position, the first and every alternate operation of the front screen wash switch will activate the headlight wash/wipe motor, which will operate for 2 seconds, regardless of the length of time the switch is pressed.
