I have a 67 series V. I have removed the rack and cleaned and lubed it and have done the same to the motor. I have checked my wiring at both the switch and motor numerous times to be sure they are correct. I have a wiring diagram I followed plus I referenced the post from Tom H as he was helping another member in march. My wipers will not work when all the wires are connected. The horn will try to sound when I shut the wiper switch off. I disconnected the (white) wire from the double green connector and ran straight power to it from the battery and the wipers work as they should. The switch will turn off and both speeds operate normally. Why won't it operate from 12 v in the double connector but is just fine with 12v frome the battery? I know the 2nd green wire goes to the brake switch and from there to the horn. Am I getting some kind of feed back?
