My new to me, 1970 914/4, has some iffy electrics..
The fuse in the number 7 spot, keeps blowing as soon as I turn the key to ignition on. So, this means I dont have any indicators or wipers working.. etc. Electrics are a little mysterious to me to be honest.. I do have a multimeter.. but I am not sure how to track this problem. I'm thinking I have a short somewhere on one of those systems.. Should I start by trying to unplug each and every component that uses that circuit, then reinstall another fuse, and turn the ignition on? How would an experienced auto electrician pinpoint a problem like this? Any and all advice appreciated.. Cheers Mike. |

Sounds like the wiper motor (there is just one). I doubt it is shorted out. Instead, it's probably the shaft and arm assembly. After 40 something years, the grease inside the frame is hard and the two wiper shafts get stuck. Then you turn the switch on, the motor pulls too much juice trying to move the wipers and the fuse pops. The quick and dirty way is to spray WD-40 or some other lubricant down the shafts from the cowl areA. The correct way is to pull the tank, the fresh air box (which will probably need attention too), remove the wiper assembly/motor, disassemble, lubricate, reassemble and reinstall.
Search the forum, this has been discussed many times. There may even be a classic forum thread with pictures. |
