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. |

You have a dash mounted wiper switch (or HAD one)? I'm not familiar with that setup (is it stock on some cars)?
Brake lights: yes, clean all connections at the light thoroughly. If one side is working, it's probably just poor connections. Reverse light: do you have a reverse light switch in the tranny and is it connected? Also, just like brake lights, clean those connections. Right now it sounds like things have been modified / messed with, so it's hard to give you solid advice or tell you anything about your wiper motors. What you can do for the wipers is (probably with some help), test to see if your wiper motor is getting power. If you can access one of the wires (I believe green/white) at the motor see if it's getting any voltage when you turn the switch / knob (or whatever you have). Maybe take and post a picture or two? |
