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. |

update...
I got the wipers to start working.. not sure how, but it occurred after I had the battery on charge and whilst it was still connected to the charger. The wipers started to move ever so slowly.... when I pulled them off the screen, they seemed to work fine in mid air. Low speed, high speed and the park function. The next night I came down to have a play with the car... the fuse blew again. I couldn't understand why... I thought I had it all sussed. A friend came over, and had a look at some wiring and we could see that there were new terminals plugged into the harness where the wiper motor was.... So I proceeded to remove the tank... Once out, I could easily see the wiring... here is a photo... (IMG:http://www.914world.com/bbs2/uploads_offsite/i1260.photobucket.com-18462-1427659080.1.jpg) And here is one of the wiper motor.... (IMG:http://www.914world.com/bbs2/uploads_offsite/i1260.photobucket.com-18462-1427659080.2.jpg) I'm no expert but I did have the haynes... there was one spare wire hanging which I was certain should have been attached to the ground tab on the motor.. also, my motor doesn't have the white block of terminals like most research shows... has a harness that comes from the motor itself.. I am guessing this is a replacement motor. |
