Universal Ignition switch

Post by dulcimerbob »

The switch on my 76 is faulty so I am going to attempt to rebuid it using the Miafori article. As a back up ( as in if I screw up) I may use a universal switch from Autozone. I am out of Fiat money for a repop switch. Could anyone tell me how to wire it up? I plan to put it in the cig lighter spot if I decide to use it. Thanks

There are links on the top of Chris' page showing the pinouts and colors of the ignition switch wires.

Basically:

#50 starter
#30 and #30/1 ignition power in
#15/54 ignition
INT coil

You'll have to translate these functions to your "universal" Autozone switch pins. I hope you can successfully refurbish your Fiat switch, as the column lock is the only theft-deterrent these cars contain. Let us know how you make out, and share your experience and tips.

I got the switch out and rebuilt . Have not wired it up yet. The job was fairly straightforward per the miafiori site. My switch was a little different than his so i had to improvise. His idea to grind the small nuts to get the circlip back on is correct. Grind them almost half in two just remember to keep the threads intact. All in all a great article. I'll let you know as to whether it works.

I beleive I found a better method for use of the screws. I used screws with a tapered head. I counter-sank the holes so that heads came out totally flush and the circlip cleared with no problems. The end of the screw with the nut fit into the back of the metal cylinder.
