Hello
I am currently converting my 1965 Vauxhall Viva from positive earth to negative earth and so I checked on my 1970 Fiat 500, which is of course negative earth, to make sure that the new Viva wiring matched the Fiat. However, now I'm confused. On my Fiat, the dark green/dark blue wires attached to the positive terminal on the coil go to a resister and to the distributor while the light green wire from the harness and presumably coming from the ignition goes to the negative terminal. From my research, on a negative earth car, the positive terminal should be attached to the ignition.
So please can someone put me out of my misery and let me know how the ignition coil on a 1970 Fiat 500 should be wired.
Thanks
Mauro
