spark issues

[fiesta54]

Hey so my ignition switch is beginning to go bad. I have already had to bypass the switch for fuel and now I get spark in run but not in crank. I have a 75 124 and was wondering if anyone knew which wire needs to be jumped to fix this? Thanks!

On my '72, terminal #50 is the starter. Should be Red wire in your car.

Thank you! Although I've realized I dont really know what I am doing. I was told to jump the wire to get spark. But I am not sure how to do what and still have the spark stop when I turn the car off. Should I just splice it in to switched power somewhere as a temporary fix?

Some of the wires in the ignition switch are not fused anywhere along their length. An incorrect connection can easily start a fire. If you're not sure of your capabilities to re-wire the Fiat starting system, maybe you'd be better off simply replacing the ignition switch. IAP has an informative video on their site describing this procedure. If a new switch is out of the question, there are probably some salvage yards in the Richmond area containing Spiders. If you are slightly handy, you can "sorta/kinda" rebuild your ignition switch by removing the C-clip and drilling out the rivets holding the thing together. The burned contacts can be scuffed clean, and the switch re-assembled with slender machine screws and nuts.

this is just about the same issue I have on my 75.....power in on position but no fire when cranking.....I'd like to jump switch and just get it running....I'm in central Pennsylvania and these cars are hard to find so salvage yards are most likely not going to have any.....3 years in my shop...it needs too need the sun.....help
