Can you run a 1 wire alternator and still use your idiot light or do you have to run the 3 wire alt? My dad is looking to convert his 56 chevy over to a 1 wire alt but he still wants to use his dash light, is this possible? I know you can do it with the 3 wire but am not sure if there is a way with the 1 wire. Any help is appreciated!:yes:

No idiot light with a one wire.

^^^ Yep, if you want the idiot light, you need to run a 3-wire. That's a good thing because a 3-wire setup is better anyway.

Good reading on the subject for you and your dad:
