Default Re: FSI distributor issue

Looks good Josh, and the wiring shown is correct. The terminal farthest from the wire exit point on the dizzy body is the positive, and is connected along with the 12volts to the plus side of the coil. The connection closest to the dizzy wires exit point goes to the negative side of the coil. It is a good idea to run a good ground to the case, but not essential. The coil should be a 12volt unit with internal resistor, and will measure 3 ohms or greater. This combo will supply you with a hot spark that will jump almost an inch.

I tried running Elvira on 6v with this setup, and it does run, but the spark is very weak, so no dice for 6v cars. It would only jump about 1/8th of an inch. Perhaps a different coil would allow operation on 6v, but the lower resistance primary winding might be really hard on the electronic module. Or, maybe not, no way to know except try it. Since the electronic module is isolated, this could be used with a positive ground system.

If you go with the Honda dizzy, I think you will like it.
