Default Re: resister required for a replacement coil

Your system (assuming its a point type distributor) requires 3-4 ohms of primary resistance to prevent burning the points up with excessive amps.
So a 1.5 ohm resistor and a 1.5 ohm coil would be 3.0 ohms, and when hot more toward 3.5-4 ohms..... 4 ohms would be 3 amps (where you need to be) and have a good life with the contacts.......
