Re: Coil resistance wire getting hot

That wire is doing its job right if it's getting hot. It is the [White/Purple/Orange 20] resistance wire that is the power supply to the (+) coil. In a point system, it's necessary to drop the voltage from 12 VDC to 9-7 VDC after first ignition so the points don't burn up.
If you're not using points anymore, you need to bypass this wire and feed the HEI coil from a full power 12 VDC source.
