resister required for a replacement coil I bought an Accel 8140 Super Stock coil to replace what looked like the original coil on my '57. Good coil, I'm sure, but the package says nothing about an external resistor. Back in the day, coils came with a notice indicating that it did or didn't require one. I even went to the Accel homepage and still nothing. The original 57 uses one of course. Can anyone shed some light on this? Thanks.

Re: resister required for a replacement coil If I was in dought I would use a resistor. Can't hurt coil with resistor but, without it could fry the coil.

Re: resister required for a replacement coil It's not the coil so much as the points if you're still running them. I would use the resistor. With points or a Pertronix system, a resistor should be used.

Re: resister required for a replacement coil it needs a resistor, 1.35 ohm in the line to the coil, if the coil is getting around 9v to the coil after the resistor your fine

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....... |
Re: resister required for a replacement coil Thanks for the info guys. It makes sense. i checked the coil's primary resistance in the online description and sure enough it was 1.2 ohms. I will pickup a new resistor to go with the coil. Thanks again.
