I have an Accel points eliminator with an 8140C coil. Based on my instructions, this configuration does not use a Ballast resistor, because the 8140 & 8140C have a 1.4 Ohm internal resistance. I wired it up and it seems to work/run fine. My only concern is the coil is warm to the touch, bordering on hot. How hot is too hot? Randal

Warm to the touch is not a problem. It actually should get pretty warm, there's a lot of voltage and voltage creates heat. If you start melting the thing, then I would consider adding the external resistor.-Scott

Having said that, some ignition setups can "get by" without a resistor, because some ignitions LIMIT current in themselves. One example is conversions using a GM HEI module. I successfully use a factory Mopar coil on my Dart with an HEI module, no resistor.
No CD type (MSD CDI) needs a resistor, because in those cases, there is no DC battery current through the coil.Last edited by 440roadrunner; 03-08-2017, 10:27 AM.

On the first page that you linked to, shows that the 8140 doesn't need a resistor. Only coils less then 1.5 Ohms need resistors for any points eliminators on a V8 engine. It was carved in stone in the 70s & 80s.On behalf of every manufacturer, delivery drivers, supply chain representatives, and workers of the world, "We're Sorry."
