Default Ignition Coil

The original coil in my car is getting quite warm/hot. Everything seems ok, but since it's the original... I'm looking for suggestions on a replacement. It's an external resistor.

I believe that Rick at SS has new ones.

I recently bought a Lucas DLB102. I needed a 1.5 ohm coil since I have the ballast resistor.

The Lucas 101 can also be used which would require not using the external resistor since this coil has an internal resistor. You have two options.

If you leave the ignition on while fumbling around, they can get quite warm!

If the resistor is a large wattage resistor (putting out a lot of heat), WHY would one put it inside the coil? That does not make sense.

Lucas and other companies have made a coil with an internal resistor. Check the SS catalog and you'll find that the coil he sells has an internal resistor.

When they say "internal" resistor coil, it is a misnomer.

What the coil actually is is a coil with higher primary resistance (more primary turns) so that the peak coil current is acceptable without the external ballast.

Ah yes, that makes sense.
Then the engine can't benefit from a hotter spark by bypassing the load resistor at start-up.

The main thing is that it works and the car runs. If the instructions say remove the external resistor then do it. If it says retain the resistor then keep it. Why worry about what is inside? These are Alpines and they will break so carry spares. Jan, what series of Alpine are you now driving?
