coil issues

Possible causes for overheating: Age wrong wiring. Wrong coil

Whatever the cause - you have a problem

If you are running a 12V car, then ya need a 12 V coil.

Two 12V options - one that needs a resistor wire and one that does not.

The resistor wire is to prevent burining out the points by running a full

Another option is an external resistor instead of a pink resistor wire.

There is a terminal on many ignition solenoids that runs allows you to run a separate wire to te coil providing full 12 V for a hotter spark while teh engine is cranking.

Are you running a bone stock setup or has it been "improved" over the years?

It's absolutely stock, as far as I know. I just bought a coil a few months ago - wonder if it's the wrong one. And I sure don't see an external resistor anywhere.

It might have a resistor wire. Check the voltage at the plus terminal. Should be 9 or less. What are the symtoms that make you think it is the coil?

If I can poke in with a question here...

I'm getting a new wiring harness for my '63 Lark from Studebakers West, and they told me that I would need an external resistor since the proper resistance wire isn't available. So, what kind of resistor do I need and where should it be inserted in the circuit?

The coil bracket should have a provision for a screw to hold the resistor. Any generic ceramic resistor should work. They are rectangular in shape, white color with contacts on each end and a hole in the middle to accommodate the screw that fastens it to the coil bracket.
