1. Coils can run hotter than you might think, in normal operation... any starting or running problems to go along with the percieved excess heat?

2. Check your charging system voltage... anything much over 14.5 Volts is too high, and may be conributing to the heating up of the ignition coil.

Replace the 6 volt coil and external resistor, or get a 12 volt coil with an internal or external resistor. NAPA has one of those. I don't believe there is a 12 volt coil that does not need the resistor, that's what I have been told. You will burn your points without the resistor, 6 or 12 volt.

Check the voltage comming off the resistor. It should be 6 to 8 volts. The only reason for a coil to get escessively hot is to much voltage, so unless the coil is failing, the resistor is probably the problem. I don;t quite understand all the interest in changing coils at conversion. All relevant coils are 6 volt. they either have a internal resistor or external. If you already have a good 6 volt coil, a ceramic resistor is alot cheaper than a coil. Some systems will run 12 volts to the coil in the crank mode only and revert to 6 volts at RUN to make them start easier in the winter.
