Alan,
Many 12V cars (also AH's and Midgets) have been changed to 6V coil with 
balast resistor for better starting. My comment was meant as a general 
warning.
Lately I have seen several electronic units been fried, one Pertronics, 
one Optronic and 3 or 4 Magnetronics. All had the wire to the starter 
relais to short the resistor in place, which meant that during starting 
the total resistance was about 1,5 Ohm instead of the 3 Ohms that is 
generaly required, thus possible frying of the ignition module.
