Gregory,
I looking over the wiring diagrams for early car and can see the ballast
resistor wire listed. It appears in 77 Triumph went to 12 fuses with
some air-conditioned cars in some markets. Can't see a resistor wire
in any circuit. However, it does show a 6 volt coil which means voltage
has to be reduced somewhere. There is an item listed as a Drive
Resistor
coming off one side of the distributor, maybe this is it?
Hope this helps more that it confuses.
