Richard,
Are your writing about the ballast resistor or the drive resistor(I
don't think they were used on that early a car)? On Spitfires the ballast
resistor is buried in the wiring harness as a Pink/white wire. If indeed
you do have a problem with the ballast resistor and replace the OEM coil
with an after market, with internal ballast, be sure to by-pass that
pink/white wire with a circuit that will supply 12 v. to the "+" coil
connection during cranking as well as normal running. What make and kind
of coil are they selling you? Just make sure it is internally ballasted
(3-4 ohms across the two primary terminals).
Hope that helps,
Charlie B.
