TBM - apologies - my electrical knowledge is limited. If there is a ballast resistor in the system, then should the feed wire to the coil always have the reduced voltage?
The reason for asking about whether a +8 loom contains a ballast resistor/loom resistance wiring is that, according to the Mallory installation instructions, my car is wired assuming that fitment. If there is not a ballast resistor/resistance wiring already present, then my car is definitely wired incorrectly. Hopefully someone can give us the definitive answer....but in the meantime, I'll check the feed wire voltage piece.
