RE: [DML] Re: Replacement MSD Coil

["John Hervey" <john@xxxx>]

Bill, Keep in mind. We talk about 12 volts, but when the car is setting the
battery should be 12.6 volts and running should be around 14.4 volts by the
regulator. The only time we would see 12 volts would be ign off and a weak
battery or when running and the voltage drops because of lights on or
something like that. That's why sometimes a dropping resistor may be used.
14.4 down to 10+.
John

I think he meant $50 for coil and resistor as package (still pricey
compared to mail order, but storefront retailer does have overhead).

NOTE: resistor is for ignition module's benefit, not coil. In fact
these high voltage coils are designed for max performance with 12v
ignitions (will work with OEM's at slightly lower output). Unless
you've upgraded factory ECU, make sure replacement resistor rated
comparably. Otherwise you'll cook ECU.
