to calculate amps the formula is voltage / resistance(ohms) = amps
14.2(output from Alternator) / 3.5 (coil resistance) = 4.05 amps
The Pertronix coil states is has a resistance of 3.0 ohms which would make
the amp draw of 4.7.
The Pertronix Web site does say 4 and 6 cyclinder engines should not exceed
4 amps. I would of thought that if this was the case then they would of designed the coil for a higher resistance instead of adding a ballast resistor.
