I would like to run a few more tests as I try to get my head around all this.

The calculations are clear and would seem to point me in the direction of adding a ballast resister (1.5 ohm) in front of the coil+ in order to reduce incoming volts to the coil.

In my case we have:

14.04V / 3.0 ohms = 4.68 amps (or 13.0V / 3.0 ohms = 4.33 amps in the best case scenario).

Both of these values are outside of the acceptable range. Adding 1.5 ohms resistance would give us:

14.04V / 4.5 ohms = 3.12 amps

I assume this would also mean running a wire from the starter+ to the coil+ to have full battery volts while cranking?

And all this begs the question: why are the volts measured at the coil+ too high in my basic installation? Is this not the case for everyone?? If we reverse the formula for a circuit with 3.0 ohm resistance at the coil and 4 amps maximum desired at the coil+ we get 12V maximum. Any time you charge the battery you're going to exceed this value.

This would also mean that the condition has existed "forever"?

Are we chasing fireflies here?
