Stop in for a cup of coffee

Makes sense. Might have to open some of my old electronics books for this one to re learn some of what I forgot! Dam good question though, and if so why are not racers using them? I know the different coils need a different voltage drop but past that need to look up the theory again.

I think they are, they just don't know it. LOL

I think the other thing is matching the primary resistance in the coil with the ballast resistor so combined enough power flows through the coil to induce the secondary power needed. But too much excess and it just generates heat.
