Question: Do I need to use a resistor with the coil? It looks like voltage through resistor is bypassed when starting. How do you accomplish this with the foot starter? I've seen foot starter switches with a side lug, is that what it's for?

If I were to use a coil with an internal resistor, how would I get "full voltage" to the coil when starting. I don't see how this would be possible.

the reason the bypass is used is so the coil gets as much "current" as possible when the starter is loading the battery heavily - if everything's tickety it'll fire even tho there's not as fat a spark with the resistance in the circuit
