Josiah,

In an effort to beat this old horse to death, let me try to get straight on this coil idea. What is the purpose of the bypass switch or ballast resistor in the ignition circuit on many of these trucks?

Isn't this an attempt to give the ignition system the benefit of full system voltage when the starter is demanding most of it during a 'start'. Doesn't this say that the more voltage you put into the coil, the more spark energy you are going to get out of it.

I am not an electrical engineer, but I thought this is how it worked.
