Please help me better understand how to test the primary and secondary on a helmet coil.

Even if you bench test it, it may not preform the same under a hot condition.

Thought you had this running well under idle, but was bucking under load?


Intermittent spark on the 1 seems like something with the rotor. Add a additional engine ground. Never enough grounds.
