Alternator and Ignition help needed.

Disagree Bill. I think the reason "they" got on wide plug gaps was to help smog numbers. (Back in the mid 70's) Running wider gaps WHEN NOT NEEDED puts a lot of stress on wires, cap, rotor, and other HV components. The wider the gap (or leaner) the higher the secondary voltage goes. And with other external factors like moisture, dirt, etc, at some point it will flash over and or carbon track, or "punch through."
