In addition, does the noise be actually a "Noise" where it's sparky in
sound, and the level of "Sparkyness" changes with the speed of the
engine, or does it actually have a tone to it. That changes in pitch as
the rpm of the engine changes.
The Sparkyness is from the plugs and wires, the tone is from the
alternator.
