Possible to upgrade mechanical meter to digital ? I have a generator with a ground and positive wire.

This meter, as it states, has a thin wire that you wrap around the outside of the positive wire in your generator. You mount the digital meter wherever you want on the generator (attached by the thin wire). Now you have a digital readout. I find it works just fine.

Will it work on aircraft that has a magneto?

Most outboards and small engines have a magneto, so it should work well.

Use old + and - you upgrade from mechanical to digital meter, how?

Wrap wire around spark plug wire.
