That was going to be my "fall back" plan... and I may still do it,
depending on the readings I get from the Plug in Voltmeter. Reason for
the plug in unit was to have something I could leave in the plane and
monitor over the course of several flights.

Unit is on its way to Michigan from "Auto Barn" in New York. Couldn't
find one at several Auto Specialty shops locally.

If you already have a good DMM, do what I did--

Go to Wal-Mart and buy a cigarette lighter plug for $0.99. Strip the leads
and clip to your DMM. Start your motor and go.

With my Fluke 87A, I could even trap voltage spikes on the system.
