" he is sending a message electricity is mysterious to him and he knows little about it."

Electricity is a bit of a mystery, even to physicists; but I think that I have a reasonable working knowledge. For the record, so did the professors who saw fit to graduate me, Cum Laude, from Cal Poly San Luis Obispo, which is one of the better engineering schools in the nation.

I worked my way through college wrenching on cars, and I was known as the "go to" guy for electrical problems in each of the three shops where I worked as I went through school.

I don't recall ever owning a VOM that would carry enough amperes be useful in diagnosing a current drain in a car without blowing its internal fuse, and clamp-on ammeters would not be sensitive enough. A 0.1 amp drain or a 2 amp drain are the same thing to me. They are both unacceptable. The only difference is time-to-dead-battery. A voltmeter works just fine for locating a current drain.
