Actually, I meant it as one careful test - to do all those measurements
using one ground.  You can reach anywhere you want with a longer wire.
Shifting ground points to places near the voltage test point may mask
poor ground continuities... say, between the battery and engine
compartment, for instance.

Um, yeah, ok.  Just don't call your EFI computer a "Huwlett Packard," ok?

Oh, and make sure the EFI gets power in "start" as well as "run," of course.
