I'm not so sure that the gauge is designed to give us a linear read out except at the extreme edges of the sweep....kind of like our oil & water temp gauges if ya know what I mean??? What I'm trying to say is that the volt gauge should not be relied upon for any diagnostic in the micro sense.....it's purely a macro reading....if it don't move at all or if it gets pegged there is something wrong for sure, anything in the swept area is only an approximate volt reading.
