Royce,

Objective was not to just go willy-nilly and change out VRs, gens, etc; but rather to test to see what works and what doesn't.

1 & 2 were results of questions relating to a 650 Ford. My understanding was that there is a measurable reading from ARM to BAT IF the VR is good - if not, then replace. Further, there should not be a measurable reading between ARM and FLD is VR is good - thus replace if get a reading.

In fact, those instructions seemed to have been reliable regarding an 8N and a 650. But, will verify or correct notes at the proper time.


But, no one should take my word for anything. I'm the trainee/learner, not the wizard. Pleased that lots of experts respond to posts such as mine - and try to get me on the "straight and narrow".

Been watching from sidelines, but have a question for you, equeen, when you say, "jump from ARM to BATT", what does that mean? And when you speak of "see a reading" or "see no reading", are you referring to voltage, amperes, or Ohms?

Apologize for my wording/terminology.

I'm actually checking for voltage reading with one probe on the ARM terminal of the VR, the other on the BAT terminal of the VR, etc. Thus, I either see a reading or else see no reading. This is done with the engine running, all wires connected, etc.

I was beginning to suspect that. You see, about most of the population will take "jump from A to B", to mean that you shorted A to B with a jumper wire or a screwdriver or pliers or some other conductive object, rather than that you connected a voltmeter between the terminals, A and B. Clear communications is difficult! Sender & receiver may end up in two different worlds. This I'm afraid makes much of what has been said, null & void.

Thanks for getting me on the right track with my terminology. Yes, I can see that words do make a difference - and my words can get wacky.
