I've been frustrated the past 2 days dealing with electrical on a Farmall 100. Ammeter on tractor seemed fine with only a little bounce. But, my digital VOMs bounced all over the place so fast I often could just glimple the numbers. Had changed VRs because I "thought" the first was bad, had genny checked by genny guy, checked all grounds, new wires, new battery etc. But, still digital bounce, so I wouldn't run the tractor but a few minutes for fear of burning something up.
Finally went out this AM and found a nice analog with large scale for my old eyes. Priced right, too.
That sucker is great! Smoothes out the bounce and I can see what's going on. 6.3v engine off; 6.8v engine running; 10.0 amps at ammeter. Lights work "and all". Maybe I'm too happy.
Anyway, thanks to all the old timers who have kept talking about analog meters on lots of "electrical" threads. I am now a true believer. AMEN and AMEN!
