OK here's the latest with overcharging alternator. I took it off and down to NAPPA- they tested it and said it was bad- don't ask me- the machine lit up and said "BAD". So replaced it with a new single wire- one wire alternator. Naturally they wern't exactly alike-had to buy a new bely, rig a new bracket- BUT ANYWAY- when I got it on with engine running VOM said 16 volts -down from 17 volts with the old bad" alternator.
Atomarc: I measured amperage with my VOM meter in series with the alternator output terminal.
