Almost like the null has moved when running? The farthest down I can get it with ALL loads idling at about 950 is about +7 amps...
Battery cranks it right up.
Anyone had similar issue?

Is this not the reason many have given up on ammeters and replaced them with voltmeters?
"...a voltmeter logically provides far more useful information about alternator system performance compared to the ammeter."

BTW: Does your ammeter have a range sufficient for your alternator (e.g. +100/-100 amp range for 70 amp alternator)? Is ammeter wired with a shunt, or does all current flow through ammeter?
