My initial "diagnosis" would be a bad connection somewhere. I'd take apart both battery cables, at both ends, clean them and put them back together. I might also try disconnecting the gauge connections, cleaning them and putting them back together again.
A dancing needle would indicate a poor connection. When at idle (a constant minimal reading) it wouldn't be as apt to show. Start off by looking for the obvious.

Thanks for that Mrfiker...I'll check that 1st as I do all my joints/plugs with elero grease...its started happening after i wash the bike at a car wash...thinking maybe water got in the reg. or alternator plug....can't check it until i get back next Thursday...just wondering if it was a short or not.... it is acting like one....
