I think a 6 volt might work as you describe, but not sure that it will power the meter sufficiently. Note also the difference in polarity...6 volt is postive ground and 12 are neg ground.
Westach apparently does supply 6 volt pos ground tachs.
Let us know if the 12 volt tach works, would solve a problem for lots of us.
