With all this discussion about isolators mine of course is acting up... During a 1200 mile round trip a couple of weeks ago my dash DC meter was variable showing 11.9 - 16.0 volts. Took out alternator and had it tested at my local rebuilder. Checked out okay. Go figure.

Meter from center post to ground with engine @ idle is 14.8 v. Meter either outside post to ground with engine @ idle is 12.8 v.

Is the isolator on the way out?
Thanks
