'71 Duster 340 Battery getting overcharged

12.38V...all connections cleaned up. I have a new VR...should I do the same check with it? Don't know if I'll fry it. It looks like there's 12+V coming to the blue wire with the ignition switch on, but engine off. V is 0 at the blue field on the alt with the VR cap on and 0 at the VR blue wire cap with ignition off. I'll go re-read your last couple posts and double ,double check readings again.
