Bud, This is going to sound stupid, but is it a Chevy/GMC? I've seen the voltage too high when the stupid ground strap needed some TLC... Could be a lot of reasons, but start with the simple stuff. Check the battery terminals for corrosion, loose connections, etc... Clean everything up and while you're there... No-Ox/PenetrOX the whole thing... (That's Mr. W0KU's pet peeve that I never did that on anything under the hood. He's made me a believer over the years. He even puts the stuff in the fuse-holders.) Probably worth a stop at any shop to have 'em throw the tester on the battery that tests the whole system under load. You may just be seeing a battery that's headed south, too. (If we're working off the "What changed?" theory. What's the voltage read when the engine is off?) -- Nate Duehr, WY0X n...@natetech.com facebook.com/denverpilot twitter.com/denverpilot
