I know when I first changed it it was like 14.4 then 30 miles later at next Oreillys I tested it. It was at 13.6 then drove 1000 miles back to Ohio like that.
I was driving and my battery light popped on so pulled into Oreillys.they tested it and was bad so changed it with new one. Originally I when I first installed I put the power wire on I did the wire then washer then nut. So the guy came out to test battery and alternator and said wasn't working...
