Gen1 Diesel General Discussion
My 2014 diesel has 29k & original owner, and today i scrolled thru the battery volts for the first time. It read 12.2 running. I thought that was very low. Usually a parked car reads 11.9 - 12.0, and all my GM cars read up to 14.6 when running. Is this normal, or is the battery or alternator...
