Hey guys, anyone has info on this issue? I searched the forum but did not get any info that was similar, I had my alternator and battery changed by the dealer two years ago, and had to replace the battery again two months ago with one from Advance Auto. I noticed this morning test #9 shows the voltage varying from 11V to 13.7V, when I turned off the engine it went straight to 10.6V any suggestions?
