Update, charged battery to 12.56 put it back in and it gave a slow crank sound then stopped. Checked voltage and it was now at 11.96 V. Decided to jump it and IT STARTED. Brought it home its sitting in driveway running volt meter showing 13.7V. Now could it still be bad battery and mechanic at walmart does not know how to use his tester??. Not K40 ...Now what???
