[DML] Re: Battery condition

["Bernie" <bmanderville@xxxxxxxxxxx>]

A fully charged battery should acutally read about 13.5 volts.  Take
the battery and have it tested.  You alternator voltage at about 2K
RPMS should be about 13.5-14.5 volts.  Check your grounds and
alternator positive connections for corrosion, as well as your starter.
