Hello, I believe this charge is called a surface charge. Turn your
headlights on for 2 minutes to burn this off and to get your true
voltage.Maybe you have a diode out in the altenator and you are only
getting a lower voltage for charging.Maybe a voltage regulator.Doesnt sound
like a shortcircut that is draining the battery. If you think this is the
problem, just remove one fuse at a time and see if the drain quits.Put one
multi meter lead on each side of the fuse holder where you removed the
fuse.If you got current, you got a short in one of the accessories that
this fuse serves.Thisaccessorys still drawing current even though the
switch is turned off.Dont think this is the problem though.
