Not too good. Proper charging voltage is 13.8 volts. Does it go higher
when the engine is revved?

Subject: voltage over battery: 12.5-13.1

Hey guys,
I've been having some dying battery issues lately.  Anyways, I replaced
my
battery under my autozone warranty.  At an idle, with no headlights or
heaters or anything on, I'm reading something like 13.1V over the
termainals.  Turn on some headlights, the heater fan, and maybe the rear
windshield defroster, and its closer to 12.5V or 12.6V.  Are these
numbers
about right?  The alternator's new (rebuilt) as well, as of just before
christmas.

thanks,
wes
