 Well, not to confuse the issue, but I replaced the OEM battery on a 2011 e=
lantra 10 days ago ...
Installation day off charger new battery was 13.04 volts ..=20
this am (10:00) after setting 10 days read 12.45 voltsstarted/ran 10 minute=
s read 14.5 volts while idle=20
key off=C2=A0 read 13.22 volts2 hours later (12:00) read 12.46 volts ... I =
can measure more (setting off) if you want=20

That 14.5 volts at idle "sounds" high to me, as I've usually read around 13=
.5 volts on an alternator but ....I'm not going to 'fix' it yet

 For the past few weeks I have been fighting a parasitic draw on my BJ8. It=
 was running about .48 amps and would drain my battery in a day or so. I wa=
s told by a mechanic that a diode in my alternator must have blown therefor=
e causing the draw. He also mentioned that my ground wires in the boot were=
 loose which he tightened. I brought the car home, turned off the power in =
the boot and 2 days later the battery was dead.=20

So, here=E2=80=99s what I=E2=80=99ve done. I jumped the battery and started=
 the car and ran it for 10 minutes. I disconnected the charger and tested t=
he battery - 12.48 volts. I then removed the cutoff switch and bolted the g=
rounding wires together. I tested for a draw and got a zero reading. That w=
as last night. I went out this morning (12 hours later) and the battery rea=
ds 12.33 volts.=20

My questions are 1. Is .15 volts a reasonable drop in voltage for a sitting=
 car in 90 degree heat and 2. Can a diode in an alternator work sometimes a=
nd not at others. If it=E2=80=99s either =E2=80=9Cgood or bad=E2=80=9D all =
the time, I guess I need to presume the alternator is not the source of the=
 draw. If a .15 volt loss over 12 hours is reasonable then removing the cut=
 out switch in conjunction with presuming the alternator is good (as it wor=
ks fine now) solved my problem.=20

What does the wisdom of this great resource think?
