Hey all,
I went and had the battery charged, and it held just fine. We put it in the car, and it with it running, tests at 13.8 volts. Hmmmmm...... I come back, 2 days later, I'm pushing a whopping 10.2 volts. Methinks my newer alternator sucks. I'm taking it off and taking it over to Autozone to have it bench tested.
I have a question though. How do you remove the lower bracket bolt that the Alternator swivels from? Is it a hex head key? Or what size socket do I need to use? I can remove the top one with a 1/2 inch socket (yeah, it's aftermarket) but I am having a hard time firguring out what to use to remove the bottom bracket.
Thanks for your help,
Chris

Also, This pretty much tells me that the problem is in the alternator, right?

The lower bolt is a 6mm hex...maybe 8. I'm pretty sure it's 6 though; I'm always grabbing for that one it seems.
I'm not sure it's the alt. There are lotsa ways you can drain...you sayin' it was draining from driving? How much driving had you done between 13 and 10 volts? A fully charged battery can get about 60 miles without an alt if you're running only the bare necessities. At that point you're looking at just over 9 volts once the car stops running.

Less than 60 miles but close. I'm taking it to have the Alt. tested tonight.

Yeah, if you were driving that far and came up with that reading....sounds like your alt isn't doing anything at all

No, this is good news. I'd rather I know what it is that's wrong then have to hunt down a nasty little gremlin.

If it is any help, I upgraded the stock puny wires that run from the alternator to the starter and then from the starter to the battery. I don't know if this is your problem, but it will definitely aid in the charging of your electrical system. I just used some really large car audio cable with a high strand count and it really did wonders.

So true....nothing like a nice hidden short to waste 25 hours of your time looking for it!

Re: Update on charging issue.....or lack thereof. (PAGTI91)

Hate to rain on ya, but I just read this while looking at some stuff....
"I
bought the BOSCH rebuild alt form my local dealer, after I installed it
in my car I thought everything will be fine, but after few days my car
battery sign lited up, after that I took my car to have the charge system
checked and the result was my alt not putting enough charge to the
battery. I checked the voltage when the car at idle and everythings off, it
was barely 13.0v, if the everythings ON and in stop'n'go traffic it only
about 10.7. After a week I took my car to my another mechanic to check
the alt, they pulled out the alt and sent to a alt shop to test it, the
result is the alt not putting out enough amp. At the same day I took
that alt to change it form dealer. This time was my mechanic put it on,
it coasted me $90 labour!, after installed it the output increase but
still can not hold the battery charge, it about 12.0v-11.8v on loaded, when
encounter the stop'n'go traffic. The only thing I can do is no stereo, no A/C
or sometims even turn the hedalights off, because I don't want my battery goes
down to 10-11v while I'm driving. Well, I'm now leave this problem alone
because I really don't know how to deal with it. May be the $350 one is
the real thing huh !"
Sounded similar to your problem, but no fix posted

Re: Update on charging issue.....or lack thereof. (Tornado Wolfie)

Damn! This sucks. I will have the Alt. tested to verify that it either is or isn't my alternator.
Hopefully some of these guys will catch it and be able to help.
I will post updates tomorrow.
