videos | at work | information | view | construction
In this video Jeremy and I will discuss how to diagnose if it's your battery or your alternator that is giving you problems, the correct voltage of your cars battery with the key off and at idle. We also discuss possible causes of vehicle that seems bogged down. And then what to keep your eyes out for in a junkyard.

i have a digital volt meter always connected to my car, sometimes when i let of the throttle it drops to 11.3 to 11.9v for about 3 sec or if i hit the throttle quickly goes back to 13.9 to 14.2 v. brushes or battery?

I have an 8.1Ltr/496 on my Suburban with a 120v Alternator. My brushes wore out and my auto parts store doesn't carry brushes for Delphi/AC Delco... so, I called AC Delco and they told me that they don't sell brushes ($2.00 part) and that I would have to buy a whole new alternator ($300.00) Anyway, is there an alternator that I can buy that has service parts, or is there someplace I don't know about that has aftermarket service parts. (Like JEGS...) Where would I get brushes for my alternator?

I buy a new alternator but my car want stay running

2002 BMW 330CI... I had an issue where the car would die when it had been running for a bit. Bad Alternator, right? I mean, if the Alternator was working, why woukld the car die after 1/2 hour. Had battery tested at AutoZone, they said OK... Slam-Dunk - Alternator right?
Well, after going through 3 alternators, cleaning all grounds and connections... a new Battery solved my problem! Why???? I am confused.
The only thought I have is that the battery would not come up to full charge, and the alternators overheated trying to get it up to full charge, and after overheating would not provide voltage.
On the current alternator (thankfully under lifetime warranty) as the car started getting funky (symptoms started with airbag light, then brake light, then other warning lights) I put a meter to it, and the voltage was 14.4, then dropped to ZERO and fluctuated, then back to 14.4, then went crazy again.
Out of Ideas, I put a new battery in, and 100 miles later, no issues, no lights, always steady 14.4 volts...
I bet I never had an alternator issue. What I learned is to also have your alternator tested before assumint it is bad.
My question is, how can a bad battery cause a running car to die? -
hey anyone reading. my 4.0 Cherokees voltage drops from 12.8 at idle to 12.3 when I use my blower fan. what is the lowest the voltage should go? seems even at 12.3 its still dropping.
