View Full Version : battery issue

I put a new battery in at the beginning of the season, yes, it was a Walmart battery but I have used them in other vehicles and they have been good to me. However, in my stang, it seems as though the battery loses it's charge if I let the car sit for 2 days. Could it be getting drained from the pulleys that I have on the car or what? Walmart will replace it free so that is no big deal. Just curious how long your batteries last.
NO CHANCE

You may have a draw. Or the pulleys could be a factor. We nned some more info, where is the batt mounted, what alt do you have, what accessories, etc.

Could have a draw on it, or could be a bad battery if Walmart will replace it free thats a easy thing to try. Even if your altenator wasnt charging fully the battery should regain some of the charge when sitting, so I would rule out your pullies. :thumbs_up

If you don't drive the car very often, and when you do, it's only short trips, the battery might not be fully charged. Have you tried having it charged?
It it's not too much of a hassle for you, disconect the battery right after the last time you drive it for a few days. If you find it never goes dead as long as you are disconnecting it between drives, then you have a draw when the car is sitting. If it loses it's charge even when it are leaving it disconnected, then you do have charging issues or the battery itself is no good for some reason. Wal-Mart batteries are probably made by Johnson Controls down in Glendale anyway, those aren't bad batteries.
If you have an ammeter, you connect it between the positive cable and the positive terminal to see if there is a draw. If you find a draw, you can start pulling fuses until the draw goes away, then trace that circuit for the problem.
Trivia: Made by Exide. The truck stops at Wal-Mart after they leave our store.

Charge up the battery overnight and have it load tested the next day. If it passes a load test, then hook up a voltmeter and see what your readings are before and after you start the car.. Voltage should go up a couple volts when car is running. If all this is well, then you have a draw somewhere and you need to go the ammeter route.

I think I tested Wayne's charging system several months ago, it was charging at that time... This was last spring though...

You never know,, maybe that battery was sitting on the shelf for a long time or maybe just a bad one altogether...
Disconect the battery and put your ohm meter between the postive and negitive cable. If it is anything but open (milliohms don't count) you have a drain somewhere. BTW, have you every replaced the infamous alternator connector? Also, the signal (white) wire on that same infamous connector is also known for breaking where is goes up and over the strut tower on the passenger side.
You would know right away by your volt meter in your car if it wasn't charging though.
Pull the fuse for your dome light if you do the ohmmeter in line.

Wayne,
My 91 started doing that same thing when I had it. My fix was to sell it and buy an 03 Cobra.
j/k Actually, my alternator was weak, so I just replaced that and then everything was fine.

:thumbs_up I say you just give up and sell me the car for a dollar!

Couldn't you just close the door?

Yes, but when you open the door to pull fuses to track the drain down, POP!
