My son's 1996 Jeep Grand Cherokee's battery keeps loosing a charge.?

We're replaced the battery. His glove box was messed up but we also replaced that so the light isn't on constantly. But it still goes dead if he doesn't drive it constantly...meaning at least twice a day or more. Can anyone help us with a suggestion what we might try to remedy this situation? Thank you.
 
Simple.

No worries, it's a relatively small issue.

Judging by your question i would surely say that the fault lies in your alternator.

It's a '96 meaning to say that the alternator has either been changed once or not at all.

1. Get your alternator check or replaced if necessary.

2. If cost is the issue get it refurbish.

Do not be fooled by the mechanic if they says its no serviceable.

Open the alternator up and have the coils and contact points cleaned. Preferably a solvent base cleaner.

All alternators has this "magnet" ring to it. Through the years it might have lost it's conductivity. This "magnet" MUST be replaced.
As for the coils and connecting points, it can be cleaned of of it's carbon and dirt deposits.


P.S From where i come from, its more cost effective in servicng the alternator than buying a new one.

Best Answer?
 
sounds like something is left on after ignition off. Remove glove box bulb and try it, make sure all doors are properly closed. Remove under hood bulb and try that too. Also make sure if any modifications were made to the electrical system. If this don't work let me know by e-mail and I can help you further
 
Assuming that you did not get a bad, new battery, You need to take take off the battery cable and connect an amp meter between the battery terminal and the cable . It should show if there is a large drain on the battery when the car is not running. You would then pull fuses until the large drop stops. Then you know what circuit is the culprit. Remember that the clock and radio and others may draw minor amounts, but you are looking for a big one. It is also possible that the rectifier in the alternator has burned out and electricity is leaking back through it (no fuse).
Eventually you should be able to find the problem and fix it.
