Did you check your alternator?

wason

Yes alt is good

Doesn't sound like it is to me! Are you sure your grounds are connected and tight? How are you sure the alternator is working correctly? Just because its showing that its charging doesn't always mean its good.

Being that you've been driving it like this for a year, if I were you I'd just replace the battery and alternator then double check all the connections at both ends. Your lucky you made it this long without frying the computer.

If all that doesn't work then it could be possible that you DID fry the computer. In these Jeeps the computer is the regulator for the alternator. If its not regulating correctly you'll keep cooking batteries and alternators.

I took it to sears and the put the machine to it and they said the alt and battery was good

intermittent short in alternator--original equipment? an alternator can have an intermittent short-and sometimes it wont show up till ya test it several times--cuz it dont sound like a draw

kjc

So you drove it to sears and they said alt & battery were ok. Problem solved?

wason

Nope still doing the same thing

wason

If the car stay stop for a full day it drain the battery

Do you have a sound system hooked up? Maybe an amp that doesn't have its remote wire set up proper?

can try a test light between positive cable and battery and have a friend remove all fuses, one at a time. When the test light goes out, you know which circuit is causing the issues.

wason

I check all my lights, hood light, glove compartment light, check the starter disconnected all the lights under the dash and still the same problem

GI-Jeepin'

Ok, so you checked your lights. But have you used a test light at the battery to see if you have a short somewhere?

wason

I will do that and let u know thanks

wason

I took the positive cable and put the test light and is coming on tomorrow I will start taking fuses out
