Question What's The Matter?

I need help!

I was driving down the road and i heard a BEEP BEEP BEEP. I looked at my guages and the battey guage went below 9 and my CHECK GUAGES light came on. I smelled something, kinda like it was burning. I pulled to the side of the road, turned it off, and looked under the hood and didn't see anything wrong. So i started it back up and went on my way. About half a mile or so it did it again. Then the battery guage started going back and forth between below 9 and 14. A few minutes later when i was driving home it did it again; i had my lights and radio on this time because it was dark. When it did it my lights all dimmed down and then went back to normal.

I think it might be the alternator or battery. But i still would like a better answer.

Thanks

I am not a mechanic by any means, but if you hare smelling burning electrical, you should check all your wire harnesses for anything that looks melted or crusty. might have a short somewhere. Check the wires for any stereo mods you may have done under the carpet also. Good luck.

IMO it´s the alternator. If it wa sthe battery the battery gauge would be at 9V all the time.

Do you have a volt meter with that you can measure how much V you have at the battery poles.

How much V are at the poles when the engine is off? How much is it when the stock gauge goes down to 9V?

If you measure still +12V at the battery you have a damaged alternator.

Installing a new one takes about an hour.

I did check it with my volt meter and it all showed up alright. I couldn't get it to do what it was doing while i was driving though.

X-2 on the altenator. Sounds like the regulator is going bad. THen again you could have a short.

The Voltage Regulator on a TJ is separate from the alternator, I believe the computer takes care of regulating the voltage.

I would bet on a short circuit or a loose contact somewhere.

+1...could even be inside the Alternator...(going for the combo answer)

But if you smell burning its generally bad....and needs to be found before you turn the jeep into a bar-b-q pit.

I posted this problem a while back. I found on my 2005 4banger the wiring harness which is run between the battery and exhaust manifold was melting due to the heat from the manifold. took some tyraps and pulled it away closer to the battery and secured it. To me this would be a common problem if all 4bangers are wired this way.

I took it to my mechanic. The problem ended up being my battery and throttle body sensor.
