Possible Alternator Problem

I have a 99 TJ with 4.0L. It seems I've always had an issue with corrosion on the battery cables and terminals sometimes to the point where I'd have to go under the hood and move the cable on the post and everything would come back on. Well a couple of months ago I did a good cleaning with baking soda and all has been well up until today. Today when I get in the jeep it is dead. I try again and it turns over and starts. The radio is flashing so I know it lost connection totally. Well on the way to work, I seem to smell something burning but can't tell if it is coming from the Jeep or elsewhere and twice the voltage gauge goes up all the way and the the check gauges light comes on. Well I make it to work and after I park and turn it off I try to start it and once again it is dead.

I'm leaving early today and am going to check the connections to make sure they are not corroded. I've never seen the volt gauge spike like that though. I was also going to take it to Autozone and have them check out the alternator. Does anyone else have any ideas on what I should be looking for?

Thanks, Joe

you might have killed your battery...

get those $1 felt pads that go on the terminals....they work.


when @ Autozone they will be able to tell you if the alt. is good, if the battery is good, etc.

The TJ's alternator rarely fails. My $$$ is on you have a bad/weak/dirty/corroded connection somewhere in the battery wiring.

The voltage gauge spiking is also a symptom of a low battery or bad connection.
