Battery/Alternator?

Got into my 2001 WJ 4.7 to take my boys to a movie. Heard a constant dinging and saw a light lit up that read "Check Gauges". The only gauge I saw that looked off was my Battery Gauge, it looked low. Saw the movie got in the jeep, it started but on the way home the needle just kept dropping. Got home pulled it in the garage, shut it down and tried to restart 3 minutes later...dead. Sounds like the alternater to me. any other thoughts? Charging the battery now, hopefully enough to get me the 16 miles to work at 5 tomorrow morning. I can work on the altenator there if needed. Do I need a Mopar one or will a napa/autozone one be good enough?

Sound like possibly the alt. As long as the battery wasn't drained right down it should be ok. I've never had any issues with anything I've bought at napa, and prices have always been pretty good for around here anyways.

Most likely the alternator. I would pull it and go get it tested along with the battery. If the alternator needs to be replaced, any brand will work. I got a rebuilt one for like 90 bucks after the core return. I had to replace mine because of a bad bearing.

Is it broken?

That is what it was. Was able to charge the battery enough to get me to the office. Disconnected the negative side of battery, Jeep died. Replaced the Alt in a few minutes, good as new!

I wish I had seen this earlier....you would have been better off to get the Durango alternator for it. Costs less and puts out 160amps as opposed to the 132amps. Direct fit. Search my posts for details.

The Autozone unit is fine though... damn...could have helped a brother out. Oh well, good diagnosis from the folks here & glad you got it sorted.

Next time it goes out...and I'm sure there will be a next time. I'll take you suggestion and go with the Durango Alt. Appreciate the information.
