So last night I am driving up a hill and once I got to the top the electrical system went crazy. It was night and I saw the stero flash a couple times and the engine died. I was going less then 20mph. At that point I put it in park and restarted the engine without any problems. I had to reset the clock and now I am getting a change oil alarm even though it has only been about a month since my last change. The only thing I have to compare this with is when an alternator went bad years ago but that car had 120K+ miles, my Jeep is just over 18K. I plan to take in to the dealer early next but but I would like to hear thoughts.

 

Make sure your battery terminals are tight/clean. Any battery light come on? Low voltage or loose contacts can cause haywire on electronics.

 

Every single light I have came on but I will check to make sure the contacts are clean, was in the desert last weekend.

 

hey dave i had a issue a 6 weeks ago. the WCM had a issue with the key fob. I think there is a TSB on this have them look at that. supposidly the TSB changes the WCM.

 

Search "stall bug" and do some readin. Sounds like you might have it.

 

yea, I agree.
I doubt it's a bad alternator. If you have a volt or multi meter, check the battery statically. The battery should read about 12.65VDC. Then start the engine and read the battery, it should be reading about 14.5VDC. If it's not reading that voltage with the engine running there may be a problem.
I've heard of no problems with the alternators in the Jk as of yet.

 

as per Lorrel X2

 

x3. If no constant alternator light, no problem.
