Hen I went wheeling last night my jeep started acting up. It was idling very low and sounded like it was missing and the battery gauge was kind of low. I kept it revved high and on the 40 min highway trip back it was fine and I le it idle for a minute and it's not low anymore. I think it's the altinator

 

You said its not idling low anymore, is it or is it not doing it anymore?

 

Take it to a parts store and have it scanned. They can test the alt and let you know if its bad.

 

It's idling normal now like it never happened and I am about to get it scanned at advance but our scanner sucks

 

Probably just got wet, happened all the time with mine, once it dried it was fine.

 

Sounds like the bearing is going bad in the alt. Probably won't be long before it starts making noise. Start shopping now.

The parts store could test it as good, but if the bearing is going shot, it may not show it as bad.


Sorry, I seen this post and said wtf I don't remember posting here

 

I got it tested and it said ripple?

 

Means the diodes are bad, time for an alternator.

 

Thanks for the help guys I'll order a new one from advance tomorrow
