99 Wrangler, 4.0 auto. I haven't had a chance to really get into this yet so I'm gonna get some opinions before I tackle my problem. On the way home tonight (only about a 3 mile drive) my check gauge light came on and my voltage gauge was spiked, parked it and shut it off. Came out a few hours later and started it up again and it was fine. I haven't checked it with a meter yet, I'm gonna do it in the morning. Anybody else run into this?
