Yesterday, when I was driving home, my check gauges light came on and dinged at me on my 99 Jeep Cherokee. The battery gauge was all the way over at the highest point. I drove home (about 2 miles max), turned the car off, and then turned it back on and everything was fine. Same thing this morning when I drove to work. Tonight after work, it wouldn’t start. It wasn’t really like the battery was dead, but like it wouldn’t quite fire. The radio was working. Any ideas? ---

That usually means the battery is being overcharged. And that can mean two things. Either the battery is completely shot, or the voltage regulator in the alternator is defective. Tester ---

The voltage regulator is controlled by the ECM. You could have a problem with the associated wiring or the ECM as well. ~Michael
