Jeep cherokee 2001 Problems volts rise too 19 while driving!!!
Iv had this problem for a month now and my jeep stopped running and all and thought it was the alternator so i replaced the alternator because it was cracked in 3 spots and the guy said it was bad. Once the new one was in I then started it and for the day it was running as if nothing was wrong but then it stopped working again. Found that a fuse in the fuse box was loose. I tighten it and it ran but the check gauges light comes on if im driving past 40 mph for too long and the volts go from 14 too 19 while the gauges light is on. But once i stop at a red light it shuts off and volts go back too 14. This cant be a problem with the alternator since i replaced it and its still happening and i checked the battery at advanced auto and they said it was good twice. What could be the cause of the check gauges light coming on and bringing the volts all the way up too 19?? As of now im not sure what can be causing this problem since i thought it would be the alternator causing it. It only happens when im driving fast for awhile but if i continue to drive it can come on and shut off but if i stop at a red light it always seems to shut off. I tried finding what can cause it and found that maybe the temp sensor thats in my battery tray may be going bad but how would that cause this problem?
