Question about 1999 Jeep Cherokee
99 jeep cherokee sport 4.0l 6cyl voltage gauge will go to 19v. When vechicle was turned off it totally died. A few min. later it cranked fine but while driving it rose to 19v again. when left at shop it runs fine and shows 14v on gauge and battery and alternator checks fine.
The problem sounds intermittent, if you put volt meter on the battery while it is at that 19volt mark/reading(on the gauge cluster) you will be able to see if it is true. If your alternator is really charging over 16volts the lights should be getting brighter then usual and/or they are burning out. Find out ASAP, if the alternator has a defective voltage regulator, it needs to be replaced. Prolong use will damage components.
