Hi, need some advise. Every now and then my check guages light comes on when I first start it up. I notice my amp guage reads zero. It runs that way for a while and then it registers to its normal position. Is that a problem with the altinator or is there a sensor for the amp gauge. Ive looked at it couldnt see a sensor. I'm going to check the output on the altinator. See if it's OK. and charging when the amp guage registers zero. Anybody run into this. Thanks for any advise. By the way it's a 2000 Cherokee sport 4.0 automatic. Robt.
