istrument gauges bouncing
Have an 06 Z71, at random times the battery light comes on and as this happens all the gauge needles bounce to zero and back and there's a clicking noise in the dash as it does this. It does it sometimes on start-up or driving down the road (it's random and just started this past week). The alternator is reading 14.2 with a multimeter. I know the stepper motors go bad in these vehicles but the battery light coming on seems to be something else, any ideas what to look towards?
Check battery connections if they dirty or loose this can happen.
Check the alternator under load eg.ac running all lights on I've heard those years have cluster problems or shorts going on inside the cluster
