Question about 2006 Chevrolet Tahoe
Randomly my battery light will flicker on and off with all the gauge needles bouncing to zero then back and a clicking noise in the dash as it does this. The alternator or pumping out around 14 on a multimeter, what could be causing this?
They may very well be bad. It is a common problem that affects thousands of GM/Chevrolet owners. Check grounds first, multi meter will show positive if bad I would think. GM may at their own discretion replace them for you if enough pressure is applied to the dealer. Lastly, stepper motors can be found on many sites including eBay and you will save a ton of money if you DIY. Sorry, my 2003 Tahoe has been fine so far although less than 20,000 kms on the gauge. Just used to tow boat and race car to local track. Good luck and if I find anything else, I will post!

SOURCE: fuel sensor gauge
you will need to replace the fuel level sensor.(sending unit) it is in the tank and is hooked to the fuel pump. you can buy seperatly from pump. you may finf it easier to remove the bed if you have some help. it is six or eight bolts and harness unplugs then you can get right to it.

Sounds like the oil pressure sensor. Thatt is the easiest thing to change. If not its the gauge. Put voltage to the wires from the switch and see if the gauge stops jumping and stays pegged, if it does its the switch Good luck
