I’m finally getting some time to fix fix some random stuff on my suburban. It’s a 1999 k1500, 5.7 liter, 4WD with just under 250,000 miles. It runs flawlessly. No aftermarket electronics. For three of four years the volt gauge on the dash has always read very low. I’ve checked battery voltage countless times. It’s never been below 12v. Question. Does the stock volt meter get a reading from a specific area? Cables are good and solid with no corrosion. Grounds too. The picture shown is actually a decent reading it’s usually in the red. Is it just the motor for the needle in the cluster?
