Hi guys, new here. I've searched everywhere for answers to my problem with no luck. Found this forum so hopefully someone can help. I have a 2001 blazer lt 4wd 4.3l vortec. The alternator went bad few days ago. I drove it about 8 miles, from work to home then parts store. I bought new alternator. Installed it right there. Truck starts, alternator charge at around 14.4 or so volts. And the battery light flashes with no pattern. On a few seconds off a second, on 15 seconds off, etc,etc. had the alternator tested and the battery. Both are good. All fuses are good, and no loose wires. Battery doesn't discharge while driving. Sitting in truck for about 15 mins, turned on lights, radio. Without engine running. Started engine and voltmeter sits just below 14 volts until I rev engine a little. Meanwhile battery light still flashes. Anyone have any ideas what the problem is?
