Okay now the light flickers. And then it stays on when I am using the headlights or ac. It goes off when I rev the truck up. I will be going to get the alternator checked today
You might want to check the lone wire that plugs into the top of the alternator for a good connection.The heater hose that crosses over can play havoc with this connector.I think I would do this before condemning an alternator.
