In my K5, I was driving home and suddenly my alternator belt started squealing and my volt gauge (aftermarket Autometer) pegged out past 18 volts. I was stuck in a line of traffic for about 15 minutes with it running like this. When I checked under the hood, my Optima red top had been squirting fluid out of the breather holes. I cut the alt belt off and drove home just on the battery. Did I do any damage to the battery where I need to replace it for safety or reliability reasons? It's a 140 amp Powermaster alt if that makes any difference.
