So, I have had a frustrating problem for the last couple of years. In summary, it's an 87 Monte Carlo SS, 383 stroker, with a 105 amp alternator. I'll get a brand new Optima battery, the car will start once or twice and the battery is dead/fried and has to be replaced under warranty. So the car keeps eating batteries and I have replaced the alternator three times now. I'm unsure how to troubleshoot this if anyone has some guides, flow charts, or ideas?
