I am going to buy the lifetime warranty alternator from Autozone seeing as it's across the street from my mechanic. He's charging me $160 to replace it which I think is very fair. Don't know what else it could be.
You have a seriously old battery. That happens with really old batteries. You'll read 12+v when you put a tester on it, but if you can have an assistant turn the key to start while you hold your voltage tester on the battery you'll see it drop to 6-8v, too low to start. That's one way to do a load test if the auto parts store guys don't know how to do it. Since your electrolyte is depleted- your battery doesn't hold "juice."If I take the lead off while it is running the engine dies. On Battery alone, I get no lights whatsover. I checked the terminal voltage. It is allowing 14.5 volts through and I did have the engine running.So what the Heck is going on?
