Well, it wasn't the alt that died, it was the harmonic pulley. But the battery discharge warnings and trip resets continued. So I replaced the battery.

With the old (newish) battery, in just 15 Minutes if having the door open and ignition on, with the engine off, it would throw a battery error up.

The battery that was in it was only 70Ah. My new one is 105Ah. I hope that's the end of the issues. Once I get the computer coded to know it's a 105Ah anyway.

I registered the battery. But there's another step when changing sizes.
