Looks Like A Bad Alternator

[Bruzilla]

I just installed a new Autozone alternator on the Roadrunner, and it looks like it's bad. I'm showing a discharge on the dash meter and the battery voltage isn't increasing. Since I have headlight relays I know the alternator is connected to the battery, so it looks like another trip to Autozone.

If it is bad, good thing they'll replace it. It's lifetime warranty too isn't it?

In my experience, I would say you're right. If the voltage regulator was bad, I've only seen it overcharge.

The VR is new as well.

I went to pull the alternator to take it to get tested, and noticed the wire on the passenger side of it was off. Ooops.

I think that one is optional lol.

So was that the issue?

Yep. The alternator is charging like a champ now.
