Anyone Know What this Connector is Called?

I'm hesitant to put all the blame on your crimping or reattachment of the red wire to ammeter.
If that was the case, then the terminal through the bulkhead shouldn't have failed.
Other than charging, normally there's not a lot of current in that line. But if there are other problems, then that changes. That's why I asked if you noticed what the ammeter was showing before and/or during this meltdown.

For the repairs.

You say the terminal through the bulkhead failed, what exactly do you mean by that? If you're referring to me trying to replace it due to being misshapen or warped that was from me trying to remove it because the slot is such a tight fit. Or are you referring to it frying the red wire on both ends of the firewall? I was under the impression it's simply a connection to keep current flowing and that shouldn't stop it from frying on both sides.

Just trying to understand what you mean by it failing and don't want to give a false impression.
