Where does this wire need to go?

Here's the pic we've been waiting for.
And per his email:
"Ok, this is the regulator, you can see how we have tied in to the alternator with the wires that I am holding on my finger there.. This does not seem right at all so I need to know if we did it right or if we should just rewire everything."

He also stated a couple of the wires were getting hot enough to melt.

Now we can solve the mystery!

Get rid of that yellow wire between the tape and the butt splice and ground the regulator. That wire is going to cause the alternator to put out full amps at all times (will overcharge battery) and be a drain when the engine is off.

Ok, so the regulator does need to stay? Someone told me that the new alternators have a regulator built in so the other one is not needed.

Depends entirely on what "new" means in your case maxcruise.
Just getting a new or rebuilt alternator of the same model type as your old one would require that you retain the external voltage regulator.
If you are upgrading however, to a "newer, or more modern style" of alternator, then yes, the answer is "most likely" you won't need the regulator any longer.

So we have to know exactly what you're getting. If you buy a simple replacement for your Bronco from an auto parts store, you need to keep the VR wire in.

Where exactly is the A ( yellow ) going to. When we removed it from the splice, the alternator would not push and it was running off of the battery.

Battery side of the starter solenoid.
