This want give you the correct reading.

The picture shows the stock bulk connector that is up by the drivers side head light. The bigger red wire goes to the bolt on the back of the alternator. The smaller red wire that was connected to the external regulator now goes to the #2 terminal.
The brown wire that was connected to the external Regulator now goes straight to the #1 on the alternator.
The white wire is terminated and not used.
You should run the small black ground wire over to the alternator also.
Okay, that makes it a little clearer. I cut the brown & red wires at the old regulator and plan to use those to connect to the plug on the alternator. Is that correct? The wires that were on the back of the old alternator were blue & black, if memory serves me correctly.
