Installing one wire alternator

I believe it is a one wire to the battery, but I didn’t realize there was an addition wire to a ground, but does anyone know what you are supposed to do with the old wiring to the alternator and voltage regulator. I remember seeing something about unplugging them awhile ago, but I closed the tab
You need to describe exactly what alternator you have. Whatever you know about it - Is it a Chrysler? Who you bought it from? Or a photo?
As you can see from the discussion, none of us on this side of the screen really know what you have, why you bought it and what has been done to the car.

An alternator works by spinning an electromagnet. The spinning magnetic field induces electrons to move in the surrounding static windings.
That electromagnetic needs power to operate, and something to control that power. That something is the regulator.

The illustration shows the spinning electromagnet and a regulator controlling the feed. (The second brush is grounded to the alternator housing.)

(1970s regulators (the ones with the triangular plug in connector) are connected to the second brush with a wire.)

The idea behind the original alternator wiring is this: Power generated by the alternator goes to run the car, then any left over is available to recharge the battery.
