Default Alternator question

Hi

I have a stock 75 with AC & auto trans.
I put in a new alternator, stock one.

The plug connection red wire broke off the other day & I drove it
for awhile and the car ran good.
Since then I replaced the plug and reconnected the wires.

Silly question:

What does these plug wires do exactly?
The reason I'am asking is the car did run with the red one off

Thanx

A

the red wire provides power to the exciter and the white wire provides voltage the exciter needs to see to turn on and provide power the car needs.
