What wires run on alternator?
The three wire types in a three-wire alternator include the battery positive wire, the voltage sensing wire, and the ignition input wire. The battery positive wire connects to the starter. The voltage sensing wire connects to the battery, and the ignition wire connects from the alternator to the key switch.
Where does the alternator power wire go?
Locate the terminal on the alternator labeled “B”, “Bat” or “Pos.” All alternators have this terminal. The wire that connects to it is red and goes to the battery. It is a heavy duty wire as it has to carry high current.
What does R and F mean on a alternator?
The R and F terminals are the ‘Reference’ or voltage sense terminal and the ‘Field’ terminal. The color on the spade connectors doesn’t matter, you will have to use a multimeter to determine which connector goes to which pin. The R will be hot at all times while the F will only be hot when the ignition is keyed on.

Is the same model suburban with the correct battery?
(If you have a same-model Suburban with the factory/correct setup, you could send a picture as an answer, rather than trying to decode my setup and see if I am fixing it right.) The vehicle was fine until installation of a dual-battery setup. This was problematic, and since has been removed.
How do you run a 1 wire alternator?
1-Wire alternators require only 1-wire to operate. Simply run one wire from the alternator ‘battery’ terminal to the positive terminal of the battery or to the starter solenoid main lug, which is connected to the positive battery post. Make sure that the battery is fully charged. Reconnect the ground
What is the Grey wire coming out of the alternator plug?
As for the grey wire coming out of the plug-in for the alternator. I have no idea, GM only used one of the wires on gas engines, the second wire is for the tachometer on diesel engines. Maybe at some point someone replaced the alternator plug. I would do as you suggested and not connect it to anything.
