The "A" wire always goes to the battery.
The "F" wire always goes to the Alternator "F".
The "S" wire may go from the regulator to the alternator and it would go on the "S" screw. In this case the "I" wire from the Ignition switch would go to the "I" screw and this set up would be for a light on the dash system.
If you have a gauge then the "S" is not used or goes to a choke heater and the "I" wire goes to the "S" screw. The "I" screw is not used.
