No Voltage Regulator

Working on a 1966 F100 and have very little past history on the unit. It's my first and quite the challenge.

Been trying to get it to start, and have had luck getting it to turn but not to fire yet.

Finally broke down and got a wiring diagram from classic car wiring and the diagram shows a voltage regulator on it. Had me scratching my head as I've seen no voltage regulator under the hood. Was wondering if and slicks came without a voltage regulator. Also the diagram doesn't show the red/blue wire to the S post on the relay. In fact only shows three posts in the relay.

Your help is greatly appreciated.

Could be the alternator was upgraded to gen 3 and the voltage regular is integrated into the alternator.

Pull your air filter off and post a few pix under the hood. These things are simple but it helps to see where you are starting from.

Look on the driver side under the hood on the radiator support behind where the running light sits.
