S terminal unplugged you're likely just reading battery voltage and not charging at all.

The battery terminal at the alt will read battery voltage with the truck running or not running.

Joe, 12 volts will not charge the battery.

Electricity(Current) flows from a higher voltage to a lower voltage. The battery is right around 12V. So, in order to charge the battery, the voltage in the battery cables has to be > 12V, usually 13V-14V.

So leaving the S unplugged will not solve your problem.

Unplugging the S, if i'm not mistaken, disables the alternator.

Try a new voltage regulator.
