Start with checking the wiring.
With the engine off, you should have battery voltage at the BAT stud and #2 terminal on the side of the alternator. With the engine off, ignition on, there should be some voltage or at least dimly burn a test light on the #1 terminal.
Start the engine, at full governed throttle, there should be around 14-15 volts at all three terminals, and across the battery. If there is good voltage at the alternator, but not across the battery, there is a connection problem between the alternator and the battery, possibly at the amp meter connection.
The RPM may be too low to initiate a charge. If all the wiring checks out, try a one time "cheat" on the governor, manually bring the RPM up above the governed speed just for a second to see if it starts charging. If it does the pulley can be changed out for the smallest pulley you can find. Pulleys can be bought at many sources, speed shops carry them. Be sure to get the correct width.
If all checks out, and still no charge, take the alternator to the auto supply and get it tested.
