Tom: Your new alternator will have built in regulator, plus necessary diodes, etc to make it work properly. If the gauge checks out then you must have a broken wire somewhere. I'm looking at the wiring diagram for serial number 57724 and above. According to that there in nothing at the dash as it applies to charge, start and ign, except key start switch, charge indicator and neutral starting switch.
If those are all good, alternator is new, then it has to be a wire between dash and alternator. I see what is called a resistance unit, (No.19 in the diagram) just behind the alternator, doesn't appear to attach to alternator, but it does have 3 wires to it from harness. Bear in mind the ignition wire to coil runs in that harness, and it may be a resistor to coil.
To bad John T or one of the other electrical gurus would jump in here. That resistor may have something to do with charging. If it were a resistor reducing voltage to the coil, it should only require 2 wires.
