If he's got the wire from the Bat. terminal on the regulator hooked to the wrong side of the ammeter, (connected on top of the wire from the starter terminal), it will charge OK, and the ammeter will never show a deflection. The Bat. wire from the regulator should attach to the same ammeter terminal as the wires from the ignition switch. There should be only one wire on the side of the ammeter where the voltage comes from the starter to the meter.
