    do all your output tests with battery connected.this will trigger the voltage regulator to do it's thing since it sees a load .
    you will see the unrectified ac output voltage on the green wires drop once battery load is connected.

    you can put a dc amp meter in line on the regulator output and calculate your wattage ouput.
    Amps x volts = watts

    The AC output test was done with the battery connected. The green wires were disconnected according to the manual.

    this was an error in manual.
    it says in revised book to do it green to black whilst in circuit and engine around 6k rpm.
