BROWN wire to positive of 12 volt battery.
BLACK wire to negative.
BLUE wire to multimeter positive.
1. Check the rotor turns freely.
2. Each vane in the rotor has a magnet in it
with the pole facing out.
Check that the 4 magnets are present.
3. Check every second magnet has the
same pole orientation so the rotor
magnets are N - S - N - S.
4. Connect negative from multimeter to
negative of battery.
5. Set multimeter to DC volt.
6. By turning the mill wheel slowly, this will register approx. 8.0 +/- 1 volt
with the diode on and 0.3 +/- 0.1 volt with the diode off with every second
magnet.

BROWN wire to positive of 12 volt battery.
BLACK wire to negative.
BLUE wire to multimeter.
1. Connect negative from multimeter to negative of battery.
2. Set multimeter to DC volt.
3. Bring a metallic object (distance 3 to 5 mm) up to the transducer. This
will register 1.4 +/- 0.2 volt and the diode will turn on.
4. By removing the object, this will register 12.0 +/- 1.0 volt. Diode is OFF.
