VOLTAGE TESTING
The wire color is called out on the board but the lettering
is on the relay side of the board. You need to remove
the board to see the lettering, but you can follow the
wire to the connector without removing the board. Do
your voltage test by following the color wire to the
connection point then make your test.
The power to the control board from the power board is
coming in on the Green and Black wire. Green is neutral
and Black is power. To do the rest of the test you will
use the black wire. Your readings will be 5 VDC
± 2
until you make a selection. At the time you press the
Bend a piece of wire around hook on face and push
into center hook slot to hold front face while testing
voltage.

actuator, your voltage will drop to less than 1 VDC on
the wires listed to test the component, but the voltage
will remain around 5 VDC on the remaining wires. (See
Figure 38)
