How to test a Menzimer(MAC) elevator trim position indicator

Looking for information on testing the Menzimer(MAC) elevator trim position. Applying 12v power to it will not produce any lights. I applied 12v power to my known good flap indicator and did not get lights either. Would consider the purchase of a good used Trim indicator w/LED lights for testing. Mine has a 6 wire plug.

You need to connect the trim wires per the Ray Allen diagram to the trim position indicator and then grab a 9 volt battery or equivalent and run the trim motor up and down, should see the lights come on and indicate movement of the trim.

MAC is now Ray Allen, look them up and download the schematic for wiring the indicator to the trim motor.
