Subject: Zenith-List: MAC 3 LED Trim Indicator...
Hello,
A fellow homebuilder friend of mine has a old-style three-LED (Red|Green|Re
d) MAC Trim Position Indicator. The Green LED was burned out, and the wire
s were cut off too short.
I told him I would try to replace the LED and lead wires. I got it apart w
ithout completely destroying it. But the internal wiring and polarity of t
he LEDs isn't that clear to me, nor is the actuation of it through a servo
electronically. I'm not sure how to activate three LEDs with only three wir
es? (Or did there used to be four wires?)
Does anyone have a PDF schematic of the 3-LED MAC Trim Indicator that you c
ould email to me?
Or better yet, does anyone have a spare or unused one of these they would l
ike to sell me?
Thank you,
Matt Dralle
