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?
