Hello,

A fellow homebuilder friend of mine has a old-style three-LED (Red|Green|Red) MAC Trim Position Indicator. The Green LED was burned out, and the wires were cut off too short.

I told him I would try to replace the LED and lead wires. I got it apart without completely destroying it. But the internal wiring and polarity of the 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 wires? (Or did there used to be four wires?)

Does anyone have a PDF schematic of the 3-LED MAC Trim Indicator that you could email to me?

Or better yet, does anyone have a spare or unused one of these they would like to sell me?

Thank you,

Matt Dralle
