(John Baer) ________________________________ Message 1 _____________________________________ Time: 04:32:27 PM PST US From: Matt Dralle Subject: RV10-List: MAC 3 LED Trim Indicator... 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 Matt G Dralle | Matronics | 581 Jeannie Way | Livermore | CA | 94550 925-606-1001 V | 925-606-6281 F | dralle@matronics.com Email http://www.matronics.com/ WWW | Featuring Products For Aircraft ________________________________ Message 2 _____________________________________ Time: 04:36:32 PM PST US From: Matt Dralle Subject: RV10-List: MAC 3 LED Trim Indicator...

From: John Baer Hi Matt, The obvious (but probably incorrect) answer is that the chassis is the 4th wire. Is the housing metal?
