Well I have finally started tearing down the singer-link ga simulator I bought. I figure its been out in the weather for at least 20 years. The body is junk, all the plastic is brittle. However, the frame, panel, controls, insturmentation are all ok. They are all Aviation grade made with aluminum, glass lens, and so on. So far I have tested the airspeed,rpm,and turn ball gauges. They seem to work on a very low voltage. I tested them at 1.5v dc and they all went full scale. I figure they run on 0-1 volt normaly. If anyone know for sure I would love to know. I don't have any pics yet, my camera broke! It looks like the gauges are the real deal, genuine aviation stuff interfaced with the sim. Problem is, the compass, VOR, & artificial horizon have multiple terminals. Does anyone know how or where I can find pin out or wiring info? Since they all seem to work, I would hate to tear them down to just use the face when the drive motors and all are already there. Any help or suggestions would be great. I will certainly post pictures as I get them. I promise, there will be a lot of them.
