I wired a Micro-Trak into the wing tip and have not been able to get it work when installed in the plane. I pulled it, hooked up a 9V transitor battery to it and it worked just fine. Flew 2 flights and it worked just fine with a battery hooked to it.
Thinking it was the connector, I replaced it and hooked it up again. No GPS light. Hooked up the battery and GPS light comes on. This makes no sense.
Sooooo, out comes the volt/ohm meter. Checked the battery terminals via the connector and it had 8.7 volts and verified the polarity. Now I checked the wiring on the plane. Plane off and at the switch in the cockpit, showed 12.2 volts. Connector was 10.8 volts at the wing tip. Polarity of the plug was the same as the battery. It's designed to work on 9-15 volts so this should not be a problem.
What gives????
