    I burned out the 5V regulator on the power distribution board. Replaced it, but I see 3 wires going to connector 9 of the FCS. I can figure out 5V and GND, but what is the third wire?

    The Telemetry displays main battery voltage so I would think its the main V sensor wire. But I could be wrong. Did you take pictures before you pulled things apart?

    Hopefully one of these pics may help.

    Thanks, I have dug around and found a schematic basically showing what you say. There is a voltage divider between battery power and ground, with the white wire picking off the divided voltage. I appreciate the pictures as they show me some other things that I am wondering about. FR36JWOI1MQ5UVW.LARGE.jpg
