Have replaced the main board and the Phantom FC unit .. Have power to escs but no power to FC unit .. just beeping ESCS from no signal.

Would like to know or have a schematic of the main board .. think the battery plug or connector is bad thus sending no power to GPS, Phantom 2 FC Unit and other components.

Thanks in advance

Think the 2 wire plug coming from smart battery isn't getting power into that portion of the main board .. tried outside power source for FC unit and its working

Respectfully
J.D. Wright

Any assistance would be greatly appreciated.
