Everything used to work fine, but suddenly the APM does not longer get powered by the ESCs on the output rail.
If I connect power to the input rail or USB the APM still works (but shuts down once I disconnect the USB cable). Any guesses at what component broke?
A possible workaround seems to be to connect the +/- from the output rail to the input rail?
Thanks!

Make sure JP1 is inserted. If it is, the only thing left is the diode (D1).
