APM2: Rx bus not working?

I'm moving my APM2 from fixed wing to quad.  Downloaded and configured new firmware, everything seems good.  Planner can connect, artificial horizon works, etc.

Plugged in Rx, and had this problem:

- no power to the Rx, the Rx power light is off

Moved + wire to another rail

- power comes to the Rx -- power light is on

- can move servo attached to the Rx

- APM2 cannot read any values from the Rx

Questions:

1.  Any general advice on what the problem might be?

2. What's the best way to go about diagnosing problems such as this?

Many TIA! Video showing problem here:
