Mushroomed gave some good suggestions to bypass the BEC, another option is to draw power from the #2 cell on your balance port to get unfiltered 8.4V with a fresh charge:
How to wire HV Servo from 2S LiPo
You can use this bypass to the Ch2 port on the Rx, I am showing a 2S-JST plug in the pic, but the same can be done with a 4S-JST, use a voltmeter to double check the voltage is 8.4V beforehand, assuming your Rx is rated for HV @ 8.4V:
If your Rx can only handle 6V, then I would get a UBEC like this instead:

I think this is the route that I need to go, but you are speaking so far above my head that I can't keep up.
I spoke with Castle Creations and they suggested doing exactly what you said (testing brown (-) and red (+) Rx lead wires). Interestingly, I didn't pick up any voltage. Probably why ESC isn't powering my RX.
So, I think we can safely assume that the BEC is fried. Can you please help me understand how to bypass the BEC/add external BEC in layman's terms?
Would be awesome if I can send vids of what exactly is happening? Much appreciated!
