What happen if you lead the red wire in - Ie power ESC from rc pack...

I wouldn't try that if it were me. With doing so, he'd be backfeeding voltage across the BEC circuit that has already failed and he measured to be 1.47V at the output. There's some sort of low impedance shunt in that circuit and applying an external Rx pack will apply 5V directly across that low impedance. I'd bet that there will be some smoke as a result.

I say let it smoke.

Well, I just had the same problem. After the first 5 min of running my bec went to 1.09 volts. I came in and tried a receiver pack and everything runs fine off of it. My setup is a 9xl on 6s in a 3905.

Wow, I'm surprised. I'm curious as to how much current the Rx pack is having to provide in this instance. Does the Castle Link work on yours without having to power the ESC with a Rx pack?

Nope, cl doesn't even see that it is connected to the computer. The weird thing is after I connected the receiver pack I disconnected it to put a Castle bec in its place and tried it again and it worked normally for a few minutes then flaked out again.

I'm willing to bet the power from your PC USB port isn't capable of providing enough current to run it. That's likely why you can't see it with CL. Powering it with an RX pack while connected to CL may solve that issue.
