BEC Melted Wires

[fastbaja5b]

Ok this has me puzzled.

Savage Flux with a Hobbywing 150A Esc Turnigy HV767 Servo and Spektrum RX, 4s Lipo set up. I hooked up the ESC to the receiver, with an extension lead with the red wire missing and then hooked up the BEC using one of these

between the Deans of the Lipo and ESC on one side. (ESC has dual Deans in a Series configuration like the Savage Flux Set Up does on the stock esc)

With the JST end plugged into the input wires of this BEC

And the output connected to the Battery socket on my Spektrum Receiver.

Plugged everything in, RX has power, Servo moves fine, as soon as I turn on the ESC however, the wires between the BEC and Receiver melted as did the Servo Extension with the red wire missing between the ESC and RX

So I removed the adapter, extension and BEC, hooked up the ESC directly (using internal BEC obviously) and everything was fine.


....so what gives?

Any clues as I'm puzzled on this one!
