ESC's getting HOT

Hi, can you help.
I am trying to configure the ESC on my quad but they get extremely hot every time I connect the battery (2s 2000). There are no beeps and cannot get the motors to turn.

Here is the set up I have;
CC3D FCB and PDB
Emax 12A ESC
2204 2300kv Brushless Motor
6030 propeller

Could it be a short circuit due to my soldering or is there another problem that I'm missing. When testing with a multi meter there is a constant connection between all positive and negative connections. Is this normal?

Thanks in advance for any help given.

I don't know if it's causing your problem, but a typical setup like this uses a 3S lipo, not 2S.

Hi RENOV8R, Thanks for your reply.
I have a 3s 2200 to use when I actually get to fly the thing but was using a 2s from a Syma X8G just to test and configure. Could this be the problem?

I think Emax mainly makes 2s-3S ESCs Might get an 8$ multimeter, and do a continuity test. What are you running off the BEC?

Hi GJH105775,
I tested with a multimeter and had a continuous connection across all the positive and negative at the PDB. Is this correct? Not sure what you mean by "What are you running off the BEC?" Could you explain as I am new to this.
When I said the ESC's get hot they are too hot to touch in under a minute.
Thanks for your help.

Unplug your motors, and see if you are getting a connection between ground and hot. Polatiry matters as many ESCs use a diode shorted across positive and negative (backwards)as polarity protection.
