Bed Heater fail

Hello, have following problem on my MK2S, bed stopped to heat, checked everything, connectors, heater resistance (1 ohm), etc. Found that without the heater connected the output is 12 VDC and the red LED on the board turns on, but when I connect the heater falls to 0 VDC and the red LED on the board turns off.

Thanks for any help

Sounds like there is a dead short in the wire going to the bed from the 12v source.
