First Self-Test Failing at Bed Check

Hi all,

I just finished with my first build for a Prusa i3 MK3S and am having issues getting past the self-test. The whole test goes smoothly until I reach the bed check. Within 1-2 seconds the machine shuts off and restarts after getting to the "Checking Bed" screen. Below I've included the screens of each check, in progression. Does anyone know why this may be happening? I checked the wires and everything seems to be intact and plugged into all the right places. Thanks in advance for any help!

RE: First Self-Test Failing at Bed Check

You have a short in the bed heater circuit. You've crossed wires, connected the bed heater wires to the wrong spot, or got the spade lugs touching something they shouldn't. Keep the printer off until you get it fixed or you risk blowing up the Einsy board.
