ramps shuts down when power is connected to 11A heatbed terminal (1 reply)

For the first time, I took my heated bed up to 110C and it held up fine.

A few hours later, I performed a pla print with heated bed at 55C and it came out fine

Then, the following day, when i tried to power on my printer it would not turn on, I disconnected the 12V power input just to the heated bed and and the printer turns on. But as soon as I reconnect the 12V to the 11Amps input on the ramps board, it will not turn on.

My guess is that something shorted out, but not sure where to start troubleshooting.


Thanks
