My motor cable was cut by the rack and pinion

I tan over the cable going to the y axis, it sparked and all the gecko drives quite working- no lights on them.
I shut off the cnc and unplugged the bad cable , still all the gecko drives are dead.
Could something be causing them not to get power or would all 5 drives be ruined
I just don't see how all of the drives would be ruined.Don;t know what else to look for the power supply comes on and there is lights on the pmdx breakout board the router turns on when I push the f5 keyso it seems like the bob and power supply are good.

Any suggestions?

the drives are gecko201x

Thanks
