Need help please, with my Seig CNC. This is an early conversion from Arc. Had problems for some time with the front guard micro switch. So took out the switch and coupled the wires together. Solved the problem and all was well until I accidentally dropped the wires and shorted the main fuse. I can now hear the relay clicking in and out as normal but no spindle movement. If you have any inclination towards a possible solution, I would be extremely grateful.
