I blew a fuse that interrupts the Y axis servo. When I finally figured out what caused my Y axis to stop moving I see that there are three fuses in the upper left of the control cabinet. My question is What is the correct fuse? The one that blew was a MDL 5 Amp and the other two are ABC 20 amp. I'm guess the 2 20 Amp fuses are the correct ones but I want to be sure.
