Came back from an unexpected and unwanted covid vacation to one of my machines not wanting to cut. I have checked all of the fuses and relays. Relays are pulling in when they are supposed to. Voltage is good. Contact light comes on. But when it is time for it to start cutting, nothing. Just feeds in until it breaks the wire. The AE unit and PMU's seem to be functioning correctly from what i can tell.
