1.20.10 night shift

#23- finished putting screw back together. Set a mold in and made sure nozzle was aligned correctly. The machine had not used cores before so I put quick connects on. Also wired the core switches up on the mold and put QD fittings on it as well. When I tried it out, cores would not work. I remembered Collin saying that he had found a problem on the circuit board inside the valve on 22, so I swapped out boards to eliminate that. Still did not work. I swapped out hydraulic hoses. Still not working.

I was at the point of replacing the quick connect fittings I put on the machine but there are none left in MRO. You can manually probe the valves while someone energizes switch and the cores will move, they just do not seem like they are getting an output signal. I tried to bypass the switches and run it on timers but it still will not work.

I went through it all with Mark and Ronnie, we got to a point where we had isolated a problem with the valve.
