Hello, i have a mori seki mv jr with low voltage on the 24nc cicuit. Someone was diagnosing a low oil alarm when they shorted the nc24 to gound. After this it's 0,4 volts instead of 24v. I have allready stared to diagnose, but i'm missing electrical diagrams for the machine. Does someone know where the nc24 gets it power from, and if theres a fuse anywhere that might have blown. after this happened most buttons on the user interface are also unresponsive, but this is expeced since all voltage is gone. The machine turn on so i can see errors and go through menus. Also the p24 circuit has 24v.



The machine is a mori seiki mv jr 1985 with dc servos, and fanuc 10m



Thanks for the help!
