Little back story. Bought a 1993 AJV 25-404N w/M32A control about 2months ago. Bought it knowing it had some problems (mill would run but sindle digital and feed digital display wouldn't display correctly plus a couple of the control buttons would stay lit all the time) but guy i bought it from said he would get comupter rack rebuilt from Mitsubishi. Before we sent the computer out he changed the batteries. Thinking we might get lucky. We didn't.
So sent computer out for mit's to trouble shoot.
Mit's report said "INSPECTED AND TESTED THE CONTROL CNC-11. MC161 IS CAUSING A 115 OVERTRAVEL +Y ALARM AT BURN IN. MC126 FAILED ROM TEST. MC446-1 FAILED BATTERY BACKUP TEST. C0609 #THE FDD WILL NOT LOAD SYSTEM DISK."
"ALL REPAIRS ARE COMPLETE; ALL PCB'S NOW PASSES ALL EXTENSIVE DIAGNOSTICS TESTING PROCEDURES. THE CONTROL CNC-11 HAS BURNED IN OK."
After reinstalling computer mill has all the same problems that mit's said it had. I Have a Battery Alarm, spindle and feed digital displays still don't display correctly, jog button always lit, and have a 115 overtravel +Y alarm.
Also to even get it to start. Have to power it on, hit zero key, power off then power on. if you don't do that it will not completly start.
I'm lost right now. Not sure what to look at next or do i just send computer back to mit's?
Also mechanicly i can fix most anything but electronics i have only dipped my toe in. But electronics doesnt scare me. Just never really needed to fix anything like this before.
