I overloaded my lathe using a slow speed and blew this board up. My fusing was incorrect amongst other things, I have now replaced both fuses Mains in and DC motor with circuit breakers .
I have since repaired the original PCB, by replacing the SCR’s and Diodes. Within the lathe I’ve upgraded all the wiring replaced all spade connections . I ordered a couple of spare PCB’s as insurance.
I’ve now gathered technical info regarding this unit eg. setting to work circuit diagrams etc. I you require my experience please contact me
