Hi , looking for some help guys , just got an old 1990 BMC 25 set it all up and it has issues , it boots up fine (max32 control)but needs the axsis calabrating as soon as you try and do this it errors , if i try moving any axis manualy it errors on that axis , seems theres no power to any drives so futher investigation found that its taking a phase down on the transformer to spindle drive board , if i disconect the 3 small wires from the input of the spindle board isolator switch to the board ( yellow wires labled r,s,t ) it has all three phases no problem ?, also I have just found fuses f4 and f5 are blown on spindle board , there seems to be no life on this board ( no lights at all) do you think the spindle drive is the problem or could anything else cause this , appreciate any help as i feel this could be a long job
