I connected up my Bridgeport mill which I just acquired. The 3 phase socket which connects the head motor to the control box needed replacing which I've done, along with the plug to the motor. First try, everything worked; on button, stop button, and everything else apart from the X feed, which I knew didn't work. I switched to the 2nd speed setting on the head and it stopped. I removed the motor and tested it directly from 3 phase socket, no issues, both speeds forward and reverse work. I then found one of the phases into the control box was brittle and had snapped, wire replaced, still no joy. After much fiddling about, I figured the relay to the motor was dead, as the motor would run when you press the relay in manually but wouldn't respond to the on button. I swapped the 3rd relay, with the fourth which seemed to be from the X feed and therefore redundant, in the swap over, my brain, which I thought was capable of retaining the necessary data, failed, and although the swapover still seemed logical and obvious, I'm now not sure. Now, with any of the 3 top relays pressed in manually, everything works and you can switch on and off the spindle motor, suds motor etc as long as one switch remains in the on position. The off button works, but you cannot turn the machine back on with the on button, you have to press in one of the relays. The 110v feed from the transformer is fine, I've checked with multi-meter. The PCB shows a fried R6 resistor, but I am assuming that this only affects the X axis power feed. All the relays seem to work and hold, can someone please indicate to me how the feed to first energize the start relay is wired up so I can work out what, if anything I've got wrong. I've searched for wiring diagrams but all I can find is hand written ambiguous diagrams or photos only showing the top row of wires, which are the load wires. Thanks
