New to me Bridgeport Mill with issues

So I wired up my new used Mill this weekend and the dro worked but the power feed would not work. Tonight I inspected the power feed and found a wire inside disconnected and the fuse blown. Connected the two black wires back together put in a fuse turn it on and the three phase converter went Haywire and the dro shut off. On the circuit board of the power feed a resistor smoked. I've then rewired the ground on the Main Power thinking that might have been an issue and still no dro but when I power the power feed back up it then popped the fuse. Still dro won't turn on and I can't find a fuse or reset button. Looking for any and all suggestions. I will upload some pictures as soon as I figure out how.
