I have a BP S1 RR with a Hill Billly BOB running Mach. The machine has been running well for a year. Recently, I have been having troubles with my x axis and now it stopped working. I have gone through all of the diodes and transistors several times. I noticed now that I have no voltage at wire 24 (this is the wire that feeds the infamous FU12 fuse) I tried to trace this wire but I can't. I have the schematic, but it is photocopied and I can't make out anything. Can anyone help me out please? If I could get a good resolution schematic that shows me where this wire comes from, it would be great. otherwise, if someone could just tell me, that would be fine too.
Thanks Much!

I have no idea what is kept with this conversion. But fuse 12 is the DC side of the bridge rectifier. I believe fuse 15 is the AC side of the bridge. The bridge is fed by T2.

George,
Thanks for the reply. I must have a broken wire somewhere. My power cabinet checks out OK (including FU 15).

I had one very unusual case where a BOSS 5 had a lack of power From T2 to the bridge rectifier.. This is a number 14 wire that does not move, yet it went open. Go figure. It was a illogical problem and took a little while longer to find.

George,
Thanks, that sounds exactly like my problem. Is there any easy way to get a t those bridge rectifiers? They are buried near the transformer, right?
