I have a Diversa-Tech VMC the company was based in Indianapolis IN. I have no electrical print and can't find one. When I turn my machine on it comes up that I have overtraval in both directions for all three axis. I have checked for a grounded wire, I don't think I have any gounds, but I can't find 24 volts any where on the machine. I have no real over traval, , all the switches are closed. I changed the I/O board-that was a mistake. But originaly it did have a blown fuse, changed it and it did not reblow, but still don't work. I have no lights on this board. I can't find any 24 volt power supply on this machine, I assume it uses 24 volt control voltage. I also can't find 24 volts any place on the machine. I did find 12 volts. Any help would be welcome.
Thanks
