Hi, I have a HEIDENHAIN VRZ 731B fitted on a Bridgeport Milling M/c. Was all ok but now just blows the 400mA fuse on the back. No lights, nothing. Any ideas? Anyone have a circuit diagram for this?

Get Heidenhains number off the web and give them a ring.
I have found them to be most helpful in past circumstances unlike Fanuc who even want a credit card number to talk to you.
I did try them. They say the support stopped 15 yrs ago. Plus no circuit diagrams available. I'm guessing it's a Power Supply issue.
