I have a Monarch EE1000 that has been updated with a Southcom solid state control. While using it today after about 15 minutes it just stopped. Upon checking, found that it had both tripped the circuit breaker and blew a fuse in the machine disconnect box. Finding the blown fuse about used up my knowledge of the electronics, so called in a industrial electrician friend to examine it. He found out that it appears that one or more of these SCR diodes has shorted.
My question is this. Is there a way to test these diodes? There are six total, and they do the "heavy lifting" converting the 3 phase input into DC that powers the spindle motor so are an important part of the machine. We have narrowed it down to 2 potential diodes, but do not know how to check them, or worst comes to worst where to buy replacements.
