I have a LakeShore Model 336 at one of my customer locations. All of the sudden we had the 4A Fuse Blow, changed out to a new one and blew again. After doing some troubleshooting I found after unplugging all
Connections from the transformer, the fuse would not blow, so u started plugging in each connector one at a time to see what path was causing the fuse to blow. Once the connection at J7 on the power board was plugged in the fuse would blow. I checked the some of the in-line caps and seem all to be in good order, no visual signs of any SMT components burnt or broken. Has this issue been seen before and what may be the possible cause for this to be occurring?
