When I opened up the failed power supply, I found that the input side of the high voltage transformer had shorted out to a near by capacitor. I opened the new power supply and found that the line followed the same path. I insulated the capacitor and line with kapton tape. I then added some non conductive foam between the problem areas. A quick inspection of the failed power supply also showed that the output line was rubbing on the power supply case. I made sure this was also isolated on the new power supply.
Don Kleinschnitz Jr. The power supply failure was not related to the oil from the refrigeration compressor in the cooling water.
Everything is working good as new. (as it should!)
First time I have seen this kind of failure. Is the old supply working now?
ReplyDeleteDon Kleinschnitz Jr. I have not done any repairs on the damaged PS. The replacement was modified with additional insulation and inspection of all areas that could possibly rub and cause a similar failure.
