Hi, Does anyone have any experience with these items. I am trying to fix an old machine that uses one of these and I have no schematic diagram at all. I have traced the wires and drawn my own. Now having tested it I am suspecting that one of the legs is open circuit which means I will have to replace it with silicon diodes, as Selenium are very expensive. I have included drawings and a pdf file. The pdf file is how the rectifier is connected to the circuit. Basically one of the solenoid coils of the hydraulic valve started to draw a lot of current and I at first suspected the coil but then I needed to know if the rectifier was fine. I feel I am getting too much voltage on the coil. It is going up to 380 V and does not sound correct. On che.cking the rectifier I noticed what appears to be two legs open circuit but I may be wrong. Thanks in advance Ed
