Hey guys,
So, I'm troubleshooting this linear power supply (12Vdc) by doing the basics first. Tested primary side of transformer, tested fine (120Vac). Tested secondary output, seems fine (33.6 Vac). This is then connected directly to a what I'm pretty sure is a bridge rectifier (part no. 70CT01P, couldn't find a datasheet). Tested the DC output of the rectifier and get 0V
Unplugged all connections to the rectifier and used the diode test function of my meter. I'm getting a forward voltage drop across each diode and no voltage drop in reverse bias across each. Using these conditions I then drew out a schematic according to my tests and I'm getting confused as to how this particular rectifier is connected.
I attached a schematic I drew out according to my diode tests which doesn't seem right. Also, the labeling on the rectifier doesn't specify positive or negative for the DC output, it only has 2 positives. One can be seen on the top of the picture I took. The bottom side looks the same except the sine wave symbol says AC.
Thanks,
Dave
