I got this board from someone that got it from someone else. They want me to see if I can fix it. I think I know what the problem is, but I figured I would see what everyone here thinks. They said that it blows the main fuse(F1) every time it is plugged in. The fuse is in the black fuse holder below the transformer in the picture. Someone else originally worked on this board because the transformer broke off. They reconnected it by using all the wires jumped off of it, and epoxied the transformer to the board.
I checked everything on the secondary side, although I was fairly sure that wasn't the problem because the secondary fuses (F2 + F3) were alright. There were no shorts on the 2 separate secondary rails. I checked for shorts on the secondary side of the transformer, which has 2 outputs of 12v and 24v. One of them read around 160
, while the other read open circuit where I would have expected either half or double the resistance depending on which winding is which. I then checked the primary side, which read 0.3
between any 2 taps on the transformer. So, I am assuming that the transformer is shot because it should be able to accept 110v or 220v. Could it be anything else?
