Hey guys
Well, I am having some interesting issues now. Started a recap of my SX 737 and started on the protection/power supply board. Got a few caps in a and had one with a bad connection, popping the main fuse. So I of course got the capacitor bridged, installed the new fuse in the screw in holder, and gave her a whirl. Nothing. So I start checking things out and I notice the inline soldered fuse leading to the screw in fuse is blown. I change it out, and success, the unit fires up and works like a charm. Then I start again working on my recap, I replaced one of the 50v 330uf caps (the one closest to the back of the unit of the three), POW! there goes the screw in fuse again. I checked the solder joints, those came out fine, then I noticed that while I had the board out of its connectors I had the back wire post on the right side (from my angle from working from the back) very close to the chassis. Ok, so I readjust the board accordingly, pop in a new fuse, and success again. Well then I power the unit off, then power it on again immediately. Zap! There goes the inline fuse. :screwy: I cannot see anything visually to cause that, and I have no idea what is going on, or what I possibly did. What do you all think? The whole popping fuses thing is confusing as hell now :saywhat:
