Thanks. I found a simpler schematic of the push button PEB online and used that but this one is better in some respects. First Omega was right only one fuse in the PEB either externally in the push button or internally. Second, when I looked at the old schematic of the PEB it looked like the fan would not run if the fuse blows on the push button version of the PEB. That is indeed the case as current goes through the fuse prior to the fan in the old version of the PEB. This is opposite of the newer one. So next I checked transformer resistance and AC voltage going into the board and DC voltage going out of the disk drive connector. I got no values for any of these. This leads me to believe the transformer is not working rather than the two voltage rectifiers. I guess I have several options at this point.
1. Obtain a working PEB transformer and install it.
2. Obtain another transformer or power source that would work with the PEB.
3. Obtain another PEB and use this one for parts.
4. Part out the PEB on Ebay.
Any ideas about obtaining another transformer or alternate one/power source? I have no idea the winding ratio or how I would get 5 wires off a new transformer. Any ideas would be appreciated.
