Identify the supply lines leaving the power supply. E.g. in a modern computer you'd look for 5v, 12V and 3.3V. I don't know what the IWII has. Anyway, identify those lines and then check their resistance to ground. Perhaps there's a short somewhere from the broken metal bottom plate?
Other than that, try Larry Pina's book on Mac Printers. Ah, here we go:

"Macintosh Printer Secrets".
There are two main circuit boards in the IWII and having a spare of each on hand is a nice luxury which is challenging to achieve these days. But you might try Ebay or the LEM Swaplist or the Trading Post here. There may be someone who wants to dispose of an old IWII who is willing to part it out.
Oh, on ebay there's a seller who goes by the name olde Mac Milt. He may have an IWII power board.
