I picked up a 4 slot cheap and it powers on but no carts come up. I can see its a pretty easy fix, the battery leaked and corroded the sound traces and also several traces leading to the top board. Problem is, its difficult to determine which traces lead to which pin on the connector. A schematic would make this a easy job, has anyone seen one out there? I poked around on google and didn't see anything.

Thanks!
 
Follow the traces... there are no schematics for a 4 slot.

I may have some stuff in my repair logs that could help.
 
Man, this scares me. I gotta send my 4-slot board to you CM before it's too late! :)

Take it apart and take the battery off the board. It's easy to replace most of 'em with a coin cell and battery holder. You just have to remove a resistor to disable the charging circuit.
