I recently found myself with a non-working Norton High Ball (this one), and am looking for some advice for repair. When I pulled out the transforner assembly I found some evidence of a previous repair job, but without the schematic I'm not sure how it should be fixed.
There is almost nothing to this board - it basically rectifies the 25VAC from the transformer, and distributes it to some connectors for the sound and light boards. There are also 2 solid-state relays that would presumably control the ball release and the ticket dispenser.
In this picture, I drew in pink where the diodes are. But the one shown in green was cracked, and split in two when I touched it. But since it was in parallel with the one above it, I'm not sure if it was cracked and hence repaired (without removing the original), or if someone tried to fix it but hooked them up wrong.
A full-wave rectifier would need 4 diodes, but installing them like they were previously wouldn't be right. But a half-wave would only need two, so why the extra? Does anyone have any leads to a schematic, or possibly some advice on what to try?
