This is probably a dumb question but I'm still new to actually repairing machines so here goes anyway.
I popped open the back on my new nonworking Space Zap recently and was expecting to see the bally/midway psu A082-90411-A000 but instead the psu said A082-90411-C000.
It looks identical to the A082-90411-A000 but I wanted to make sure as it had two caps daisey-chained together that had popped installed the opposite way than they should be according to the map I found for the A082-90411-A000.
I've since replaced the two blown caps with a correct single cap with the orientation dictated by the above-mentioned map but it only made a little difference. My marquee now lights up and I get junk on the screen.
I've checked my voltages at the comm motherboard at the bottom of the board cage and they're good except for the -5. For the -5 I am getting positive (+) 5. I'm planning to use the rest of the psu repair kit I got from Bob Roberts but I was just wondering if this issue is tied to a specific spot on my psu.
Anyway, I got off track. Are these two PSU boards the same? I assume they're just different revisions.
