I recently picked up a Game Plan Old Coney Island! Game is not in bad shape, and plays pretty good, other than all of the switches in Line 5 of the schematics. The solenoids work, as I watch the top right bumper activate. However, in switch diagnostics, none of the items in line 5 do not work. The MPU is in good shape; no acid leakage, and I removed the old battery. Connectors And solder all looks Good. I’m a bit baffled. New to fixing machines too, but pretty savvy with technology.
