Suddenly the bumpers and sling shots stopped working, after cycling the power they would work again. Now a month later they have stopped working completely. I haven't looked into it yet but any ideas where to start would be great.
Kind of odd, maybe more than one problem. There's a 2A under playfield fuse for the slings, this also feeds the popper kicker, so if the popper kicker isn't working either you might check that. The bumpers are fused separately with all the other coils in the game, so it isn't likely unless none of the coils are working - that's a 1A under playfield fuse. After checking for +43VDC at the bumper coils, I'd check the connectors for triggering at the CPU. The bumper triggers from connectors at the CPU board noted on the schematics as follows:
CJ8-6 Right bumper
CJ8-7 Middle bumper
CJ6-4 left bumper
I checked the fuses last night and there all good. The popper kicker still works. I'm gonna look into it more tonight.
Fixed!! It was the CPU connectors. Had 3 or 4 that where extremely loose. Thanks wayout400
