Finishing a PF swap. Among other things, I replaced the left flipper assembly. Everything is working except Thing - I'm working on the OPTO board - and the flippers. In flipper coil test, everything works except the left flipper. When I run Left Flipper power, everything goes black for a second and the game reboots. I'm guessing I've rewired it incorrectly. All fuses test good out of circuit, and as everything else works, I'm confident I've got everything connected properly. Can someone send me a pic of the left flipper wiring?

Thanks!!

Be sure diodes are facing the right direction.

Thanks, Loyd!! Rewired and flippers are working in test. However, they still do not work during game play. Any ideas appreciated!!

I'd reseat ribbon cable from CPU to Fliptronics board next.

After that, you got me stumped. Then either signal from cpu to fliptronics board, or fliptronics board has an issue.

Well, I managed to make things much worse. I’d pulled Thing out to clean the Optos and reflow the opto solder joints. Thing cover sitting in the bottom of the cab. When I reseated the ribbon cables and tried to test the flippers, the line fuse blew on power up. I’m assuming the thing cover shorted against something, because removing the box and replacing the fuse got the machine to power up. However the ‘good boot’ tone and cpu LEDs are inconsistent and the DMD is scrambled.
Crap.
Next steps on isolating the culprit(s) are greatly appreciated!

Whew...looks like I dodged a major bullet. I isolated the CPU, which booted fine. Boots fine with everything else but the DMD controller connected. Check out the F602 fuse.

It actually tests OK out of circuit, but I think I’ll replace it anyway, assuming I can find a 3/8 amp fuse around here somewhere. Worst case, hopefully, new dmd controller.
