Picked up BSD with some issues, got most worked out. Only thing left is the magnet for the mist multiball is being weird. I replaced all the optos as they were old and yellowed, afterwards I got the unload test to carry the ball all the way across and back to the middle before dropping the ball once. Now it just makes it half way and drops it for the unload. for the load ball test nothing happens. Going to start rebuilding the boards under the PF unless someone has a more pointed suggestion.

Also, occasionally if I have the glass off and happen to touch to metal parts at the same time, like the rail and the metal ramp, I get shocked. Looked all over for a grounded out wire but haven't found one yet.

nothing happens = after it unloads the ball and get to the load magnet test, instead of a ball poping out and the ramp lifting up to fire a ball up to the shooter lane side opto, it just sits there doing nothing. The ramp lifts and when you fire the game up so I don't think it's bad.

As for the shock issue, I found a coil that has partially unwound, but nothing else (see pic) would this cause the issue?

also,
If I put it in switch test in the menu and block the optos with my finger the ball holder one seems to open and close, but the long range opto (one on each side of the PF) doesn't show any activity when I block it. I've already replaced the emitter and receiver.

Awesome, was just reading about L1 in the pinrehab article. Ordered the homepin board, I'll let y'all know if that resolves it.

Can someone chime in on that pic of the unwinding coil? would that cause my electro shock issue (only seems to happen when I touch two metal objects on the PF, i.e. rails + metal ramp, etc.

you can't really tell from the picture but, the coil wire that has loosened up is touching the metal bracket behind it. Ordering a new one. I'll be back if that homepin board doesn't do the trick.

Sweet, that worked for the stuff on the left side. Then I found one of the wires from the launcher solenoid was touching the bracket for the stuff on the right side. Now just have to wait on that card and see if it resolves my issue with the long opto. I'll replace L1 and test it (to keep as a spare) on the existing card to confirm that was the issue as well.

Home pin board resolved my issue. Still have to figure out why the castle lock 2 opto is going off randomly though, about to replace the opts up there since they're the only one's I haven't.

Fixed the castle opto, connector in the wrong place on the cpu board.
Plays perfect, only remaining issue is the coil for the 1 drop target in the game fires 3-4 times randomly even though the target comes up on the 1st fire. new microswitch didn't resolve the issue. only happens when you complete video mode anyway so not that often...
