I'm having some really strange problems on an Addams Family pinball, and any
help would be appreciated. I read around at Clay's site, and thought I had
it figured out, but no dice!
Anyways, the first thing that happened was the bottom right flipper went
dead. Checked the fuse, it's blown... replace the fuse, turn the game on,
and the right flipper sticks up (electically, not physically), it blows the
fuse again, flipper falls back down.
So I read on Clay's site that this is probably the 36c transistor, and
possibly the Tip102 before it, so I checked the 36c, and sure enough, it was
shorted closed. I checked the tip 102, and it too showed shorted, closed.
So, I replaced the 36c, then rechecked the tip102, and it was fine...
apparently the short reading was because it was connecting through the
shorted out 36c?
Anyways, plug the game in, everything's fine, but when you hit the flipper
button, the flipper sticks up, until you hit the left flipper, then they
both fall. Eventually, BOTH left & right flippers slowly rise up, and then
when you hit the button, the left fell, and the right stayed on until it
blew the fuse again.
Checked the 36c, again it's shorted out. So, I replaced the 36c, PLUS the
Tip102 driving it (which showed shorted, again)... also checked the coil,
and the coil on the bottom right flipper had 1 diode missing. Replaced the
coil, with one with 2 diodes, as it's supposed to have.
Plugged the game back in, it's doing the same thing, both flippers slowly
stick up in the middle of the game, one will stay up until you hit the
button, etc... eventually after a few seconds (30 seconds of play?) the
right flipper sticks up, and blows the fuse, AND the 36c transistor.
Any ideas of where to look next?
Thanks,
Ron
