*Fixed* Need Help With Gottlieb Sinbad
Ken Layton:
The rebound rubber is easy to swap out. Just grab the rubber and pull straight off. You might need to do a little rocking action, but it should slide right up over the head of the riveted post.

**UPDATE**
So after messing with the power supply I realized I was reading the power out voltage wrong. I am getting +5 and -12 out to the Ni-Wumpf board. I started over only plugging in one display at a time, etc and now when I power on the game I get all displays working and it will display credits. All of the drop targets pop up on the table but the ball kick, flippers, chimes are not working. I took the playfield art off and most of the rings but the leaf switches to the drop targets, etc do keep score. Any ideas on where to start the diagnostic on those? All fuses including the solenoid fuse are working.

And here I've been saying it was a connector problem, and you got the damned thing booting by doing nothing more than reseating the connectors a few times. Told you so.
:lol
Did you check the fuse on the underside of the playfield?
urbecrisch:
Yeah. All fuses working... but last time I booted machine the drop targets didn't reset upon game start when prior they would reser whenever I would start a new game. Also, what's the best spray to use to clean contacts and best tool to remove connector pins? The tool I was using didn't work for crappy! Those connectors are hard to remove.

This and a wire brush:

You can remove the connector pins by pushing the tabs in the narrow slots with a jewellers screwdriver.
What you're describing sounds like dirty connections between the CPU and the driver board. That cable plugged in almost directly beneath the leaking battery on the original motherboards. Replacing the pins in that connector will probably fix you up.
