Default Sinbad

I just purchased a Gottlieb System 1 Sinbad and have no experience fixing machines but I'd like to learn. That being said, it starts up with the 5 second delay but doesn't click. The playfield lights and flippers don't come on.
After reviewing videos and other feeds, I checked the fuses and they are good. Both slam switches are closed, the pendulum is not touching and the tilt on the side is open.
The tilt relay stays pulled in when it starts. If I have the game on and pull it out, everything works. As soon as I let go though it pulls back in.
Any suggestions???

If your machine has its original boards then you can try unplugging the CPU and driver boards and cleaning the board edge connectors with a pencil eraser or a Scotch Brite pad and finish off with a napkin to wipe off the residue. Next check the slip on connectors for loose wires, and corroded connections. Pinrepair and pinwiki both have some good repair tips for system I gottlieb.

Default About Those Switches ?

Those slam switches are normally closed on system 1(Pretty sure, anyway) And that rolling ball tilt switch is supposed to be closed too. If your displays light but flicker your game may be in 'Slam Mode'
P.S. Please let me know if I am wrong about the proper state of those switches...C_S

Thank you so much for the tip on the connectors. I cleaned them with an eraser and plugged back in and it worked!
