Gottlieb System 1 Switch Problem - Sinbad

[Brettski]

Howdy,
Sinbad is up and running quite well except I noticed that none of the switches behind the rubbers on the playfield work.
The ones I am referring to are all the low score switches under the plastics behind rubbers but not the bullseye targets.

Any idea where to start checking, it has a wumph mpu and rottendog driver board.

Cheers: Brettski... :)

Not sure about the aftermarket boards, but if you can run diagnostics to determine exact switch numbers that are faulty it might help.

Probably a connector

Oh no not again! LOL 

My Sinbad ones look reasonably fresh but that means absolutely nothing I know! ;) I have a new crimper on the way so I am going to crimp every connector in both Sinbad and Cleopatra then I guess we will see what happens and I am sure you are right again! :)

Check all of the switches are adjusted correctly.  If one of them is constantly touching it will knock the rest out from memory.

Agreed, this is common when people replace rubbers.  New tight rubbers and all it takes is one switch to be closed and all in same row or column won't work

Thanks for the tip, it is very possible so I will have a good check..

Much appreciated..

Spot on Guy's, Stuck switch..
Also thanks to Andrew (Beaky) the credit knocker now works again, rubber stop was missing which made the rod fall too far and then unable to pull up when energised. New Step Down also added in. Sinbad is now like New!! Loving It!!
