Hi All,
I am having a problem with my Williams Stardust score reels. The 10 and 100 score reels are not advancing the next higher reel. 10 to 100 and 100 to 1000. The 1000 reel is working fine. This is happening for every player which leads me to believe it is not the reels but must be the 10 and 100 relays. They were both working and then stopped. The 10 stopped working first. I cleaned the contacts nothing worked. At one point things started to work again, I am not sure why. I have been testing by manually working the 10 and 100 relays. Then I was testing it using the playfield and things stopped working again. Nothing has worked since. I am not sure what my next step should be.
I have included a picture from the instruction manual.

When I manually activate the 10 pt relay past 9 nothing happens to the 100 relay when the machine is on. If I reset the machine ready to play and go past 9 on the 10 pt relay the 100 pt relay freezes on and does not advance the 100 relay but the bell rings. Nothing happens with the 1000 pt relay.

Yes it does stay activated. I think it is in the 100 point relay. If I push it hard to activate is works. So to me that suggests one of the contacts is not connecting well. I tried to clean the contacts but still doesn't work correctly. I am going to give it another cleaning and see what happens.

The problem has been solved. One of the tungsten contacts on the 100 point relay needed to be cleaned really well and adjusted.
Thanks Howard for all of your help.
