Thanks Ron, I think you may we be right. The player 2 works perfectly and there may also be something up with the credit wheel leaf switch too. This will benefit from disassembly this weekend and having a close look with the schematic on a big screen.Assuming it's just to one score reel that keeps spinning,? The score reel will have a few different switches on it, one of which will be the zero position switch that lets the game know when it's reset back to 0. I expect this switch isn't being made so it just keeps going forever.
Compare the switch positions on one of the working reels to the non working one and you should be able to spot the relevant switch and adjust it
Not sure about a Williams reel but if it's anything like Gottlieb and Bally then it's probably have the following switches:
- Zero position - tells he game when the reel is at 0
- Nine position - tells the game when the reel is at 9
- Run out switch - tells the game that the reel needs to be advanced to reset
- EOS switch - stops the coil from locking on (not needed for the game to work but obviously safer if you leave the game on and unattended)
High tack means its sticky, so will be more likely to take paint off, better to use something low tack.White and blue done on the left side...time consuming stuff this. Bought some Fabsome, high tack painters masking tape. This stuff does take the old paint off within seconds of use, but, it does give an amazingly sharp line.
