Hi. Very new to this. Never done any pb stuff before (computer geek really). Trying to revive a wcs94 machine for a friend and I am stumped. Already had to replace the service buttons in order to run tests etc and to reset the machine as the batteries were very dead. The problem is that it is not firing the solenoid in the trough. Having run the tests solenoid 1 fires ok then 2,3,4,5,6(trough) and 7 fail then the ramp diverter (8) works. As far as I know all these are on the same high power circuit running via fuse f105. Even though logic said it cannot be the fuse replaced it anyway. Still same result. Any clues?? It also repeatedly fires a solenoid for 10 plus times on startup - could this be related?
