Two new projects


I have two new projects to work with, a Stern Sharkey’s shootout with battery corrosion at the CPU board and a Sega Baywatch with a few faults. The trickiest one is that it sometimes ejects two balls in to the shooter lane. I think that I am on the track of the cause of the fault and the problem seems to be the switch for the fifth ball in the ball trough assembly. If I keep the switch closed with while the CPU are ejecting a ball to the shooter lane then it also ejects a second ball. So it seems like this switch sometimes does not open up as it should when the ball rolls off. There is also another problem with the same switch, sometimes when the ball drains it’s not detected by the switch and after a while the CPU starts a ball search and the vibrations from the solenoids make the switch to close and the ball is detected. A new switch has been ordered and are on its way by post.
