I really thought I was on a winner here. Great advice by Dan lead me back to the solenoid connector with two loose contacts on the connector. One for the Ball release and the other for side saucer kick out. Changed the whole connector and all contacts and made no difference. Bloody annoying.
I tripped the ball release a few times to run few balls though and see what happened but with the change I made to the switch wiring this morning it just wants to keep kicking both balls out so I still think the wiring was correct the way it was before. When the game was working it certainly worked that way.
Picture below is of the connector before I changed it over. Hard to see but the two top contacts are loose and bent over almost to the point of falling out.
