Hey All,
I've been restoring a Stern Nine Ball and have just two remaining issues.
The first is that the left slingshot bumper won't work. The solenoid fires during the test, so this must be a switch issue. I've traced the wire back to the connector on the MPU board and all seems fine. Any suggestions on what to try?
The second issue is a bit embarrassing - this pin has a non-active pop bumper and I need to change the bulb. Problem is, for the life of me I can't seem to figure out how to get the top cap off. There are no screws. I would assume it's just held on with friction or I must be missing something obvious. Any ideas?
Thanks
Resolutions:
The cap was glued on - had to partially crack it to get it off.
One of the sling shot switches had a short - while fixing another connection, some solder dripped onto the base of the leaf switch (across the non-conductive spacers) effectively shorting the switch in the closed position.
