Hi all, I have a Black Hole with a single pop bumper problem. It’s the lower left bumper and upon power up it locks on and blows the fuse. The spoon switch looks ok as does the wiring. The PBB is brand new and swapping it makes no difference. Any ideas/assistance would be appreciated. Thanks

Does it lock on if the PBB is unplugged?

Swapped the PBB with yet another board and the problem is resolved. Now I’ve noticed that all the pop bumpers are scoring intermittently. Sometimes they register and sometimes they don’t. I’ve checked and reflowed the solder on all the switches and the problem remains. Switches are all adjusted and working fine. Stuck again, any ideas? Thanks

Just to clean the contacts

Contacts have been cleaned and still have the same issue with scoring. I ran through and tested all bumpers and switches and found that the upper right pop bumper works consistently however the other three do not. In addition, the gravity tunnel spinner exhibits the same intermittent behavior as the 3 problem pop bumpers.
