I haven't had the issue but haven't had my machine for more than a few months either. I know those switches are really finicky so if you haven't already checked the switches with the balls try that. I'd be watching to see if it's bouncing back. Or simply one of the switches is flaky and is registering locked ball. I know many people replace them with the roller switches. Either way, bump for the veteran owners of the game that can offer some real help.

The right way is to get the Pinnovators kit. The not as good way but works is soldering/alligator clipped to the sub. I will say that having a PSW10 on CV sounds great.

Good call on the switches. They've seen better days anyway. "Your mother drives a dump truck!"

It's the first machine I needed to get one for. Especially with the color DMD. Really helps.

Looks really good and the mirror blades go well with the playfield. Ironically you mentioned about your back up post and I snagged mine when putting my playfield back in!

It goes in the spring weld meet in Ringmaster’s neck. It has the notch for the magnet and flasher lamp wire.

Found a picture for mine from when I was doing disassembly.

Correct regarding diodes. There’s sometimes other strings that may use other colors than yellow. Forget what common GI wiring is used on WPC95.
