Quoted from Mikespinball:

I had an issue with the volcano kicking balls out whenever it wanted to. Did alot of diagnostics and came to the conclusion that there was an issue with the CPU board. Sent it in for repairs. It came back, worked for awhile and the issue came back, but worse. All seem to check out okay with the volcano in switch test. It puzzled me. I finally rechecked the optos on the volcano. They worked, but were very dim lite compaired to the trough optos. I then replaced all the transmitter and reciever optos for the volcano and have never had another issue.
Might check your volcano optos as they could be your problem.
Good luck,
Mike

Quoted from The_Pump_House:

Trying to dial in my Congo and the only place I'm stuck is on the map hole. I sends the ball to the top post of the right slingshot and I would like it to cleanly move down close to the face of the right slingshot.
The coil, sleeve, stop ect are all clean and in good condition. The ball eject, like the mystery hole, is a pretty soft hit from the coil. During coil test the coil fires much harder (albeit too hard) and sends the ball on exactly the path I want.
Is my playfield too steep?

Quoted from KilaOhm:

Thank you. I’ll start by cleaning them and move forward from there. Any insight about the diverter in the volcano orbit lane? Should it only be up when the lock is lit?
