My ringmaster stopped registering hits a while ago so I ordered the auto-eddy board from Pinbits. It still didn't work so I traced the wires and it turns out the ground wire to the board has a disconnect under the playfield that had gone bad. I replaced the disconnect with a single crimp connector and tested the eddy sensor and now it works. Perfectly! In switch tests. Once I start a game the eddy sensor stops registering hits and the game says "Check top eddy sensor". I checked the driver board and it's got voltage at 139-2 like it should during a game.

I'm at my wit's end on this one. It was a short trip to be sure but any help would be welcome.

One thing I noticed with the Pinbits board is the label silk screened on the board differs from the stock Bally eddy boards. The pins labeled Row & Column are reversed. I checked the original board in CV & the 3 boards in my ToM and they are all the same. Do I need to swap the wires? Could it still register the proper switch in a test then fail in the game because of that?

Judging by the overwhelming response I guess I'm the only one who didn't set the "Use Manual Eddy Sensor" setting. Thanks to Martin at Pinbits I'm up and running. Their website shows that board out of stock if you search under Cirqus Voltaire but it's the same board for several games.

Funny story.

Tonight i got sick of my Ringmaster not registering hits. Same problem as above. I Google it. I hit this thread. I check my settings and sure enough, it was set to auto-eddy. Set it to manual and its perfect again!

Anyone else use Pinside to store repair notes?
