When going through the Fireball machine for the first time, I noticed some cut wires down the right hand side of the cabinet. I made a note of it and moved on. Only later did it occur to me I couldn’t find the knocker.
I went back to those 3 wires and noticed a small metal plate against the side of the cabinet. So this is where the knocker -used- to be. But for some reason, it had been removed.
I asked around and eventually managed to secure a complete original Bally knocker assembly. I could have used an alternative, but thankfully I scored a Bally one suited to Fireball.
The knocker was a bit dirty, so pulled it apart to give it a good clean. They are a pretty simple assembly. The spring was a little rusty, so i’ll replace that and also give it a new coil sleeve.
With it cleaned and back together, I installed it into the machine and connected the wires back up.
Lastly, I fired up the machine and went into the diagnostic mode to test the coils. Coil #11 is the knocker and it fired off right on queue. Easily sorted 🙂
