Parts have arrived to effectively finish off the machine. It has been a long haul, but I'm seeing light at the end of the tunnel !

The machine had some very weird wiring issues with the game. The chaser lights on the playfield around the top left hand bend and along the top were not right at all. This was difficult to diagnose and in the end, I had to pull out my personal Fathom to compare. Even then, I was left scratching my head. There were a lot of differences, so eventually the second populated playfield was the only way to determine the problems I followed the wires to the Aux Lamp driver and then re routed them to the correct locations. Effectively the GI returns were not wired correctly for that part of the playfield, but i worked it out in the end. I ended up replacing sections of the GI return and the feature lamp returns. Interesting problem.

Here's the back section of the playfield. Impossible to work on without removing this VERY heavy playfield.




Fixed ;





Rewiring the left section at the beginning of the chaser light effect ;





Some power supply issues solved !





This rear glass channel was broken. Both tabs were broken off. I had MartyJ skillfully TIG weld the ends back on and then I had it chrome plated. Looks better than the picture !





Now I see this ALL THE TIME with playfield swaps. Literally, the playfields are swapped over without checking the assemblies etc..





As I dig deeper.. I find more issues. Wood screws were there should be metal screws and visa versa !








Here is a repaired ball shooter assembly part found on early 80's Ballys. Next to is is the last known NOS part to replace it..  #@#





A rebuilt drop target assembly. These are crucial to the game. If these don't work properly, then the game become inoperable.





The apron is repainted and a decal installed from PinballRescue.





The game plays well but needs a few minor adjustments. Almost there !

Just waiting on some new clear lane guides and we are almost ready.
