Thanks for posting the updates on your Phantom Gun project. There is rarely much information on how to repair and troubleshoot some of the gun games so I always am glad to see someone posting something like this thread.
I have two EM rifle games and an EM driving game that all need some work. My 1967 Williams Arctic Gun was at the TPF last year and was having trouble registering a hit on the running bear target but was working otherwise. My 1974 Chicago Coin Fun Land Rifle game was mostly working but after moving it from Oklahoma to Texas it developed a few issues that prevents it from being played right now. And last weekend I picked up a 1970 Chicago Coin Speed King EM driving game that I will be working on over the next week or two trying to get it up and running. All of them are up on movers dollys right now but the EM gun games will be getting swivel caster upgrades very soon.
