I'm working on a customers Target Alpha and pretty much going through everything even though the machine is playing.
Check out the hack to the right flipper. They picked off the 24V and ran it through a couple blocks to the flipper button switch. Then they installed an A-17875 coil.
So, I'm scratching my head wondering why they just didn't replace the A-1541 coil that was in there? Maybe a 15 minute job tops if you had the coil?
The right flipper barely worked. So, removed the hack, placed a A-1541 coil, re-wired the flipper button switch, and now the right flipper is working great.
