So I got the game... and I'm pretty pissed that it's not working as great as the guy said. The drop target was missing an entire assembly to make the target fall. Furthermore, the little mini-coil was burned to hell. I am replacing all of that. Secondly, the spinner needed adjustment (typical). Thirdly, there is no plastic covering the left ramp, so when I hit that shot with my (now) rebuilt flippers, the ball flies out of it. Combine all this with about 20 bulbs being out. A few I can understand. 20? WTF.
However, I can handle all of that (but that drop target assemble being totally absent pisses me off). I've owned many pins in the past. What I can't handle is the hand magnet. Ah yes, the magnet. I have totally removed the old wiring and replaced both magnet and switch wires with new, tougher fresh ones. I've owned a STTNG, so replacing wires on moving parts is familiar to me. No big deal at all. I checked the switch with a ball... it is SOLID. No matter where the ball sits in the hand, it registers.
Here's what's happening: The game plays great. GREAT. About 10 minute or so in, the magnet starts to get weak. It does go out, because you can hear it's still on if you get close and put your hand on it.... but it just runs out of oomph. It's trying, but can no longer hold the ball.
Now somebody, tell me... WTF is this? I've done tons of searching on the subject, and nobody seems to have an answer to this issue. I've fixed all wires, checked them well... the magnet just loses power enough to hold.
