I recently bought JP lost world. The plastic drop target broke shortly after. I replaced it. Then about 2weeks later the snagger started acting up. It would occasionally not work. Then it stoped all together. I did some investigating and determined it was the drop target not going down. I determined this by triggering the locks with the glass off, then when the ball is on the magnet I tripped the drop target manually and the snagger works.
So, I went into diagnostics and the coil will not function. There is 22volts at both terminals on the coil. I also tried to jumper the coil to try to make it pull in, it didn’t. So I determined that the coil must be bad and Put the game back together, to order a coil later. When I started using the game it started working, for a while and occasionally after that. Anyone have any ideas of what to try next.

The drop target coil does not trigger in any tests. The snagger test does nothing in test. The target reset coil works in test.

Here is a funny thing, even though the drop target coil and snagger don’t work in any tests or during the game, they world when the machine cycles to look for a missing ball.
Any ideas?

Yes, and I tested most of the other flashers and coils to be sure they were working. Everything else worked.
