As an update, I flipped the magnet donut. It now attracts the ball. I believe it is working... kind of.
Thanks to LTG, I was able to turn the volume all the way down to hear when the magnet is charged. On the skill shot, it seems to charge only after the ball is past the magnet. Some modes going into them the magnet is charged. And when you light the left inland for magna it sometimes -- not all the time -- tries to grab the ball right after the inlane is pressed. So it never had a chance for the ball to get up there.
The magnet test activates the magnet going into the test, but after a second the magnet is no longer checked. So rolling the ball up the right orbit activates the right orbit switch but not the manget. I'm running LX-2 code...
I've gotta read the manual to figure out where this is plugged into on the boards so I can test continuity per LTG.
