Changed the magnet sensor and verified through menu that it's working properly. Checked the monkey rail to be sure no obstruction and lubed with lithium grease. So all menu tests work properly. The rollover on the left and right instigate the monkey and it comes down just short of touching and returns to the castle without the ball. So frustrating. I am at a loss on what to do. Wires appear fine. The sensor is doing it's job other then it seems like it let goes a little early. The Monkey test goes to the bottom at 1.77 seconds. Evevrything works in the menu test but fails during the game..WEIRD and JJ is not been very helpful. Any ideas? Thanks.
