I am having some difficulties with a recently purchased lotr machine. 1. When the ball enters the gimli vuk on the right side it fails to be recognized, so assuming that is a switch that needs replaced and 2. then when it does the ball search and activates the vuk plunger only about 1 in 6 does the ball actually land on the rail, usually bounces back down. I have tried adjusting the coil power as it seems like its too powerful, but that did nothing. Any help, comments would be appreciated. Game located in Calgary.
