Picked up a Bally Harley Davidson today. Plays well, except the ball often doesn't kick out into the shooter lane. The solenoid sounds strong, but I can see the ball sometimes just barely launch, then sometimes hang on the edge or sometimes get into the shooter lane. 2nd issue is with the 2 displays. The left one is missing the upper right segment on all dozen(?) characters and the left display is missing the top segment on all characters. Reseated cables and switched cables between left & right displays. Any ideas. Thanks.
