On a 8 ball deluxe whilst in a 2 player game it decided to jump from player 1 to player 2 as i launched ball 2. I've gone into sw test and it gets even more bizzare. If i'm holding the ball and move it over a rolloverwire switch it fires a pop bumper.Three of the switches fire pop bumpers, one fires a sling. This applies to the 2 inlanes and the 2 outlanes. I've checked the 4148 diodes on these switches and they read as good. If i press the switch with my finger it works fine. It's like i'm grounding the switch. Any ideas anyone
