Left flipper was fluttering

Turns out he screw on the EOS switch was longer than normal and had made contact with coil windings. Replaced with shorter screw.

Games doing random stuff during gameplay,
their are 10 pin resistor/capacitors on the board called SIPs these can fail with age and do all sorts of strange things to the game..
