Thanks again for your reply ..... Might of sorted it. When the first coil decided to fry i replaced it with a second hand one i picked up locally ,( new ones only in the US ,it is a AF-26-750/31-900) . It would appear that the replacement has its own little problems. I mounted it on the other flipper and the good one on the side where i was having problems and the good coil over to the bad side. The fault followed the coil. The side where I was having problem worked perfectly. Looks like i have to import some parts from the US. Thanks again for all your efforts. I will let you know how it ends up. Regards Paul
