Anyways i'm going to order a new coil for it.
Just wonder if there is anything else that can cause this problem as all 4 coils seem noisy but not close to bottom left one.
Thanks
Check the diodes on the flipper coil, I have had lots of these busting off recently. Also, the driver transistors frying.
