Why not rebuild the flippers and replace the end of stroke?  Then you can have nice strong flippers, oh and clean the contacts on the cabinet flipper switches as well.

i agree. rebuild flippers, replace bush, clean flipper contacts on cab buttons and for a few bucks more replace the flipper coil. your flippers will be like new and work well for years to come.
once they get to a stage where you need to replace a bush or a sleeve they are due for a rebuild.
and as far as blowing a fuse goes you either have a eos or wire shorting or a crook diode on the flipper coil or the coil is cactus.

mark.c should have all these parts
