Try disconnecting the flipper opto pcbs and see if the ball search and flipper up still happens. When the flippers go up is just the hold coil (easy to move the flipper) or are they hard to move? If they are easy to move, EOS is probably OK. Then there is the question of why did your coils melt in the first place? Was it left unattended and you came back to that or did they melt while you were playing? Are the EOS switches working correctly? Are any of the other opto switched mechs acting strangely? (12V to the opto pcbs)

Flipper button opto boards. Inside the cabinet, look at your flipper buttons. One on each side that the flipper button activates.

OK Glad it's working that is a pretty common connection problem, it will likely happen again. Just for your info the flipper opto boards are attached inside the cabinet at the flipper buttons. Most WPC / WPC95 games use these, plastic or metal flags actuated by the flipper buttons engage opto switches which turn on the flipper coil. Sometimes you may need to clean these optos if the flippers get weak.
