I just finished cleaning up my Diner and rebuilding the flippers. Before the rebuild, the left flipper was weak. I replaced the coil with a new one. All new parts, including flipper bushing. There is no mechanical binding, the flipper starts off strong, then during game play the coil heats up and loses power. I checked and it has 65 v =/-, which is the same as the right coil. I checked the wiring schematic and it is wired correctly. The EOS switch is working properly. What should I be looking for?

The Fuse Connector for the Left Flipper had a cold solder joint (on the auxiliary power board). I re-flowed and added a bit more solder and it works perfectly now.
