Quoted from Rotellicaster:New here.
After reading this thread last week, I decided to try and resolve my left flipper issue. I purchased some IRF540N Transistors and Replaced it today.
The original issue was it blowing a fuse at start up of a game. The flipper would go straight up and hold itself for 2 seconds then blow the fuse. After identifying the shorted transistor, I replaced it along with the fuse and All looked good until one push of the left flipper button and then, Stick, Blow fuse and a shorted transistor. What the heck?

Also check the coil resistance. See if the ohms are within specs for the coil.
