    During mardi gras we were playing the f-14 and all of the sudden I noticed the top left flipper was stuck on,and the smell told me the coil was heating up.
    After a change out,I don't have many coils working.There are a few,but the flippers,outhole and kick back and save coils are not.
    Not sure my schematic what to look at first. I'm thinking a transistor.But would 1 drive all these coils??
    All fuses have been double checked.
    Any help always appreciated

    sounds like you blew a fuse or took out a rectifier
    check F2 out of circuit

    Yeap. Not only checked it,I changed it to make sure.
    Thinking I have a bad transistor,but not sure where to look.

    If it was a transistor, you would only have 1 inop coil. Flippers of that era are not transistor driven. look on page 59 of the book or go to IPDB and download the manual. if you have a meter you can check the voltage at the coil
