    F116: Shorted bridge BR5 or shorted motor or shorted opto light or other 12 volt device on playfield or backbox, or even some Dot Matrix displays

    Quoted from LTG:

    If you like blowing shit up, go for it.
    Me. I'd pull the driver board and put a meter on bridge rectifier 5 and see if it's shorted.
    LTG : )

    Yep, start with the basics- check to see if bridge is ok

    Looking thru manual there are a bunch of 12v devices at J114, 116, 117 and 118.

    If you can get a circuit breaker to attach to spent fuse corpse it'll be handy.

    Glad you found out the issue.

    Lighted flippers? Is that a mod? Iā€™d get more fuses first and maybe a fire extinguisher

    Not familiar with everything TOM if any other devices use those solenoid circuits. Maybe ask in the TOM club or check schematics/manual.
