    Hi. I'm putting my Strikes and Spares back together after a playfield swap. I have Alltek lamp driver and solenoid driver boards. When I flip the flippers the switched lights and the GI flicker, do it a couple of times and it blows 5a lamp fuse. It doesn't do it when the pop bumpers go so I don't think its a vibration thing.

    Any help would be appreciated.

    A lamp socket or wire to a lamp socket could be touching the flipper mounting baseplates.

    One or both of the End Of Stroke flipper switches might not be opening at full stroke.

    you say a 5A 'lamp' fuse is going open, but the 5A fuse is for the 43VDC being F4, for the coils.

    the 2 lamp fuses are F1 = 10A for switched lamps & F5 = 20A for the general illumination.

    check the voltage & amp ratings on all your fuses.

    Fixed !
    There was 2 separate problems, I hadn't gapped the the EOS and thats why the 5A coil fuse blew.
    I had 10 LED lights, when I swapped them out the flickering stopped. I checked the power hookup on my ALLTEK lamp board and I have it connected to the common side of the switched lights as they instruct, and I read voltage where I attached it. I have 4.9 volts at the transformer for the switched lights. Not sure why I can't run the LEDs.

    thanks to those who replied, saved me a lot of pain.
