    Hi all, I have had a Target Alpha for over a year now. Installed LED’s when I first got it. Just noticed tonight that while the game is off, some of the LED’s are slightly illuminated .They completely turn off when I unplug the game. This is the first I’ve noticed it. Is this normal? Anything to worry about?

    Did you use non-ghosting LEDs? If not, that will likely fix it. Regular LEDs can light up slightly like that, or flicker on when the score motor/relays are running.

    Quoted from frenchmarky:

    I did not. That explains it. Thank you.

    If you're saying that the LEDs stay dimly lit, even when the power switch is turned off... then ghosting/non-ghosting will not matter.
    Sounds more like you have a electrical/floating ground/bad AC outlet/house wiring issue.
    There should be zero voltage going to any wires beyond the main power switch on an EM.
    Worry... mildly, yes. (Get zapped between two machines, or from metal side-rails to some other nearby plugged in device.)
