Quoted from schwism:Need some advice on my next steps.
When I turn the game on a SB fuse immediately blows and the rear GI does not come on. I am able to power the section with an alternative power source so I don't think I have a shorting issue. if J120 and J121 are unplugged the fuse doesn't blow. I checked continuity on the power board and everything seems okay.
Is it possible Q14 is at fault? Not sure where to turn next.
do you have leds in the game? could be a bad led. take them all out in that string and see if fuse blows. then add them back one by one. should only be a handful or so of them.
