So, I'm thinking I have an intermittent short somewhere. At seemingly random times all or most of the lights go off for about a half second. When I first got the machine this always happened when I hit the orb, but now it happens more often when it didn't before and doesn't seem to correlate to hitting anything specific. Sometimes it happens on the plunge, including the Nova Core lights so I don't know which is lit for the skill shot. Sometimes it's just during normal play, shooting a ramp or whatever.
I've gotten an overcurrent error on Node board 9 on startup I think 4 times, twice it's stayed on the error and didn't finish booting, and twice it paused on the error then continued to boot.
I've disconnected most of my mods one at a time, tried turning off the shaker and tested and haven't stopped the problem yet. I found a bad GI socket, the rivet is super loose and the whole socket flops around so I disconnected that for the time being. I'm not sure how to best troubleshoot since if it's a short it seems to not be happening most of the time so checking stuff with a multimeter doesn't seem likely to see the issue since I can't reproduce it on demand. Sometimes it happens a lot in a single game and sometimes I can go a few games without noticing it.
I'm really skittish about damaging node 9 or 8, since replacements for those likely have the new chips and require new code that I want to avoid. I appreciate any ideas for how to troubleshoot this safely.
For a sanity check, I think the original "lights out" when hitting the orb is normal, am I wrong about that? When is it normal for the entire playfield to go dark for just an instant during play?
