I get 19.5K between those points.
What chip/component failure causes xmas lights? I can't find anymore broken traced mistaken connections.
That sounds about right, still like to have another with a full board compare it though, just to be safe.
I'd have to say better than 75% or so of the components on the board would give you the 3 strikes and FRAG symptom if they failed, so it's really hard to pinpoint. Being that it was a botched modchip install, I'd have to say the MCPX or the Xyclops is probably shot, but it could really be just about anything. Solder bridge somewhere, bad solder joint, ESD.
That LAD0 point (at R7P4) on the bottom there has a trace in the middle of the board that goes running to the MCPX, check and make sure you have continuity between these points as well as to that 3rd leg of the IC where ya started the repair.
