Results from the meter test. I get good continuity from everything EXCEPT P1 down. Triple checked the colors just to be sure. Must have just had the harness sitting funny when I had those color issues that day. Will double-check hooking up multiple PCBs to the MK30 this weekend to confirm that there is no color issue. Looks like my problem is P1 down then. Guess I need to lift some of this epoxy and resolder the connection.
