    Thanks, that actually explains some behavior I’ve been seeing quite well! I confirmed that D5 was showing up as shorted, and after removing it U5 and U6’s inputs no longer show as shorted to ground with either switch position.

    Is it safe to do a test power-on without D5 in place? I’m not the best at circuit design, so I could be completely wrong, but it looks like it’s just there to prevent damage in case the wrong polarity of adapter is used?
