Well the first thing that jumps off the page for me is why. V17 pin5 shows +117 when it should show -5 volts. There is something going on there for sure. When I get home I'll yank out my SAMs and have a look at that see if anything jumps to mind. But I do know that if a circuit is expecting negative potential and it's getting a huge positive there is something wrong in there.
