OK, I have been logging my WB in HPT for over a year now without problems. All of a sudden it is reading 0V. I unplugged the IO cable and measured with a V meter and was getting the correct readings. Connected it would read 0V though. I moved the input and ground to other pins (respectfully) and it does the same thing. I am at a total loss here. Any advise is appreciated. Another note, the gauge reads just fine. So I feel I can safely say the WB is fully functional.
