I will answer the questions and some thoughts in this reply and then again as more come in.
Yes, it is a Hall sensor. Looks as though most are thinking like us and that it is something with the magnet sensor alignment/distance so we will check that first.
It is also possible we didn't rock the prop fast enough at #1 TDC....very likely as well.
We will test pins 1 and 9 again...just in case we counted wrong.
Good idea on passing a magnet over it and good to not to connect a VOM. Thanks!!
