I have replaced a lot of the 1.75 mfd caps with the 1.5 mfd caps and they have worked just fine. 

The wiring has actually crossed my mind. I went by your 77646-AS notes. I felt the wiring was likely the same as the switch/coil layout is the same. My resistance readings were different than what you provided in the 77646-AS diagram (around a 30 ohm difference on all three), but I felt that was fine since it was a different series, larger fan, equal difference across all three leads, etc. I was confident I wired it correctly, but it’s definitely worth double checking.
