I originally had a 2-speed but they were too expensive at the time it failed so I decided to replace it with a single speed. Well the single speed is costing too much in energy so I bought a 2-speed and can't recall how it was wired (three wire setup).
I have green (ground), red, and 2 blacks. When testing with a multimeter, I tap the multimeter black lead to the green ground and the multimeter red lead to each of other 3 wires:
Black 1: hot (120)
Black 2: zero reading (assume this is neutral/common)
Red: hot (120)
The motor has connections for L1 (Hi), L2 (Com), and A (Lo). Does the Black 1 go to L1, Black 2 go to A (Com) and Red go to L2?
I'm attaching a snippet from Inyo Pools article on wiring a 2-speed like my AO Smith/Centurion plus a pic of my actual motor wiring.
