Thanks, macrocircle. I did double and triple checked my connections and I couldn't get it to run (3 wires to motor and 5 to controller). However, I didn't really didn't mess with the black wire coming directly from the hub. It looked fine when I unpacked it and it has a coiled spring thing around the base so I didn't think it came loose.
I can't test the hub anymore since I shipped the controller for them to test. I don't have a problem opening up the hub, but they tell me they will honor the warranty on the hub, so I don't want to take it apart. I'd rather let them do it. If it was a few years old and out of warranty, I would have already opened it.
