Bafang/crazyman - the continuing saga....
OK I've been talking with Knuckles on the email and it all got a bit confusing so I dedcided to run all the tests again - There's a new spreadsheet of (intriguingly different!) results available here http://www.oddjones.com/docs/PHASE-HALL-ODDJONES-2.xls This time I made sure the motor was in the right way round and the right way up, and I wired a 5a fuse between the battery and the controller (well, ten of them so far - they kept blowing!)
I'm conscious that it's really difficult to get across exactly the problems in text sometimes so I've posted the following videos to hopefully get to the bottom of the situation...
1) - This is what I mean by "nudging the wheel backwards"

I also took the time to run gip_mad's suggested tests on the motor again - with different results...
2) - Phase wire resistance - last time I realised I was measuring the resistance across the HALL WIRES not the Phase wires...

3) - Hall Sensor test -

So - what do people think? Have I fried my motor? -
gip_mad said:Your throttle seems to be connected correctly, if the color matches... and the wheel spin. At this point, I would try to check if the motor is defective... First try to measure resistance between every combination of the phase wires: it should be the same. Then, power up the rig, and disconnect the three signal wires from the hall connector. leave the red and black wires connected. Measure the voltage between red and black, ther shoul be at last 5V. then put the black wire of the tester on the black wire of the hall. with the red wire from the tester, measure, one at a time, the three hall wires (thin Yellow, green, blue). They should alternate from 5V to 0V when you slowly rotate the wheel.
Does anyone have some other suggestion?
