Hi d8veh,

The test I have just done sounds similar to yours, and was suggested by Neptune following testing with a multimeter, and then with a "brushless motor tester". He also suggested a final test connecting one lead of the test lamp to the motor casing, and the other to each phase wire in turn.

The connectors for the halls and the phase wires are all in a single 8 wire multi plug, so no mixing up.

We are currently letting the motor dry out completely on top of a radiator for a few days.

Thanks for your input

Where are we now? I can't understand the test you've done and it's too much to read everything again. Try this simple test: get a torch bulb and join two wires to it; connect the ends of the wires to any pair of phase wires; hold the axle still and spin the wheel backwards. You should see the bulb pulsing light. The lower the voltage of the bulb, the brighter it should be. A 1.5v one would be best, but don't spin too fast or it might blow. Repeat for the other two pairs of phase wires. If the phases generate, then they'll work as a motor.

Next check the hall wires 5v supply and each phase should pulse when you turn the wheel backwards. If that's ok as well, then you only have to get the phase wires and halls in the correct sequence. I guess you checked the colours accross the connectors.
