If the motor does not spin when 4 and 6 are linked, it could be due to a controller fault or a break (or short) somewhere along the thin red wire which runs between the controller and the socket.
Well done Karen,
good to hear you've manage to locate which of the suspected faults it actually was, and it's even better that you've been able to get it to work properly.
I hope it's not going to be too much hassle tidying up the wiring, and it would be nice to see some pictures of the finished result.
I still suspect that the motor is only running at half speed
And jikes! Iff that half speed, I might need a bikers helmet and suit...
I hope you've ordered that helmet and suit now.
AlanP.S. The next time I need help finding a wiring fault, guess who I'm going to turn to?
