Modifying to Torque Sensing

[saneagle]

Will I break it if I get the wires round the wrong way?

No, it's only 5v; however, if you leave the 5v wire connected to ground for a long time, it'll eventually blow the 5v regulator in the controller.

Thanks saneagle. Throttle now functions as expected and I get rotation of the rear wheel. Now looking at the feed to the PAS. I assumed it would be a reed switch but i am measuring 5 volts wrt to the other two pins and also slightly negative. What is the device please? I had no idea that Hall effect detectors were so linear. 1% or so.

PAS is also Hall effect.
The pulses between 5v and Signal to activate movement as the magnet disc passes the Hall Sensor.
