You are making us guess with less than you have. Can you tell what scooter and controller - maybe a link online?

You don't tell us it is an input to the controller but that is a decent guess. If correct, then the controller is expecting a signal between 1 and 4.5V. > SO WHICH GOES TO WHICH? > There is nothing definitive about any of this: http://www.allaboutcircuits.com/vol_5/chpt_2/2.html I would guess the green is less likely to be supply or ground, and black and blue more likely.

A Hall Effect IC might do any number of things, and any voltage or resistance you read dependent on the internal circuitry - a mystery most likely. A Hall IC would require power and ground, and the signal would be a voltage output - not resistance. I Hall effect sensor could also be set up to produce a 4 to 20mA current. Or any number of other "things." Non-specific pronouns and nouns are so unhelpful. You have presented the throttle as being either a pot or not a pot. If it is a pot, then it will be very obvious. If it is not obvious, it is broken or some other device. > > I'll have the back wheel off the ground for testing. > > > > _______________________________________________ > UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub > http://lists.evdl.org/listinfo.cgi/ev-evdl.org > For EV drag racing discussion, please use NEDRA ( > http://groups.yahoo.com/group/NEDRA) > > -- To invent, you need a good imagination and a pile of junk.
