Unhappy How do you test a throttle?

recently got my first electric bike. Did not cost a lot being a no runner.
So have been putting it back into running order... However
I've checked everything else out battery's, brakes, motor etc.. but still not up and running.
Knowing the motor is fine means that the problem is either the controller or the throttle and before I go out and buy a new controller I like to know if there is a way I can test the throttle..

I have tried testing it as you would test a potentiometer with my meter.. not much help got no reads at all..

Can anybody help, just need to get over this step and I can get my bike out on the road..


Many thanks

If you got no reading, then it sounds like a bad throttle control.

That is correct if the hand throttle is a potentiometer.. but I'm not sure it is, hence the question
When testing it as a potentiometer I get a reading across the unit but not centre reading. I would have expected to get a reading that varies as you twist the throttle.

I'm 99% sure it's a potentiometer. Hopefully somebody can confirm.

A lot of the throttles these days are not potentiometers, so the testing is different. I find the website of ebikes.ca has a lot of usefull information. Check out: http://www.ebikes.ca/troubleshooting...tleTesting.pdf I hope you find out what the trouble is.
