Help with servo tester to hall throttle?

[Evan177]

I was following a guide on ES on how to use a servo tester to hookup a hall throttle up to my esc. (can't find it now but this picture is the same thing: https://s59.photobucket.com/user/Ticket2fly/media/escthrottle.jpg.html)
My throttle does not have a black wire? Only white, brown, red, green, yellow, blue, and grey.
Any advice would be appreciated. If there is an easier way to do it with a Vesc 4.12? I can do that as well. Thanks!

In short, get a Cycle Analyst V3. It will do that, and be the ride computer and power meter you need.

To be absolutely certain, open up your throttle and match the wire colors with the hall sensor pin-out.

Gotcha will post update later today.

From your picture(s) it appears that the Blue wire would be your throttle ground. (middle terminal)
Verify by wiring…

Red to 5vdc+
Blue to 0vdc (ground)
Checking that White is variable vdc output... ~1vdc to ~4vdc depending on throttle position.

Thank you for your help so far! Wired according to the diagram, the servo tester has power and the vesc is reading it. The throttle is unresponsive.

Question: Isn't the VESC programmable for it's input throttle voltage range and type? Meaning, can't it operate with a regular analog voltage range input, and not require a PWM pulse train instead?

If so, you don't need a servo tester to convert a hall throttle's output to PWM for it, and can directly connect it and just change the VESC settings to match.


Or is this just with newer versions, and not the 4.x?
