Guide to Hall Sensor Throttle operation, testing, and modification.

Hello. I have a problem with my bike. Following a total discharge of the lead acid battery (now replaced with a lithium), the accelerator no longer works. I measured the voltages and they are all correct (0.8V-4.3V). The engine runs at maximum if I press the button with the cables of the same throttle sheath (cruis controll?). I have no way of analyzing software controller settings. What may have happened?

Hi angelovola80,
And welcome to the forum! :-)

As your throttle voltages are good, my gut intuition would be a change in battery voltages or perhaps a damaged throttle cable. I recommend that you re-post this problem issue in the "troubleshooting" section seen here... https://electricbike.com/forum/forum...ouble-shooting
With full disclosure of your previous battery, and it's replacement. Model, type, voltages, homebuilt? Cell type? ECT... Details and wiring diagrams of your controller, throttle assembly, and other information of your system will be helpful and eliminate guesswork. The more the better!

See you over there!

Regards,
T.C.

I tried the beatiful schematics listed in https://electricbike.com/forum/forum...0588#post70588 and was not entirely happy with the results. Everything seemed like a compromize, I was either not getting the smoothing or losing top speed.

I gave up and used an Arduino to smooth my jumpy throttle, remove deadband, and add a knob-adjustable speed limit. If that helps anyone, here is the project:

Just found this incredible site, ,incredible community and writings, I’m in need of someone who I can pay to work out what issue my bike has? It’s a 2020 boom moto R3 10000w72v sat for 4 years, batteries good, everything lights up just nothing to rear wheel, I cannot find any shop here in vegas, only ebikes? I don’t care if you build bikes, work in your garage, I’d really like to have someone diagnose the issue? Controller? Hub? I’ve been trying myself but electric bikes aren’t something I’m good at, I’m in no rush, or they can cone here and test it out, I have a FarDriver controller, I have wiring diagrams, and bought a dongle that will be here in 2 weeks if you need that or have one yourself, I’d really appreciate someone letting me know anyone I can pay$ thanks, Ron

Hello, how can I discover the BME pin to install the hall sensor,?
I can't make it work.
