    Troubleshoot 2010 e-bikekit

    Just to wrap up this post in case someone is searching who has a similar problem: Turned out the solder connection between the Hall effect brake switch and the green (output) wire was broken and the green wire was intermittently touching the yellow (ground) soldered connection, thus inhibiting...

    Troubleshoot 2010 e-bikekit

    Well I'm back to working on this troubleshooting job - a friend who is a electrical tech is going to put an eye on it. He is asking for a schematic and I have already asked E-bikekit for one but they claim it is too old and don't have any info anymore. I bought the kit in 2010. So I am looking...

    Troubleshoot 2010 e-bikekit

    Very helpful amberwolf. I found ground (or common) for the brake switch is yellow, +4.2V power is red and signal is green. I disconnected (un-soldered) the green and was then, with power on and voltmeter between green and red, was able to verify that the hall effect brake switch is; a) indeed...

    Troubleshoot 2010 e-bikekit

    Amberwolf - that is a scary 790! Yes, my handlebar controller is a 790 (I made a typo before). I posted a photo of it a few back. That's good info that the hall effects might be sinking type. I checked as you described and got over 1K ohms so I think wiring is good. It doesn't seem that the...

    Troubleshoot 2010 e-bikekit

    I decided to re-solder the cutoff bake switch back onto the wires. The switch itself appears functional mechanically (there is a spring, then a small magnet, then a plastic plunger that moves the magnet into the switch body when the brake lever is released). I am guessing that the when the lever...

    Troubleshoot 2010 e-bikekit

    Thanks for inputs. I still don't have this e-bike motor turning. Regarding the throttle - I took off the cover (see photo) of the Wuxing and it looks like a solidstate 3-wire sensor with a magnetic strip on the adjacent moving throttle arc. I put a voltmeter on it and measured 4.26V across...

    Troubleshoot 2010 e-bikekit

    Thanks for your help. One of the brake levers has what looks like a good functioning switch. In the process of trying to get the motor working I have cut the wire to the other brake switch, leaving the 3 wires open circuit (the bike needs only one as it has a coaster brake). No difference. I am...

    Troubleshoot 2010 e-bikekit

    I have a 36V LiFePO4 front hub drive setup bought from E-BikeKit in 2010 that I am having a hard time troubleshooting. Battery is fully charged (reads 41V on digital meter!) and the handlebar controller turns on when power button is pressed and indicators light up normally, but wheel motor does...
