    I have to remove my motor's main power and sensor cable just to replace the axle bearing on that side due to the too big connector on the end of that cable. Watching your work really helps me see what's required to get that done. Great video as always!

    Leaving stubs of the old wires is a great way to get the colour coding right when fitting a new cable. Alternatively take a photo with your phone, and refer to the photo when reassembling.
    I have found it helpful to solder the phase wires of the new cable to a single wire, pass the single wire through the axle then use it to pull the new cable through... it helps to get the cable round the tight bend where it exits the axle.
    Thanks for the video..

    Good video thank you. I want to upgrade to an L1019 and add a thermistor, do you think an L1019 would fit through the axle hole? I believe the overall diameter should be lager due to the larger phase wires.

    Could you reccomend a display / controller combo for a 750w rear bafang 48v please?
    I got on ebay:
    Ebike 36V/48V 750W/1000W 26A/30A 3 Mode Sine Wave Controller + S866 Display Set
    but when I connect up as soon as switch the battery on the back wheel spins for half a second then stops, when I switch the display on there is no life from the motor either PAS or throttle.
    Controller fault or my wiring? I got the 30amp controller, is it too powerful for the 750?

    • @EbikeRepairs
      @EbikeRepairs  Před měsícem

      That's for the donation! I'd recommend the KT 20a or 25a controller, the KT LCD 8 colour screen.

    • @EbikeRepairs
      @EbikeRepairs  Před měsícem +1

      Sounds like wiring is wrong, disconnect pas and throttle and see if it still moves, then try the walk assist holding down button on display.
      Make sure the self learn wires are not plugged in (white + white single wires or green single wires that go back into controller)
      Also the 30a is too high for controller, 50v* 20 amps is already 1000 watts peak so 30amps will get melty

    • @utubeape
      @utubeape Před měsícem

      @@EbikeRepairs Thanks, I got a new controller, the 26A version. It works, it operates the motor via the throttle but no PAS. I bought a new PAS which is the pedal crank type, still nothing. The wires were different colours so I cut off the plug male and femal and wired every combination, but still nothing. Its not the end of the world to have the bike throttle only but not good especially if stopped (though the throttle lever is small and discrete.

    No I think you just need a gun cleaning wire brush and clean it out from both ends I think they purposely put silicone in with the wire at the same time

    • @kaygerry
      @kaygerry Před 2 měsíci

      They did, it's to prevent tension on the other end pulling the solder joints off the board with the wires. Silicone should probably be added back into the end to prevent it being ripped out by accident.

    Hi mate, I have a 750 bafang and a freewheel that is very much not working well 😂 as the motor plug is too big I can’t use a freewheel tool easily, would doing this make it easier to get my freewheel off while having the cover and freewheel as my only other options are cutting freewheel tools until I can make it work or splicing the wire 😂 any help would be appreciated mqte

  • @MrTimmmers
    @MrTimmmers Před 8 měsíci +2

    I found that since you're cutting the new cable end off you may as well get a much longer on, it's a difference of 1 or 2 quid, then you can use the cable left at the other end to test your controller without dismantling anything. I haven't done much soldering for years so I used a bit of the ample spare to practice on. I found it easier to loosen the screws while on the bike and nice and held still.

    A 07E error code is usually an error direction which would be a hall error and the solution is to check the connection. It can be anything from the Hall sensor or even a pinched wire. If I am correct the hall sensor would be a 41F.
