Re: Can't get KT LCD5 headlight function to work

I've just gone through some old posts so didn't notice yours until now. I discovered that the motor controller itself has a connector inside, which has 5v on it when the light is switched on. If you're OK with some electronics you could wire up a FET transistor or similar which could switch the ligh...

Re: KT36SVPR-LCD Controller

Magnus - I had a similar problem with the KT pedal sensor. This sensor has a centre disk which is enclosed within a case which has the hall sensor in it and the wire coming out of this outer case. It turned out that the bottom bracket of the bicycle wasn't perfectly centred. This meant that as the c...

Re: Kunteng/BMSBattery/KT controllers - light output microcontroller pin and hardware differences?

To follow up for anyone still interested: I managed to get lights wired up, and switched on and off from the LCD3, so I'm pleased. Looking at the light module schematic posted elsewhere in this forum, pin 4 appears to be used as a sense wire input to the microcontroller; without it connected the lig...

Re: Kunteng/BMSBattery/KT controllers - light output microcontroller pin and hardware differences?

OK, so to answer my own question again in case it is useful to others in the future: The KTE-6S3 controller *does* have a pin to control light, which seems to work with the stock firmware. This pin is available on the 4pin connector marked "DDB" which is near the green phase wire connection. Pin1 is...

Re: Kunteng/BMSBattery/KT controllers - light output microcontroller pin and hardware differences?

Thanks for the links. I think there are at least two versions of the hardware - one with the light output, and one without. From the link you posted the version with light is here: https://i.imgur.com/BzNZp8z.jpg - model KTE-6S5 but the board I have is more like the one here: https://opensourceebike...

Re: Kunteng/BMSBattery/KT controllers - light output microcontroller pin and hardware differences?

Following up from your hint about the open source code, I managed to get it to compile OK, so that's a start. I decided to look through the code to see where I would add a light control, and there was a a commit on 25th May 2019 to all light control already, so it looks already to have been done! It...

Re: Kunteng/BMSBattery/KT controllers - light output microcontroller pin and hardware differences?

Thanks for your reply. I had already thought of using the open source firmware to do this, so glad you agree. I have an STLink programmer already- I just need to take time first to read through the long thread which is full of information! I have other ideas for additions - having a solar trailer, i...

Kunteng/BMSBattery/KT controllers - light output microcontroller pin and hardware differences?

Hello all, I can't find this information answered on the forum but there may be knowledge out there... I have two questions regarding a controller model KT24/36SVPR-HRD01: - Is there a microcontroller pin on the controller that switches state when the LCD backlight comes on and off? I'd like to use ...

Re: KT KT24/36SVPR - Intermittent behaviour/Hall sensor learning

So the bike now appears to work OK. The following got the KT controller to work with the Transzx motor and pedal sensor: - The pedal sensor connected as follows: sensor red wire to controller PAS connector brown wire (+5v). sensor black wire to controller black wire (ground). sensor yellow wire to c...

Re: KT KT24/36SVPR - Intermittent behaviour/Hall sensor learning

Hello, So I've made progress. After writing the message above the "intermittent" nature stuck with me so did some more testing with the oscilloscope. (For anyone looking at this in the future, the white cable on this motor is a 1 pulse per revolution wheel sensor, and the blue,green,yellow wires are...

KT KT24/36SVPR - Intermittent behaviour/Hall sensor learning

Hello all, I've been playing around with a EBCO Pulse 2 Electric bike which was donated as it had a faulty battery. Battery BMS board replaced and it now has power. TLDR: I've fitted a new KT controller but it isn't quite working with the motor not turning, or needing to be pushed backwards to make ...
