LCD is always ON, and it always shows the correct speed.

My TSDZ2 is 4 years old already. Maybe it's time for some maintenance:) Recently, it started bugging me with inconsistent power output. It starts and works correctly for the first 5 minutes (or less), and then randomly cuts the power. Especially when you go uphill, it's practically not...

A year later: the engine was dismounted, and an old plastic blue gear was replaced. It was convenient to update the control unit at once (just €45, https://www.aliexpress.com/item/1005004586875464.html). And then the magic happened: I got exactly the same issue - speed is shown/changes only...

No, here's the broader discussion, https://www.pedelecs.co.uk/forum/threads/tsdz2-speed-sensor-works-partly.41774/#post-624296

In my case the brake sensor (the circuit from one to another contact of brake sensor connection) is connected when brake is not pressed and disconnected when brake is pressed. Obviously, the only purpose of the brake sensor is to disable engine when brake is pressed. Brake pressed <=> circuit...

Yes, I used the left-most and the right-most. But also tried center and left - this case the signal from brakes does not go, the speed sensor works, the engine does not work.

The issue might be related to brakes with sensors. The behavior is quite strange. If I disconnect any one of the brakes (or both brakes), the speed sensor starts working. But at the same time, the engine itself stops working - no power assist. So I can either use the engine or have the correct...

I already wrote about it here, https://www.pedelecs.co.uk/forum/threads/tsdz2-250w-vlcd5-speed-sensor-strange-behavior.41280/#post-618132, and the problem still persists. Maybe, if I write it in another words, I find somebody with the similar issue. The issue is my VLCD5 shows the current speed...

Is it possible to factory reset the kit? I already reset ODO by pressing +- for 10 seconds.

The basic kit (TSDZ2 + VLCD5 + brakes with sensors) was installed a week ago, everything was working fine. Then the head/tail light set has arrived (like https://www.aliexpress.com/item/32948574121.html). It has another speed sensor with splitter to provide power for lights. The kit was...

Finally it started working. I guess the initial issue was battery overcharge (41.5 instead of 36). After discharging it was tested at home through walk assist function, but the last does not work for some reason. Nevertheless, today before sending to service tested it one more time outside - and...

What does it mean? How to set LCD to 36v? It's VLCD5.

Discharged to 39.4v, no change.

Discharged to 40v using a suitable chosen power resistor (kettle). Still does not work.. But I have a nice hot tee now.

The battery is 36v 10.4 Ah, currently it gives 41.8v. hm.. How to discharge it?
