What are the black and white wires from the LED Display for? What should I connect them to?

I bought a new LED Display and a new controller. When I connected my new LED Display with my NEW controller, the LED did not power up. See attached photos. To narrow down the problem, I did the following:- 1) I connected my NEW LED Display with my OLD controller, it didn’t powered up too, 2)...

I checked the Hell wires, they are good, no loose connections. Even when I disconnect the hall wires from the motor to the controller, the motor still works but the problem of motor cutting off and then cutting in still exists. Should I change the controller and see how? PS : I saw on the...

Besides the 3 phase wires connected from the controller to the motor, there is a bundle of 5 wires, the Hall sensor wires, yes, they are connected. Was it silent prior to a year ago? Not so noticeable prior to 1 year ago. If your display does show current or power, try lifting the back wheel...

Yes, I'll check it and probably get a new controller. You don't suspect motor problem?

No, the controller doesn't get warm in almost all riding conditions. The power cut is a sudden one, no slowing down or whatsoever, in any case the power will gradually reduce to zero during when the bicycle reaches about 35 kmh, this is due to the speed limiter, I have no issue with that.

Now you ask me about the motor, I realise, yes, the motor does give out whizzing sound when it is under load, not particularly loud but noticeable if the road traffic is light, I can hear it. This sound came only in the past 1 year, or thereabout. Could it be motor going to fail? In any case...

My controller is brainpower, 36V, 250/350W, maximum current is 13A. The combined mass of bicycle and rider is 117 kg. Terrain wise is mainly flat, city riding, with slopes less than 5 degree gradient. Undersized it may seem, but I have been using this controller for over 3 years, it didn't...

Alright, let me rephrase it. Before I ride, I switch on the battery, and the display turn on (with lights on the display, power indicator etc). As a starts to pedal, the power assist comes in (I only have PAS, no throttle), but after between 5 to 8 secs, the power cut off (it loses power, the...

Hi E-HP, thank you for your reply. I don't quite get what you mean by "cycling the battery". What I encountered is this. When I start pedalling, the battery will cut in, but after about 5 sec (sometime longer, sometime shorter but it never go beyond 10 sec), the motor will cut off. Then after...

Hi, finally I bought a brand new battery, 36V, 13Ah, Panasonic cells. However, the same problem exists. The motor will cut off after 5 to 10 sec after cut in, without any apparent reasons. I suspect it is due to too much current being drawn from the battery but I'm not really sure, it cuts off...

Thanks for the replies. My current LCD was caught in a heavy rain, now it is functioning intermittently, that's why I want to replace it with a cheaper one. Looks like I have to get back the same LCD. Just wonder what will happen if my current model is phased out in future.

Hi, currently I'm using this LCD as shown in photo 1. I intend to change it to S800 LCD as shown in photo 2. Both have 5 wires of various colours, but they are not connected in the same sequence. I wonder if they are compatible, in other words, can I replace my current LCD with S800 LCD? The...

Hi E-HP, Just to close the case and let everyone knows, I followed what you said plus reading the instructions. I connected the ignition wire from the ignition cum voltmeter switch to the thin red wire of the controller. I left the purple wire from the controller free, that's, I didn't...

I am not confident to open up the battery with the warning sign on the battery. I guess I'll just bear with it until I get the most mileage out of the life of the battery and then replace the whole battery. Thanks again for the advice.
