Thanks for your help, I will get a new display and try, sorry I don’t know much about these e-bikes, but I am learning all the time, enjoy your week and thanks again

Don't forget that there are two different connectors.

Hello again managed to source a new display, but only stays on for about 30 seconds, do I need any special instructions for setting up? Or is there another issue, the motor kicks in when I turn the pedal, any help will be appreciated, regards John

Do you know which version you have, CAN or UART?

 

the next thing to figure out is whether it's the battery that shuts it off or whether it shutting itself off. You need to put a voltmeter on the battery to see what happens to the voltage when the LCD shuts down. If it holds steady, it's the LCD. If it collapses, it's the battery.

do not understand CAN or UART?

I have to unplug it to get the screen back on, then it shows all the symbols then goes to just the mph/img screen, I think I need some code, will try the battery voltage, but it does come back on every time I re plug it in? Cheers John

CAN and UART are two different communication protocols. The controller needs the same one as the LCD, like people talking in different languages and they can't understand each other.

Thanks should the display suppliers know what their item is, either CAN or UART, or can I easily find out this information, kind regards John.

It depends on the seller. Some mention it in the listing. Some haven't a clue what they're selling, and everything in between.

Just found that the new display is showing an error code 30H which means a communication error, obviously the wrong display for the bike, any ideas I will post pictures showing the old display and the new one, maybe just give up and scrap the bike, here are the pictures

Not necessarily; however communication error is difficult to track doen because of it can have many causes. Things to check are the main cable from the controller damaged or squished by cable-ties. Check that you have 5v on any connector that you can get to that should have it: motor halls, throttle, PAS or brake. Your symptoms keep changing, so it must be an intermittent connection or short somewhere.

Confused as someone else mentioned that it could be be how it communicates CAN or UART, so could this display be compatible? Thanks for your time with this

It might be, but you can't test that, so eliminate everything else first. You could also look at the battery connector. If it only has 2 wires, it's unlikely that you have CAN.

Thanks again checked all cables and connections and all seem to be okay, couldn’t find a connection with 5 volts on, should I be looking for a UART display? Thanks again for your help

Did you check the number of wires on the battery connector?

Yes there are only 2 wires?

In that case, you probably need the Uart one, but that might be what you already have. Can you check with the supplier?

Sorry to bother you again, but just put the old display back on the bike and it has a 26H error code on it, which seems to say that it is something wrong with the Torque sensor speed failure, would this affect the e-bike from working at all and would it be an easy fix?

 

Thanks for your help with this matter John.

Does it have a torque sensor? I thought it didn't. Spec. says Sensor: speed, whatever that means.

 

I think that there are too many uncertainties with what you have. It might be better to get a complete controller kit with LCD, throttle, etc. Your battery has two wires and your motor has the standard connector, so any controller within reason should work.
