Help! Folding electric bike error 10

[Jamienorman1]

Hi,

I'm not sure if I'm posting in the right place but I'm in desperate need of some help with an error I'm receiving on my new ebike.
Basically I bought this folding bike about a month ago and all was great until a few weeks ago I started getting error 10 on the screen and have no power or lights working.
It will sometimes turn on and function fine.
I know it's not the LCD twist throttle as the lights are wired separately so I think it may be the control box which I cannot find a replacement anywhere on the web.
If anyone could help with this issue id be forever in your debt as it's really frustrating.

Thanks a lot

It would help if you let us know what you have. There must be many hundreds of different folding electric bikes.

My apologies.
I purchased it off Amazon and is called magicelec y1 by freego.
Also know as dohiker and guangya.
Is 36v 350w with key ignition.
I'm so sorry if I don't make much sense as I'm very new to ebikes.
I've added some pictures I'm sorry if there not of much help.

I don't recognise that LCD. I don't think I've seen it before. Can you look at the back to see if it has any writing on it or codes that might give us a clue? Also, zoom out and take a photo that shows the whole thing.

How did the problem start? What were the circumstances?

So basically I was out for a ride, got home then turned it off.
I turned it on the next day to go to work and the error just appeared for no reason at all.
It was fine for the first 2 weeks or so.
There are 8 settings in the menu which I have not altered at all i.e. voltage is set to 36 and wheel size is set to 14 which is correct.
If I turn the ignition off and on a number of times it does eventually get going.
I've also checked all wires for loose connections but all seem fine.
I've attached some pics of the LCD.

Error 10 means that the LCD isn't communicating with the controller for whatever reason. Have you been riding in the rain?

I haven't ridden in the rain as I'm not sure how waterproof it is.
Do you think it will be easy enough to replace the LCD throttle with a different one or would it need to be the same?
I was thinking if I did need to replace it would it be possible to use one with a push button rather than a key?
Would you say the controller box is ok or could it so be an issue?
My apologies for so many questions.

You have to find the reason for no communication first. Many things can cause it. You need a meter. Measure the voltage between the red and black wires on the throttle, PAS or hall sensor wires. Tell us what you get.

Ok I will grab a meter tomorrow and try the test and let you know the readings.

 

[Jamienorman1]

So I've done a few tests I think I done it right.
It's showing throttle 1.14v Pas 6.25v and hall 3.79v I'm not 100 percent as these wires are crazy confusing.

 

[vfr400]

1.2v is the voltage for the throttle signal wire. The red wire on the throttle should be 5v. can you check again?

 

[Jamienorman1]

Its showing 1.14

 

[vfr400]

Its showing 1.14

you have something connected incorrectly then. Disconnect it , then measure the votage on the red wire.

 

[Jamienorman1]

I've just about given up on this and ordered a complete new throttle lcd.
I appreciate your help but other than replacing the LCD I'm completely lost.
The only problem with the new one is that it does not have the blue wire in the middle of the red and black and is a push button rather than a key.
Do you think it may still work ok?

 

[vfr400]

All of them will work if you wire them correctly. Without identifying the cause of your problem, it's not possible to predict the outcome of your new purchase. The cause could be in your controller or wiring.

An electrical item can't kill itself in the middle of the night when not being used. There would always be a logical cause.

 

[Jamienorman1]

Ill try the new one when it arrives and let you know how I get on.
My guess would be the lcd has gone as the voltage is so low on the red cable.

 

[Jamienorman1]

So I've tried the new throttle and no luck.
The bike is in bits and will soon be going to the dump.
I'll be investing in a reputable bike as I have learned my lesson about cheap Chinese rip offs with there horrendous wiring
Thank you for your help with this.

If the 5v line is down in the controller then it needs a new controller or better still replace the whole electrics kit for about £70 to a better system.
But first the voltage fault needs confirming, measuring the voltage is pretty easy via the lcd ,throttle or PAS ( with block connectors) to confirm that 5v is present and correct.
Guessing at what might have failed and buying parts willy nilly is never the solution and a waste of money.
Check the meter accuracy first by by testing on a known good source like a new 9v battery.

 

[Jamienorman1]

Ok so i think im keen to try a complete new electrics kit.
Can you recommend anything that would be suitable for this bike as it has lights, horn and brake lights all built in.
im not bothered about the horn or the 3 speed settings i just want the thing to run and be able to see how much battery is left.

Test the controller 5v line correctly first to rule it out.
