A magic pie 3 that wont start, updated with photos

[greverif]

Hi!

I recently bought a Magic Pie III and hooked it up with 4 6s lipos with 5000mAh each which basically gives 44,4v 10A. I have tripplechecked the batterypack and it is connected right.

When I connect the battery pack the battery indicator on the throttle lights upp to "full" but when I push the throttle nothing happens. I havent installed it on the bike yet but I guess the engine should start anyway. I have connected it to a pc and confirmed that 48v its choosen. Does anyone know any particular things I should look for or that I have missed? I am a rookie at this. Or is it the famous controller thats broken? I have read that it is a problem with the internal controllers quality.

I have tried theese things with zero result:

Updated! I opened the controller, the red and blac cable is loose. I guess that is my problem? Now I need to now where they should sit, Do anyone know if the red one is under the blue or yelow cable? I cant find a picture of this anywhere.

Contact Golden Motor, or post on the GM forum is probably your best bet.

You could always take out the existing contact from the plastic shroud, and see if there is any of the insulation on the contact. That would give you a heads up.

That's the hall sensor connector.
Looks like this?

 

[greverif]

Yes!
Thank you very much!

Could this be the problem?

 

[MAGICPIE3FOCUSPOWER]

yes I think so!
When I had the Magic Pie it doesn't work when one of the hall sensors was broken.

Just connect it and you will know :wink:

I have to buy à New connection like the one on the picture below. Its just like à pci-express connection but smaller. Does anyone know whats the exact name/brand/product number on this connection?

I did find the connection but it still didnt help. I also opened the wheel but all contacts seem fine. I guess the problem is in the throttle or the controller.

This happens when i put in the battery and start uses the throttle.

Here is a photo of the settings I use. Also, the throttle I use is a 48 v throttle. But using 44,4 v battery package should work with 48v, right? Edit: measured My battery pack, it is on 50.1v so that should work.

Maybe irrelevant as I've never changed my factory settings, but acceleration set to 0 looks odd

Dude!

Although this may not resolve your problem, You should have the motor in dropouts (IE a bike Frame). with the axle at least partially secured before you spin it up to test it.

If the motor did actually spin while you have the wheel/axle unsupported, the axle will spin, not the wheel and that is likely to end in tears.


It'd be awesome if the motor isn't spinning up BECAUSE it somehow senses that the axle is free to turn.... I doubt this is the case tho :{

I know guys, I just didnt feel i needed to put the wheel on the bike to show you since i knew it wouldnt rotate. I have confirmed the problem was the controller and bmsbattery have sent me a New one.

Schweeeet ... Good outcome, and that makes sense greverif, seein' as you already knew it wouldn't spin up
