Hi guys I've got a new sur ron style throttle for my ebike what do you guys know what is the Earth signal and 5 volt positive

Fortunately you can’t do any damage to the hall sensor in the throttle or the controller if you get the wiring wrong. But your bike will take off at high speed if you put 5v onto the signal wire to the controller.

 

I have seen surrons cause absolute mayhem when their throttles go wrong.

 

My guess is:

 

Blue +5v

Yellow signal

Black 0v

 

Surron wiring is

 

Red/White +5v

Black/White 0v

Green/White Signal

Thanks mate only got one as I've got a stealth bomber bike a youtuber is useing one on a stealth bomber as iam doing it in my kitchen don't wont it to spin up fast and mess my lino up the other half will not be happy my wire is blue brown black

Yeah, a Stealth can cause a lot of damage in a kitchen on ghost throttle.

 

For some peculiar reason, the Chinese seem very partial about using blue for +5v. But then again some do and some don’t. I think it depends upon what kind of a mood they are in when they are wiring on any particular day.

I might wait for a nice day and do it in the garden
