I’m from the united states by the way

Can you send me link of what the BC looks like?

I mean what would I replace

Would I replace the wire or the box

No unfortunately I figured asking you guys could help me

It’s demo scooter if I forgot to mention

I got the scooter from someone and I have no idea how old it is and I will have to wait until I get home to tell what battery it is. If it is the charger would there be another to turn it on?

And also there was burning smell when I plugged it in
