emax 110s blue smoke

Does anyone know what caused this !!!!!

It was quite strait faward to fix. first push out the female sockets using pin,s

Then after that new wires.
jobs a gooden.

And allso found a tacky conecter that held the charge leed on which fell apart in my hand .
and here is the fix (The way it should be originally and y not use just 2 wires)
The Emax is a nice scooter carnt they spend a bit more time putting it together.
