Ninebot E+ charge input short circuit

Hi everyone,


I found the loader wheel beeper gently every 2 or 3s. Once disconnected from the wheel he stopped doing it. I inspected the 4-pin connector, it smelled burnt and was a bit blackened.

The ohmeter indicated a short circuit in the two pins used by the wheel. I eliminated the fault, reconnected everything,

big spark ... Verification done is the input of the connector which is also in short circuit and which, under 60 V, the charger absorbs a current which damages the connector. Yet the wheel is working properly.

 

What to do ?
 

Thank you for any help.
