I broke the connector. I watched videos on youtube. They exposed the copper and soldered again. How do I know if it is correct? do I have to do it another way? I am interested in knowing how to see that the voltage will arrive and what is the way to solder the connector If anyone can help me thanks
First solder the tracks where you've been scratching, they should be nice and shiny, this is called tinning.(Look on YouTube for soldering). Do the same with the plug. then solder the two together.
How did you manage to break it?
Good luck............
