Arcing to the point where there is now a large hole where the pin should be.
IMO The current PCB is FUBAR.
I hope I haven't got the boards mixed up, only going on what the current board number says. This board has this variable resistor thingy which if I get wrong setting could in fact...
Hello,
My current board has just started arcing across one of the top connectors. (I assumed from a dry joint and not from another fault). I have ordered a replacement board.
However, on this PCB model type , there is a variable resistor in the bottom centre.
What does this resistor...
