Hi!

The wires on the loudspeaker (beeper) of my old AT box broke.

I need to if pin 1 (red) of connector is positive or negative, to solder the wires again.

Maybe @Gammitin can help me?

I don't really know your device, but: Usually red indicates positive and black ground.
If its only one small speaker, polarity does not really matter.

@microblogc Hi. Do you mean the old PC speakers that only beep? It doesn't matter which way you connect them. The only thing that would happen is that the diaphragm would move "the wrong way," but it would still beep. It might be too quiet then, though; in that case, just reverse the connections.

@microblogc @Gammitin convention is red = +ve, black = gnd

But it doesn’t matter if it’s just wires going to a speaker (unless there’s more than one speaker, in which case they all just need to match so they’re not out of phase with each other)
