I'm such a noob

[Cern]

Very stupid question. On a pair of wires that are both black, is the wire with the white stripe on it the positive or negative?

I was on the phone with my friend (who went to college for this kind of thing) for an hour and he couldn't give me a straight answer.

This is going to be soldered onto my rechargeable battery pack, and I'm using an "adaptaplug" from Radio Shack.

What's it on?

If it has power to it an easy way to find out is attach an LED to it that has the +&- labled. LEDs can only be hooked up one way, so if it lights that will tell you what wire is what.

If these are just wires that you are using to extend the wires on the Bat. pack, it's your prefrence. I'd GUESS that the wire with the white strip is +. But that is only a GUESS!


If I knew what it was attached to I might think of another way to test it using common saber building tools.

There was a time when you could count on the white strip being positive but now it is a toss up the only way to tell for sure is with a voltmeter

Do you have a multimeter? If not you can pick one up at Sears, Home Depot, Lowes, Radio Shack etc. If it was your connections then you could make it however you want but there is no way for any of us to give you anything more then a best guess from experience. Over 10 years of electronic field work and I can tell you for sure that I would through a meter to it unless the transformer or whatever you have is clearly marked. I doubt that it is not a polarity sensitive circuit although it may be possible.
Cern, this isn't a stupid question, just a real tough one to answer with out having pics or a tech spec sheet.

yea i think hes saying that he's using spare wires or something... it doesnt matter which is which as long as you remember. They aren't polarized, so it wont affect anything.

Ok, here is what I have soldered to my batteries:

and it plugs into this on the ac adapter:

So i just want to make sure i dont have the wires soldered to the wrong parts of the Driver board. Unless of course that wont hurt anything.
