Inputs and Tips

[markgarrigan]

So what do these mean?  The power supply input on devices.  The actual input is on the top and the polarity i'm guessing is under it.  Which is the cable end?  And what charge would the "TIP" of that cable have?

       --------                       --------
       |  o  |                       |  o  |
       --------                       --------

     - ---C--- +                  + ---C--- -

Thanks!

the one on the left is tip positive, the right is sleve positive. On most plugs (except for the ones shaped like headphone plugs) the tip is really the center.

Be careful with sleve positive tips, as contact with grounded metal surfaces will cause sparks.

thanks...

i assume this holds true for adaptaplugs...which is what i'm talking about......

if i have the one on the left....my adaptaplug should be installed to the adaptaplug female cable with the positive(plug) and "TIP"(cable) lined up....correct?

[bhtoque]

yes.

With adaptaplugs the tip should be sticking out over the positive mark on the cable.

I have never trusted the adaptaplug graphics, You guess wrong and BOOOOOOOOOOOOM.  Get a cheap multi meter, it will be the best ~$10 you've ever spent.  I use mine all the time.

Very good point. Better safe than sorry.

On the same note, put fuses into your battery cables. I can't remember exactly, but I think Doug Oade told me 2x the amp draw of the device for the fuse.

lets say your adaptaplugs are correct....do you just connect them as the diagram on your device shows?...you don't make a cable opposite of what the diagram shows right?
