I don't see any mention of "reverse polarity" in the product descriptions. Works fine in my airplanes.

Mine works fine, but remember you have to separately plug it into the appropriate pins on your motherboard, if you did that and it still does not light, reverse the leads and try that. You would think that polarity does not matter but we've found out in this case it does. Also, don't pay the current price showing here of $84, I bought mine on sale from Amazon back in January for $49 including a $10 rebate, but for instance right now at New Egg this same case is on sale for $59 with rebate

As I recall, they are polarity specific. If they're in backwards, you won't get anything.

Center-tip-negative polarity is not the norm, easier to buy one here. You'll see one in the "customers...also bought" links--e.g. Planet Waves 9V Power Adapter, which has the polarity you need. Just make sure any adapter you use is "center tip negative".

Thanks, i'll check for the switch on the back tonight. i'm sure the polarity is correct, red to lead (+) and black to ground (-) right?

I just received this wireless card today, (September 2014), and I can confirm that the usb polarity was correctly labeled on the device I received. I actually tried installing it backwards first due to recommendations here on amazon, but it would only work for me when I installed it in in the orientation suggested in the manual. So I would recommend trying it the manufacturer suggested way first; that would have saved me time.

You should just need to change the two wires, it sounds like wired backwards. On my set, the wire colors were different between the right and left housings, the ground wire is the same color on both housings.

I'm gonna say it's defective - I am aware of no way to manually change the direction, so I assume it must be wired in reverse.

It's the polarity which is reversed and don't ask me to explain that. I finally gave up and started using batteries. It works fine and the batteries last a pretty long time. Good luck.

I am guessing "NO" since I originally had the wiring polarity hooked up backwards and didn't have a reading.

No, I had the same problem. It means that your hot and neutral are reversed. Just switch the wires until it only comes on when it is turned on.

Look on the heel. There is a symbol for polarity and input voltage, ac or dc. Take the unit to a store like radio shack and have the clerk match you up. It is NOT proprietary. Test your charger with a little meter. Buy one when you are at RS.

Do you mean that the connectors for (+) and (-) terminals of 9V battery have collapsed? Try using a long-nose piler to gently bend the connector back into shape. If that doesn't work, go to Radio Shack and get a replacement connector and solder it to the charger. Just make sure you get the polarity correct.

try taking it apart, the two big screws in the front, and move the wire so it comes out the other side (The Philips is designed to do this)...it sounds like its running backwards...let me know if this works...k

Batteries are in mounting base . Remove cover, remove old batteries, replace with fresh batteries observing polarity

Make sure you dont have the cable connected the wrong way. It can be connected backwards. Switch the cable ends.

I just got mine too but I did not do anything to it...just switch it on and it works fine...I think u should contact the company to exchange a new one for you.
