I took apart a lighter cell phone charger. I plan on splicing it right into the lighter. The main wire leading into the circuit board has red black and yellow leads. I'm guessing red is + and black is - but what about the yellow, is it necessary? Anyone have a clue based on the photos:




Thanks!

so your planning on having a permanent cellphone charger in your car?...

well it looks to me it's a ground wire for your cellphone side. look at the backside and see if it's connected to anything.

its actually a PDA charger which also splits into a connection for my GPS antenna but to make things simple I called it a cell phone charger. Right next to the yellow wire connection are the letters "FR" printed on the circuit board. That's about as much as I've got:



Reverse side.

Looks to me it's part of the positive side. See the picture, the + and -. The yellow one is on the metal board along with the black wire. Looking at your first picture, it looks like there's 2 wires comming in from positive side as well. A black one and a red one, and then a black wire for negative. I'm guessing your PDA or whatever it is, has 2 places where positive touches.

So are you planning to hard wire it in while keeping the circuit board? I wouldn't reccomend doing otherwise, as that PCB probably has voltage regulators and such. If you do splice it in, just cut off the red and black wires before they get to what's left of the old lighter plug, and connect red to the center wire of the lighter, and black to the edge.

On another note, 500th post!!

if i am not mistaken, you could just cut the red and black wire (where you insert it in the cig lighter) Its in the first pic all the way to the right just cut the red and black wire and connect it st8 to the power source.

do what i did i hard wired a second cigarette lighter or plug behind the stereo, ashtray and pluged the car charger into that than ran wires... much easier and dont have to worry about anything else

Thats what I did, and it works great, be sure to use a fuse, just in case. I used an inline fuse holder.
