[RV100000]

I have a four wire fan however there is no green wire. Can anyone tell me what the orange wire is?

What ???? this makes absolutly no sense, are you talking about a computer 4 pin fan, what sort of battery ? they way you sounded this makes it sound like you should be asking this question in a car forum, pictures say a 1000 words.

If you're doing what I think you're doing, you need to google whatever fan you have, and find out what the wiring scheme is for it. That should tell you what the + and - cables are, and then you can connect them to the corresponding battery terminals.

Usually positive is marked by a red wire, and ground by a black wire. Green is not a common color for wires.

1. Battery
2. Fan, with 4 wires

Strip a small section of insulation off all 4 wires.
Try all possible combinations of the 4 wires to the + and - terminals of the battery.
When it spins, you've found the correct ones.
If it spins the wrong way, switch them around.

If it never spins, either the fan is broken or the battery is too weak.

It's a Toshiba portege fan.

It's a Toshiba portege fan.

Yellow is your 12v live, red is the 5v live, black is ground and Blue/Green is signal.

Put yellow on positive terminal and black on negative, the fan will run at 12v
Put Yellow on positive terminal and red on negative, fan will run quieter at 7v
Put Red on positive terminal and black on negative, fan will run at 5v.

Put Red on positive terminal and black on negative, fan will run at 5v.

Unfortunately I have tried all of those and it has failed to work
The fan does work and so do the batteries

The wire isn't yellow it is orange and on the manufacturers website it is orange too

Try red and yellow together on positive terminal and black on negative, thats a 17v starting volatge, otherwise im at a loss.

Looked yellow when I googled it.
Ahh, have you tried just red and black ?

17v starting voltage is quiet a lot for a fan, most fans only need between 3v and 5v to start.
