Powering fans by splicing power chord?

hello,
my air hockey table died from a damaged power supply, but i was wondering if it was possible to splice a power chord to the 2 7 inch fans under the table as an alternate power source.

the fans are connected to the main power source (the one that died) by a only a green and copper colored wire.

is this possible and if not what could I do to get the fans running again?

Thanks!!

What voltage are the fans? Are they AC or DC?

What you are describing sounds like ground wires. Ground wires are never used to power anything.

Can you post a picture of your power supply, fans, etc.? I'm going to guess the fans require a specific voltage.

pics

picture number 1 is from the main power supply box (forgive me if im using all the wrong terminology!) that has two cords coming out of it each one connecting to a fan. on the box it say "120 volts AC, 50Hz, 1.06A.

if you open the box you see (pic 2) the main power supply being split in two and each part being connected to either two blue wires or two brown wires (i mistakenly said they were green and copper earlier). From there a brown wire and blue wire are earch paired and sent to connect to each fan (pic 3)

As long as I can get these fans moving again I will be back in business!

Thanks for any and all help!

Is picture number two picture number one open? If so that is not a power supply it is a junction box. But you wrote:

So is there or isn't there a power supply. We need to know so we can answer your question.

Also we need to know is there a nameplate on the fans? What does it say?

There is no power supply visible in your pictures. There is a pair of splices visible, which separate the incoming power to go to two loads - the two fans.

The information on the cover of the box states "120VOLTS AC, 50Hz, 1.06A" as the power requirements. I would guess at a mismatch between the cycles stated in the requirements and the cycles in the supply (50Hz v. 60Hz), except that the table and its fans have apparently been working OK since December of 2003.

I would use an analog multimeter to test for power at that first splice. You may be able to get a reading by inserting one probe into each wire nut, or you may need to remove the wire nuts and separate the wires before testing. You're looking for 120V across the two conductors in the cord coming from the wall plug.
