Wiring fan help

[munro]

So I bought some 90mm computer fans off Craigslist for my Irish coffin keezer. I took a 120v - 12v step down transformer/charger and hooked it up. All the fans worked great. So then I twinned the black wires from 2 fans and the red wires together and tried it and nothing worked. And now none of the fans work at all! Any input? Did I burn something out?

Try each fan separate if the fan draw is to high the transformer may not have enough power to run both

I tried to do them separately and now they won't work. I'm assuming I drew to much from the charger?

Do you own a voltmeter?

did you see smoke if you acidently put 110 you might have fried them the smell of the center of the fan should not smell burned if it does there fried wish i could help more

If you let the smoke out, it's probably broken. Also try smelling them, see if they spin easy?
