Hey, I have a set of EF thermo fans here, the fan that only has 2 wires seems to work fine, but on the one with 3 wires, if I hook up negative, and then hook positive to the white wire, nothing happens, and if I hook positive to the red wire, it works as it should, is one stage of the fans stuffed or have I just wired it wrong?

Cheers, Gab

Check between all wires for the ohms of each stage Gab and let us know what you find?

Cheers,
Tim

That's gonna have to wait until I get a new multimeter. Mine got misplaced awhile back. Probably buy another on this coming Friday.
