Re: question about the sticky " Wiring an electric fan with a relay "
It should work if it's wired like the schematic. I don't think it's a real good idea to run a 2-speed fan on high speed only, the inrush current is quite high, and low speed is usually sufficient for all but the hottest situations. If you want a fairly inexpensive 2-speed alternative, look for a Volvo fan control relay.
