What is the yellow wire for on a fan?
Blue and Yellow Electrical Wires Yellow wires are used as switch legs to ceiling fans, structural lights, and outlets paired with light switches, while blue wires are usually used as travelers for three-or-four-way switches.
How do 3-wire fans work?
In a 3-wire fan, first two wires are the power supply wires of the fan. The third wire, comes directly from the output of the built-in ‘Hall Sensor’ chip generates output pulses during the fan rotation. With the help of this third wire, a monitoring circuit can ‘see’ the rotation.
Which is wire is negative on this PC fan?
It shows the same pin (2) as positive, but the colored wires at top left are incorrect. White stripes don’t necessarily mean anything – the manufacturer might have just used what was available, and the white stripe might be for the tachometer or was ignored completely. – JYelton Apr 29 ’14 at 18:53
What kind of wire is used to turn on a fan?
SIGNAL CIRCUIT 12V SWITCHED (IGNITION OR FUSE PANEL) Power “ON” when key is in the “RUN” position. 1ST RELAY TURNS ON FAN WHEN TEMP SENSOR IS ACTIVATED BATTERY 86 30 87 85 12V SWITCHED WIRE TO GREEN WIRE AT A/C CLUTCH. NOTE: OR IN AN ’84 TO ‘89 240 YOU MAY USE THE A/C POWER ‘ON’ WIRE: RED/WHITE WIRE AT AC SWITCH MICROSWITCH IN DASH.
How do you wire an electric fan motor?
By connecting the positive terminal to the positive terminal of a DC power source, such as a battery, and then connecting the negative terminal of the motor to the negative terminal of the power source, the motor will run. The power source must be able to supply the power requirements of the motor. Verify if the motor is AC powered.
How big of a wire do I need for a fan?

What should the ground signal be on an electric fan?
The temperature sender, if used, is designed to provide a ground signal at about 185 degrees, and will shut back off when the temperature drops below 165 degrees. This wire (gray in our kit) supplies the ground signal to trigger the relay. The orange wire on the relay should see a 12 volt signal when the ignition switch is turned on.
