Orange : Connect to ignition switch +12 vdc when engine is in run position. (Hook to constant +12 vdc for the fan to run continuously when the engine is hot even when the ignition switch is off). Black : Connect ring terminal to chassis ground.
What are the symptoms of a bad cooling fan relay?
1. Engine running hot One of the first symptoms commonly associated with a bad or failing cooling fan relay is an engine that runs hot or overheats. If you notice that your engine is running at higher temperatures than normal, that may be a sign that the relay is not functioning properly.
Where does the wire go on a radiator fan?
The black wire that comes attached to the fan controller attaches to a good ground. The female blade terminal attaches to the red wire on the fan. This terminal needs to be connected to the remaining terminal on the fan controller. A terminal needs to be attached to the black wire on the fan and ground to the frame.
How do you turn off a radiator fan?
The fan can also be turned off manually when cruising to extend the life of the fan. Install the inside toggle switch where convenient. Remove the radiator fan relay from the fuse and relay box on the fender well.
How do you connect a fan to a receiver?
Connect the blue wire from the fan to the blue wire from the receiver. Connect the black wire from the fan to the yellow wire from the receiver. All wires, even if not connected to another wire, should now be capped with a wire nut.
What happens when a radiator relay goes bad?
A faulty or broken relay cannot deliver power to the cooling fans. In turn, the unpowered fans won’t run, leaving the radiator to its own devices. Deprived of the helpful influx of air from the cooling fans, the radiator cannot remove as much heat as it usually does.
How do you connect wires to a ceiling fan?
Connect the black and blue wires in your fan if you only have 1 switch. Connect the black and blue wires coming out of your fan. This will allow you to control your fan and lights with a single switch. Twist the copper ends of the black and blue wires together like you did with the previous wires.
What is a wiring diagram for a fan?
Electric Fan Relay Wiring Diagram – wiring diagram is a simplified tolerable pictorial representation of an electrical circuit. It shows the components of the circuit as simplified shapes, and the capability and signal contacts between the devices.
Where is the fuse on an electric fan relay?
The orange wire on the relay should see a 12 volt signal when the ignition switch is turned on. The other two wires on the relay are the meat and potatoes of the system, with the yellow wire connecting to the battery along with the supplied fuse mounted within 12 inches of the battery.
The red wire from our relay connects directly to the cooling fan, and the black wire from the cooling fan connects to ground, both wires will utilize our supplied fan harness.
Where do you put the fans on a van?
& FRONT! We see many people with 2 fans on their van: one in the front, one in the back. Typically, one fan acts as the intake (OFF) and the other fan acts as the exhaust (ON). People with this setup are really happy about it, as it creates excellent ventilation.
What’s the best way to wire a ceiling fan?
Connect the black wires together. Lastly, connect the blue wires together, or the blue wire to the black wire for lights. For ceiling fans without lights, follow the same step. This will allow you to add a light kit later on without having to rewire the fan.

How do you connect a radiator fan to a hot wire?
Turn the key on and check for a second terminal to have power. This is the one from the key that will be used to actuate the relay. Mark it down. Put the voltmeter on ohms and check the remaining two terminals for a ground. Mark the terminal showing ohms down as a ground. The last terminal is the one to the fan.
Can a 4 pin fan be connected to a 3 pin fan?
Please Note: Some fans may have a 4 pin connector but only 3 wires going into the back of the connector. This is still considered a 3 pin fan. 1. A 4 pin PWM fan connector will have four square holes on the front and four wires entering the back.
What are the colors of a fan wire?
3 pin and 4 pin Fan Wire Diagrams Pin Name Pin Name Color Color 1 Ground Black Black 2 +12v Red Yellow 3 Tach/Signal/Sense Yellow Green 4 Control/PWM Blue Blue
How do you connect a 4 pin fan to a motherboard?
1. The fan connector will have two guides (1) and these will need to line up with the tab (2) that is on the motherboard fan header. 2. Next, press down until the fan connector is fully connected to the motherboard header. Installing a 4 Pin fan to the motherboard:
How to disconnect electrical connections to a radiator fan?
Lift the clip before pulling the male and female plug housings apart, if your plug is so equipped. Use the blade of a slotted screwdriver to lift the clip if you are unable to pull it up with a finger. The plug carries all electrical connections to the fan. Once it is unplugged, the fan power is disconnected. Jonra Springs began writing in 1989.
Do you need a relay kit for a cooling fan?
A relay kit, our part number CCFKRL, will include everything you need to properly wire up your electric cooling fans, with the exception of additional wiring needed to complete all of the circuits. The first part of the installation is to install the electric fan to your radiator, and remove the mechanical fan.
What kind of fan controller does a Dodge have?
Some Dodge vehicles have a solid state radiator fan controller that varies the fan speeds by pulsing the ground to the radiator fan motor. But other Chrysler and Dodge vehicles use a more traditional radiator fan relay. This is the Dodge Radiator Fan Wiring Diagram for the traditional version.
How does the radiator fan work on a Dodge?
This is the Dodge Radiator Fan Wiring Diagram for the traditional version. The powertrain control module (PCM) sends a reference voltage to the engine coolant temperature sensor and monitors the return voltage. When it determines the engine requires cooling, it grounds the control coil in the radiator fan relay.
How to troubleshoot an electric cooling fan problem?
1.Has the Cooling Fan Actually Failed? 1 If the fan comes on when the AC is running at MAX, but doesn’t run when the engine is hot, check the temperature sensor… 2 If the fan fails to come on, first check for a fan blown fuse or triggered breaker. On older vehicle models, you may… More …
What kind of wiring do I need for a cooling fan?
The cooling fan wiring diagram below is what we’ve found to be the simplest and most reliable method. It uses a 40-Amp Electric Relay and Electric Fan Sensor. Start your wiring project by taking both of the positive wires from the fans and run them to the yellow wires on each relay (tab 87).
