Dual Electric Fan Relay Wiring Diagram Optionally, a single high current relay could be used to control both fans. the supplied diagram below using dual relays with a single temp sensor is both the most reliable and easiest method we've found for wiring dual fans. it uses our 40 amp electric relay kit and electric fan sensor. the relay isolates the high amp load of the fan circuit. With dual cooling fans, there are two methods for wiring up the relay kit. this is based on the draw from the fans, if the fans are larger and draw more than 15 amps each, it's recommended to install a second relay kit as shown below. for smaller fans, both fans can be connected to a single relay as shown above, and the proper fuse should be.
Relay Wiring Diagram For Dual Fans Wiring Work A dual fan relay diagram is a schematic representation of a circuit that controls two electric cooling fans in a vehicle. the diagram shows how the wiring and components are connected to ensure proper operation of the fans. it is commonly used in automotive applications to regulate the temperature of the engine and prevent overheating. 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). then connect switched power (usually from your ignition switch), to the blue wires on both relays (tab 86). next, splice together both black wires from the relays (tab 85) and connect them to the thermostat. Yes, you can. but it is risky. the electric cooling fan setup has a high amp draw on start up, which can blow the 30 amp fuse that protects the relay and wiring. most relays have a 30 amp fuse. if this fuse blows, the cooling system goes offline, meaning the engine will overheat. a dual fan setup with a large and small fan. Overall, the wiring diagram for a dual electric fan relay provides a comprehensive guide for properly wiring the system. by following the step by step instructions and carefully connecting the components, you can ensure that your dual electric fan setup is wired correctly and ready to keep your engine cool.

Overall, the wiring diagram for a dual electric fan relay provides a comprehensive guide for properly wiring the system. by following the step by step instructions and carefully connecting the components, you can ensure that your dual electric fan setup is wired correctly and ready to keep your engine cool. The wiring diagram for dual cooling fans typically includes a relay, a fuse, a temperature switch, and the fans themselves. the relay is responsible for controlling the flow of power to the fans, while the fuse protects the system from electrical overloads. the temperature switch senses the temperature of the system and activates the fans when. Here is the circuit diagram for wiring dual cooling fans: dual fans relay wiring circuit diagram. we recommend using a 40a relay because it is easy to work with and can handle the circuit’s current demands. you will note that the dual cooling fans feature positive terminal wires that are marked. connect these wires to the relay’s yellow wire.
