Electric Wire Diagram 12v Cooling Fans Wiring Diagram Elec 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. How to wire an electric radiator fan relay temp sensor.

12v Fan Wiring Diagram 30: constant 12v, unswitched 85: signal (switched 12v) 86: ground (completes circuit) 87: consumer (fan) 12v 87b: extra consumer (same as 87) 12v switched wire. may be 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 to wire electric radiator cooling fans using the alloy works relay and temperature switch kit. this kit can be purchased here: alloyworksplus. 87 (red wire) connects to the positive wire on the electric fan. 30 (other red wire) needs constant 12 volt power from the battery. 86 (gray white wire) goes to the ignition switch. 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.

Wiring Diagrams For A Car Radiator Fan 12v Dc 87 (red wire) connects to the positive wire on the electric fan. 30 (other red wire) needs constant 12 volt power from the battery. 86 (gray white wire) goes to the ignition switch. 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. 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. Understanding the basics of the 12 volt electric fan relay wiring diagram can help you get the most out of your cooling system. the diagram consists of several components that work together to control the fan’s operation. first, there is the relay, which sends power to the fan when the temperature of the engine reaches a certain threshold.
