Electric Cooling Fan Circuit Diagram How to wire dual electric cooling fans. 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.
Electric Cooling Fan Wiring Diagram For Your Needs 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). How to wire an electric radiator fan relay temp sensor. If you're still not sure, once you've completed all the wiring, let the car warm up to temperature, and once the fan kicks on you will be able to feel if it is pulling air from the front of the. 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.

Connect the relay’s negative wire to a suitable ground connection. test the fan: after completing the wiring process, test the electric cooling fan to ensure proper functionality. turn on the ignition and observe if the fan starts running. also, check if the fan turns off when the ignition is turned off. Here are some tips to help you with the wiring process: 1. use the correct wire gauge: when wiring an electric fan, it is crucial to use the correct wire gauge. the wire gauge should be suitable for the amperage rating of the fan. using a wire that is too thin can cause overheating and potentially start a fire. 2.
