Radiator Cooling Fan 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. 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).
Wiring Diagram For Dual 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. 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. Wire the relay to the power source: connect the relay’s positive wire to the power source, usually the positive terminal of the battery. 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. 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.

This video shows how to easily wire an electric radiator fan circuit into any car. this fan wiring diagram includes a fan relay, a temperature switch, and a. 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.
