Dual Electric Fan Relay Connections 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. How to wire dual electric cooling fans.
Dual Electric Fan Relay Connections 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. There are quite a few options when adding an electric fan to your muscle car or hot rod project. one common configuration is to use a dual fan setup in order. There are several ways that a dual fan can be wired. for example, dual thermostat switches or dual relays could be used to control each fan separately. or a single relay could be used to control both fans. 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. 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.
