How To Wire Auto Electric Cooling Fan 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. Start with taking both of the positive wires from the fans and connect them to the yellow wires on each relay. you will then need to run switched power (usually from your ignition switch, but modern replacement wiring harnesses usually have a fused fan relay trigger wire) to the blue wires on the relays. next, both of the black wires from the.
Electric Cooling Fan Control Wiring Diagram Common issues with auxiliary fan wiring. the auxiliary fan is an important component in a vehicle’s cooling system, helping to dissipate heat from the radiator. however, like any electrical system, the wiring for the auxiliary fan can sometimes encounter issues. here are some common problems that can arise with auxiliary fan wiring: 1. wire. 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. 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. Jimlev. 7758 posts · joined 2003. #2 · oct 3, 2011. yes that is the power connector for the fan. there are 2 different aux fans and speed control circuits. the older cars that use a throttle cable have a temp switch on the side of the radiator that controls power to a 3 speed fan. relays and resistors are used for the different speeds.

Hook up the fan, let the car run for a bit and see if the aux fan is working, there is no guarantee it will work, because the engine needs to be at a certain temp. put everything back together again. go to autozone, buy r134a with a guage, turn ac on at 60 and fill the ac to the blue level of the guage. Follow these step by step instructions to wire your electric radiator fan: first, gather all the necessary materials and tools for the project. this includes the electric fan, relay, fuse, fuse holder, wire, connectors, and a wiring diagram specific to your vehicle’s make and model. locate a suitable location for mounting the electric fan.
