Wiring Diagram For Electric Radiator Fan Wiring Diagram 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. Step 3: install the electric fan relay. after wiring the electric fan to the proper power source, the next step is to install the electric fan relay. the electric fan relay is an important component that controls the operation of the electric fan. it acts as a switch, turning the fan on and off when needed.
How To Wire A Switch To Radiator Fan At Cindy Ware Blog 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 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. Member. may 17, 2017. #1. this modification will allow low speed fan operation at a lower than stock temperature, without setting any codes. this is a 3 speed fan, with two resistors built into the fan motor itself, to limit motor current on the two lower speeds. there are a total of five fan control relays. Locate a suitable location for mounting the electric fan. this is typically on the front side of the radiator, but can vary depending on the vehicle. ensure that the fan is securely mounted and positioned to provide optimal air flow through the radiator. determine the power source for the fan. in most cases, this will be the vehicle’s battery.

If you don’t get ground on pin 3, the ecm is not activating the radiator relay. that can be caused by a faulty engine coolant temperature sensor or a wiring problem between the ecm and pin 3. if you do find ground on pin 3, jumper across pins 1 & 2 in the socket. if the radiator fan runs, then the radiator fan relay is bad. replace it. Always start by checking the fuse for the radiator fans. it’s located in the integrated power module in the engine compartment. if the fuse is good, move on to the radiator fan relay. using the dodge radiator fan wiring diagram above, you’ll see that the relay ground is at g102 and the control coil receives power from the pcm.
