Wiring Diagrams For A Car Radiator Fan 12v Dc 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. 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.
Wiring Diagrams For A Car Radiator Fan 12v Dc 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. 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. 3 pin and 4 pin fan wire diagrams. 3 pin fan connections. *cable coloring varies from fan to fan. pin name. color. color. color. color. 1. The fan's bearings are failing causing the motor current to increase when the fan gets warm. if the fan was taken from a vehicle that has a 12 volt electrical system, a 12 volt power supply that has an adequate current rating is what should be fine. a battery charger probably has an output of 15 volts or so. the vehicle may output 15 volts when.

Lastly, connect a fused constant power to both of the red wires on the relays. this is the load side of the relay and you should use a minimum of 14 gauge wire here. the white wire on the relay pigtail will not be used. with these dual fans wired up you can keep your car cool and not have to worry about clearance issues!. 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. if the fan still doesn’t run, provide battery power and ground directly to the fan. if it doesn’t run, the radiator fan is bad. check condenser fan relay operation.
