30 Amp Relay Wiring Diagram Electric Fan

Each relay will control a single fan and a 30 amp fuse is recommended for each relay connection to the battery.

30 amp relay wiring diagram electric fan. Lets say we put both fans in series. Suggested electric fan wiring diagrams converting a 12 volt switch into a ground switch these diagrams show the use of relays on off sensors on off switches and on off. 30 other red wire needs constant 12 volt power from the battery. I would think 85 would be connected to 30.

86 gray white wire goes to the ignition switch. But i have a question about this wiring diagram. As you can see from the diagrams above and below it s really a simple circuit that not only provides the proper connections to control the cooling fans but unlike the switch under the dash method you won t ever have to worry. Ok here is a true 2 speed fan control.

Install a 10 gauge wire to the battery positive terminal with the use of a round electrical connector. Find a spot to secure the relay with a screw or a bolt. That doesn t seem right. 87 red wire connects to the positive wire on the electric fan.

Wiring a electric fan with a relay i am getting ready to wire my electric fans and did some searching and found this thread. I want to wire it like post 11 diagram 2. Purchase a 4 post relay with a 30 amp rating. Fan speed control the idea here is that fans are 12 volt motors and typically will work at reduced capacity at a lower voltage.

Locate the relay in immediate proximity to the fan being used. It shows the dash switch relay terminal 85 to 87.
