How to Wire a 12 Volt Fan
Wiring a 12 volt fan is possible in any environment were 12 volt batteries are the power source. Whether a boat, automobile or house battery bank is the power source, the methods are the same for wiring a fan or any other of a long list of 12 volt appliances. Only two wires, a positive and a negative, are necessary. Properly sized wire is also necessary to control the voltage drop from the fan to the power source.

Measure the distance from your battery source to the location of the fan. Include in the length any turns or extra footage required for the route. Refer to a wire chart to select the proper gauge and type wire for your project. Marine applications require different considerations than land-based wiring of 12 volt fans.
2Disconnect the battery by removing the cable to the positive terminal. Attach one end of the positive wire to the cable that will be reconnected to the positive side of the battery. Attach the other end to the positive connector on the fan. Attach one end of the negative wire to the negative connector on the fan, and attach the other end to a ground location or the negative side of the battery.
3Reattach the batterys positive cable to the battery terminal. Test the fan by flipping the on and off switch.
4Attach the wires at several locations along the route with wire clips to prevent the wires from chaffing or being damaged later. Place them behind trim to hide them from view.

How to Adjust a Horton Clutch Fan
All automotive engines use a fan to keep the engine cool during operation. If you are having problems with your engine overheating, it could be due to the Horton clutch fan installed in your car. When the fan does not operate, the engine overheats and turns off. As this could happen during operation, adjusting the Horton clutch fan could keep it attached to the serpentine belt on your engine. You dont have to be a car mechanic to adjust the clutch fan. You can do it yourself with little hassle.

Park your car on a level surface, and apply the emergency brake. Pop the hood, so you gain access to the engine.
2Use a socket to remove the upper fan shroud from the Horton clutch fan. This is the protective piece on the top of the fan.
3Use a belt tool to suspend the serpentine belt. Make sure that the serpentine belt is making contact with the Horton clutch fan. Adjust or replace the belt if needed.
4Use a socket set to loosen the bolts securing the clutch fan to the car. Adjust the fan so you can get a good fit on the serpentine belt if needed.
5Tighten the bolts and situate the serpentine belt to the fan. Release the belt by removing the belt tool. Close the hood.
