I wanna hook a toggle switch up so i can turn the fan on when i want to. I have a 2005 450R has anyone done this on a 05 i have seen it done on 06+ ? And have Pics and info.
Thanks

I haven't done this, but I think I know how to do it. There are two wires coming out of the fan - hot and ground. You will want to splice the switch into the hot wire. Then you will want ground the temp sensor, which is the wire right above the thermostat housing. I'm pretty sure that's all you have to do.

The fan wire is the blue wiring housing are you saying splice into that?

Yes, I believe that is correct. One is ground, and one is hot. Cut the hot wire, and the ends you cut will go to each side of the toggle switch.
Now that I think about it, you could probably do either one of the wires and it would work, as long as the wire above the thermostat housing is grounded.

Before i start hacking the wiring i'll shove1 of the wires(off the toggle it has 2 but it doesnt matter ) into the blue plug in(pic above) and take the other wire(on toggle) and wrap it around the thermostat wiring (that connects into the thermo) and i will ground both of them and we will see.

Scro is close with what he is saying if you want the fan to stay on all the time just ground the wire from the temp sensor on the head. If you want 100% control over the fan disconnect the wire from the temp sensor and hook it to a switch...then run a wire from the other side of the switch to ground and every time the circuit is closed the fan will come on.
now if you want it to come on normally or when you want it to then leave the wire plugged into the temp sensor and splice into it to one side of the switch then the other side to ground now the sensor will activate it normally or if you feel you want it on you can close the circuit manually

Neither of the above ways works. My fan is fine and does work i tested it out by putting jumpers to a battery..Here is a little ifo
Its a 2005 trx 450R
Removed headlight
Removed on/off/light switch
Removed rear brake light
It has a killswitch wired in (gounded at the coil)
Maybe this toggle switch can not be performed on a 05 do to there is no battery ?

When you grounded the wire above the thermostat housing with the quad running, the fan should have come on. If not, there is something else wrong.

I did all kinds of combos only to get more and more pissed off. I ran a jumper from the wire(Above the thermo) to the coil for ground..Didnt work also to the frame same results.And in the process i had a jumper wire to the fan hot wire(Blue pic above) nothing. For some reason i dont think you can do this to kicker 450Rs only er's . Because where is the voltage coming from ? I was told and im starting to believe them that if you remove the on/off switch and headlight your fan will never work.
......I mean i can ride it for awhile but it gets hot and boils in the rad and starts to come out the over flow tube. What the point of that if i go trail riding i d have to stop every half hr . I guess i ll just sell it like planned.

did you try splicing into the red wire at your condenser to power your fan
Latemodel32
04-05-2010, 07:03 PM
ya know i looked at that but didnt try it. So what do you suggest trying. Splice into the red on the condenser and the other end to the blue wire(fan motor)? Confussed lol

I may be asking the obvious, but is it running when you trying these things?

yea red to blue with your jumper wire at the fan then ground the green wire from fan to a good spot on motor or frame then start your quad and see if the fan runs

Yes its running i should have mentioned that lol
I was told on another forum i need the key/assembly hooked up to get the 12v to the fan.
I still have everything i took off and i'll try there method when i get time.
Key turned on(and plugged back in) splice into the fan wire then to the toggle from the toggle to the temp sensor to ground. We will fig this out yet guys i promise:D

aaa yes you need the key hooked up for it to work

When the AC is used, it overrides the temperature switches and turns the fans on to assure there is sufficient flow through both the radiator and the AC condenser. A bad fan switch does not prevent the AC from running the fans. So my guess from here would be to replace the fan switch or relay. Since you already replaced the sensors you know they are good, and since your fan comes on with the AC you know that it is good as well, leaves only a few components. also of course check for any loose or broken wiring form the sensors, etc.
Great problem but surely frustrating for you and I do wish you good luck with it.

Hi there,
Have you removed and tested or swapped out the coolant thermostat? If this fails shut it can block off the radiator from the hot water. Not very expensive to do if it is accessible.

When connecting an exhaust fan, you must follow a few rules that will not be superfluous to repeat:
Connection of 220 V is made to the fan through the built-in terminal box. It is located under the front cover of the fan. All terminals on the fan are signed.
If you need to connect a fan without sensors, then this scheme is for you. Any standard key switch is suitable for this task. As a switch, you can use the RS-1-300 speed controller, which is built into a standard mounting box.
This speed controller can turn on the fan and change the performance of the hood. With a decrease in performance, the noise level decreases, if you need a quick removal of air, you can select the maximum performance. nine0003
The fan is turned on and off with a cord attached to the fan casing. Phase and zero are connected to the fan.
These fans are most often used to ventilate kitchens or other rooms where power is already supplied to the installation site without the possibility of removing a separate switch.
The wiring diagram for a fan equipped with a timer and a fan with a humidity sensor is the same. The fan with a timer starts its operation when voltage is applied from an external switch to the LT terminal. After pressing the switch button, the fan will continue to work for the time set on the timer. Such a fan can be tied to turn on along with lighting.
It is advisable to use this fan for exhaust ventilation of toilets and bathrooms.
The fan with a humidity sensor can be turned on by force or it turns on automatically when the set humidity level is exceeded. Humidity is set in the range from 60 to 90%. The fan will work until the humidity drops to the required level, after which it will work for another time according to the delay timer and turn off.
These fans are used to ventilate the bathroom, laundry or drying room. They are also used for exhaust ventilation of the basements of a private house with a high level of humidity.
The fan turns on automatically when a person moves at a distance of 1-4 meters with a viewing angle of 100. After the person has left the room, the fan will continue to work for the timer and turn off. The delay time can be set under the front panel of the fan from 2 to 30 minutes. nine0003
Like a fan with a switch cord, such a fan can be installed for ventilation of rooms where a constant phase and zero are connected to the fan installation site and it is not possible to install a separate external switch.
