I just put a new awesome setup on my scrambler, It is a switch so I can switch on my cooling fan whenever I want to, since my temp sensor broke. Here's the instructions(sort of) of how I did it.

First you will need three pieces of wire, I don't know what size, but on my wire strippers, they fit in the second to last hole. Remember, I an 15, so anybody can do this. You will also need some wire splicers, and a on/off switch that mounts to your plastic.

Ok, splice one wire into the black wire comming out of the fan, and splice the other end of that wire into any brown(ground)wire.

Splice another wire into the red wire comming out of the fan, and connect it to one end of the switch. ok, follow the wires coming out of the fan up to a black bag. comming out of the far end of that bag is a red wire with white stripes. Splice the third wire into that wire. The other end of that wire should be connected to the other end of the switch.

Now drill a hole in the plastic, where you please, and mount the switch.

I can give any more info if needed, but I think that's pretty much it. Oh yeah, and I covered all connections with some liquid electrical tape to waterproof the connections.

I can send you pictures of mine mounted, if needed. Glad to help!

 

Let us know how this works over time, i thought about doing this as well to my scrambler. I have run that set up on my last two street bikes. I wanted to be sure they would not over heat at long stop lights and so on. I was more worried that if i shut them off i would not be able to get them started when the light turned. I guess that is not that much of a problem with quads as far as stop lights go. I hope it works for ya.

 

This is a must on a Raptor. The temp switch is junk so I just add a switch and turn the fan on during a hard ride. It works great. I also added a pilot light on the bars to tell me when the fan is on.

 

Another idea is to move the overtemp light down to the bottom of the warning light cluster, especially if you have a tach mount that might obstruct your view....and probably only if you've removed the oil injection. Which leads to the next idea....wire up the oil injection warning light to the fan temp sensor, so you can monitor if you are getting your temp up to the range of fan engagement. This is for those of us who have removed the fan and are running Red Line's Water Wetter. And remember it doesn't have anti-freeze properties...if you live up north dontcha know. Good idea with the switch Adam.

What's that water wetter? Does it help temps? I live in texas, so freezing isn't a problem.

 

Hey Guys,
I have a 97 Sport 400L. How often should my fan come on when it is pretty warm like in the middle of summer? Mine hardly never comes on and I was wondering if something was wrong with it. It might come on every blue moon for a minute or so. I have a friend who has a explorer 300 2 stroke and his seems to stay on ..but it is air cooled.

Thanks,
J Prentice

 

I know, mine did the same thing. I think the wiring is cheap, so it only works some time. Do what I did. It's awesome.

 

This could help.

My 2000 Scrambler 500 4x4 was doing the same thing (temp light) and I traced everything that I could short of pulling the water pump out. I changed the temp sensor and it didn't change a thing. The sensor is located at the TOP of the radiator (the 2002's are located at the bottom of the radiator). What happens is the fluid level drops down below the sensor and it dosen't turn the fan on. The sensor will NOT turn with the heat of the air, it has to be in contact with the fluid. What you need to do is completely fill the radiator to the point that it spills over when you put the cap on and your overheating problem is fixed!! Believe it or not. I spent a lot of time thinking it was something big, all I needed was a little bit of fluid.[img]i/expressions/face-icon-small-happy.gif[/img]

 

Water Wetter is made by Redline. $8 gets you a bottle, follow the instructions, and it can drop your cooling temps up to 20 degrees.
Regular maint. like spraying your radiator clean after muddy runs is also a good idea.

Hey, had my switch on for a week, works great still
