Unhappy Honda Rincon-Fan not working

I have a honda rincon 650 (03 or 04) and am having issues with the fan. When I run the 4-wheeler, it overheats after about 5 to 10 minutes. I assume this happens because the radiator fan is not clicking on. I checked the fuse and it is fine. I also checked the fan thinking the motor went out but it is fine as well (ran it straight to the battery and it turned on immediately). My thoughts are maybe the sensor that turns the fan on is bad. My question is - where is this sensor? Any other ideas? And does anyone have a wiring diagram/engine schematic that may be of any help?

Thanks in advance!
Chris

One thing that makes me wonder a bit - when I cut into the tape, a bunch of water came out.... hmmmmm.

I am going to try to attach a couple of pictures.

My question - What do I do with this now? A fuse is bigger than the little black fuse that is in there...

hello, good morning, I have the same problem of not running the fan, where you found the breaker?
Thank you very much
sorry my English but I'm from Spain.

No luck .

I ran it and overheated it with the original fuse in that switch. Then I popped out the fuse and stuck a wire in from one pin to the other. Still didn't turn on...

I'm wondering if thats the breaker we're looking for. Without the fuse (and no wire), everything gets power with the key on but it won't start. As soon as I bridge the connection, it will start right up.

I was poking around a bit under the front where all the connections are and noticed this:

Any ideas what that is? I'm not sure if theres a cover on it that comes off.

At first glance, it slightly reminded me of a plug to pull codes.

Hello, and thanks for the info, this weekend I look.
I have another small question, 12: THERMO UNIT, cylynder head, where he works in the cdi? or the light from the dashboard? or the fan?.
And the 14: SENSOR ASSY. 1741467-001, of the REAR CRANKCASE COVER? is for oil pressure or temperature?

Thank you very much.

jp33 - I'm not sure I know how to answer your questions.

The 'breaker' I found, I don't believe it is the breaker I was looking for. I found a second one taped into the wiring harness. Neither have a reset switch (I pulled one apart a bit).

I tore into the wiring harness and didn't find any cut wires. I am going to look closer tomorrow but I think everything looks fine.

I have a couple pictures here for ya.

First off, when I removed all the tape and wire covering, I found a lot of connections that looks like this:

I haven't taken off the electrical tape but it looks like wires were joined together with just electrical tape? Strange...

Also, this little gray box:

does come apart to reveal this:

Any ideas what that is for?

Good day ....
what a mess of wire!
this afternoon (Spanish time) I watch the wires with a continuity tester and I will tell you
I do not know what is the gray box, but I think it is a connection to the Honda tester. ?

It's more towards the right side of the atv but it's basically right below the gas tank in the open cavity in the frame where all the other connectors are.

No I haven't found it. I'm going to go out in about an hour and follow all the wires from point A to point B. I figure between the fuse box to the switch to the fan I should find a breaker connected in line. If it's not found, do they make four wheelers without them?

Yeah all are good. I made sure to check those first. I had a fuse go out a year ago but didn't check it and ended up waisting my time and money on replacing the fan motor. That was definitely frustrating when I found it was the fuse!

Red face

I think my temporary wires were loose when I said I had to shake the fan to get it to kick on.

I just called my local Honda atv dealer and talked to a guy in service. He listed off everything to check in this issue:

Fuse
Fan Motor
Thermostat Switch
Coolant Sensor (the sensor in the cylinder head)
AND...
Oil Sensor

I haven't checked this yet. He said he has seen a few come in that had a bad sensor or the wire was loose. For anyone else trouble shooting, I'm told it's located underneath towards the rear of the four wheeler. I may have to remove the skid plate as well.

Since I haven't checked this yet, I'm going to go out and see what I can find. I'll post back as soon as I have some more info.

Chris
