Good Evening all
I went to Mt Blue state park (Maine) Wed for a little ride... Oh let me tell ya....
Lets just say it was a experience. I went off the edge of a log mat, which was under 8" of water... I didn't know it was there until I lost my rt front wheel and the whole rig was leaning over on its side to just about the tipping point. F U D G E....
well I shut her down so as to not wash the inside as well as the outside had been done. I stupidly got off on the low side to try and crab it back on to whatever it fell off of. When I went to dismount it I found myself not feeling the bottom. Once I did the water was over my waist. I had about another 50' to go to get to the exit. I had about 40' to some small trees. I grabbed the strap out of my box, wrapped it around the closest tree and winched the rig out of a real bad spot. I have to say the winch saved my ass pretty good. Once the water drained out of everywhere... I got going again. I was on my way to view a piece of property and still had a ways to go. The riding was very boney and rocky with washouts and roots everywhere. my speed was pretty slow 5 - 8 mph. So I'm going along like that and the next thing to happen is I get the whole high temp alarm full bars nonsense. Oh shit the fan isn't kicking on! WTF is this? So I shut it down for a bit, then ran it, then shut it down... Once I had some clear trail where I could run it up over 20mph she cooled down but the slow stuff was killing me. As it so happens on one of the faster sections I just clipped a rock or maybe a root just the right way and got my first flat. LOL you can't make this up. I stop and I check it out. I couldn't see the gash that was in there so I figured I probably hit it in such a fashion that maybe i unseated the bead and I lost my air. Ah yea. um nope


5 plugs and some real nice guy with a portable compressor helped me out. I had a tire patch kit with the co2 and all that but I went through the co2... so I will replace that and probably just buy another kit and combine what I have. Anyway he got me going again. I bailed on looking at the property at this point and figured I just better make my way back. I retraced my path to the point where I could take a different route to avoid another bath.
Nursed her back to the truck.


Now I have to deal with the tire issue. Not a big deal. What I am doing now is troubleshooting the fan issue. I am following the service manual to figure this out but I have a couple of questions.
First one, is the fuse a 40 amp or 30 amp? the manual says 30 but all i could find was a 40 on the rt side.

could this be the one? If it is then the fuse is good, not burnt. 2nd question, according to the manual it says make a jumper to bypass the relay. I did this but I assume you have to have the engine up to temp so the fan will kick on and not cycle? Is this correct?

The relay block all looks good and dry with no visible issues. I will check the ohms like the manual says but Im not too sure which pins to test and my multi meter has a ohms selection but again Im not sure which to choose from... maybe the lowest. i Guess.

Well Thanks for the ride along if you hung in here this far I owe you all either beers or cigars and or whiskey. I am grateful for this forum without it I would definitely would of had a much worse time.
Thanks

Well...adventures come in all shapes and forms. Some are challenges..and this one appears to qualify as that.   On the fuses, there will be two large fuses-one for the system which also feeds the fuse box for breakdown and the other for the power steering drive motor. I suspect the systems power is that 30 amp and the motor is that 40 amp. The fact that it runs says the systems main fuse is OK.

On the relay, the ECU by way of the heat sensor provides either power or ground to the coil of the relay, closing a contact between two other posts that supply power to the fan. If you jumper the right two posts the fan should come on. If it doesn't, there will be a fuse in that distribution fuse box just for the fan that is likely to have blown if the fan motor got wet. If it is not blown test for power in and out of the fuse box and to the relay, then to the motor itself. If at the motor's connection it has power when jumpered and the motor won't run, check it for being siezed-up and it's ground. If it OK, then the motor has likely lost a winding and failed. 

Ok. On it.
Update the relay appears to be good I  swapped it out and I also jumped it... now on to your steps... thanks .will update as I go... just text me the address where to send your evil of choice

Lol..no need. Just happy to help.

So I had a blown fuse 15 amp in the little fuse box, replaced that still no fan. Next step lok for power going to that fuse. No power going to the fuse.
Checked the power at the relay and there was some 12.4v.

The wire going into the fuse box is a red and a green w/brown tracer I guess I have to chase that down now...

I popped the connector off of the thermostat and that seemed ok... tough to get to the fan even removing the front inner wheel skirt.

Just want to make sure I am testing power into the fuse block correctly.  I just pulling the new fuse and checking to see that there us power there with the key on? Is this correct? Or do I have to wait until it gets up to tenp for that to register?

I can send ammo to... just saying

Depends on how it's wired. What year and size is this? I might have a wiring diagram close enough to tell us. Put it in your signature line.

From my manual

Oh you have one. Just trace it from the fan motor back.

I'm at a wedding rn... when I get home I'm gonna pull the connector from the fan. Connect to the battery to see if the fan will run if it does then great. I'll have to try and trace the rest of the system out.
Enjoy your day and thanks again...
I'll update tomorrow.

Fan motor works
Relay circuit works
Fuse is new
Last thing would be the temp sensor according to the service manual.
Will try that next.

I ordered a temp sensor I'm just going to replace that. The testing of one seems like a wast of time I'm just going to swap that out for $40 and see what happens.
I have to go back to work for two weeks so when I get back I'll get that done.
Everyone that has read all this, thanks. Enjoy your week, keep your powder dry. You never know.

Befor i went back to work, I bought a OBD2 tool from the zon...
Bluetooth, it was asking for the make model ect stuff... obviously the one I bought didn't have cfmoto as a choice so I picked the next best thing...

Ssangyong... whatever that is. I plugged it in and check for codes, there was one.. some exhaust something or other nothing else though. With the bike running it showed the rpms, hrs, coolant temp and so on. So what I did was run it up to the temp that the temp sensor closes according to the service manual. 88c, it opens at 82c. Well the temp got to 91c and the fan came on
It cooled to 88c and the switch opened and the fan shut off. So I think I'm good.... I did order another temp sensor just to have and according to NMK it will prolly be Chinese garbage electronics.. so... who knows. Now on to fix the tire issue.
Thanks to all that stayed tuned hopefully my crazy event will be of some use to someone
