Was there a recall or is it just a common problem?

We just bought a 2003 Trail Boss that might have 10 hrs on it. It's never even seen dirt. As soon as you turn the key on the fan comes on and the oil light stays on. I can disconnect the sensor and both the oil light and fan will go off. I don't think it would cause any problems leaving it disconnected, but I would rather it work correctly.

The foot brake does not work either. No problem as long as the lever brakes work (they do).

Also, have there been any recalls for this model?

 

does the oil light stay on when you start the bike? check to make sure the sensor wire is plugged in that controls the fan. like a temp sensor, im guessing if its unhooked it will cause the fanto run all the time. just idear.

 

Yes, the oil light continues to stay on while running, and so does the fan if you leave the wires connected. If you unplug the fan connector, which includes the oil sensor, the oil light and fan will quit. I'm sure I could run it like that with no problems at all, unless we were to get it into some type of bind and run the engine hot. I'll replace the sensor if needed. I just thought since I've seen so many other people have the same problem that it might be a recall? Didn't find anything about it by googling though.

 

the recall was the loose clamps for the oil lines at the radiator....sounds like you have a bad switch somewhere....

 

bad sensor

 

Surely someone here has ran into this problem before and had it repaired? I found several posts by searching with members having the same problem, but nobody has ever posted a remedy?

 

just pm the people who posted it for that bike and hopefully they will tell you how they fixed it. im guessing but if the bike is cold and theres plenty of oil in it and there both coming on and connected to each other then i agree it much be a sensor issue.

 

Theres a thermister that screws into the oil cooler.Replace it and you should be good to go. Part # is 4010274. Let me know if you need any more help.

 

How would I go about checking it to make sure that is the problem and not the ECM box? I'd hate to purchase a $70 part and it not work. I have already check for continuity (shorted), and it is not.

 

Since its a thermister, I dont think it would read short to start the fan. I do think the resisitance would change as it heats up but im not 100% sure. Take a resistance measurement across the 2 wires while cold and let me know what you find and Ill do the same on mine. If you want to start the bike and let it heat up and take another reading you would be able to tell if there was any change.
