I am going crazy trying to figure this one out. Recently snorkeled 700efi is overheating but I am inclined to think that the problem is not related to the snorkeling. My fan is no longer coming on. I checked the fuse and also the diode marked fan in the fuse box and found both to be OK. I checked the fan to make sure that it is working under normal conditions so I powered it directly from a battery and it works fine. I checked the continuity of the sensor and it works as well. Hooking a positive from an outside battery source to it. Once the temp got high enough the fan came on. I downloaded the wiring diagram from the forum and it indicates a diode in-line with the ground. Does anyone have experience with this?
I have a 2001 sportsman 400 that overheats. I do not hear fan kick on, however fan does work if i put 12 volts to it. Does anybody have any ideas as to what the problem may be>? I know there is a water pump and it looks like 2 sensors that may be wired to fan motor to turn it on. Any help would be appreciated. Thanks, boogs
2003 Yamaha Warrior 350 Overheat and Gas/Air Mix Problems. My Warrior seems to be overheating on me. I live in Metropolitan Arizona, and I expect to have some issues with heat ,but not this bad. After about 30-40 minutes of riding it wants to die on me, the only thing to do to keep it from dieing is keep it revved up at idle and between gears. Tell me what you think about that issue. The next issue is that my Gas/Air mixture might be off. I don't know which screw is the mixture screw, I know which one is the idle screw. And I do know thats it all the way in 2.5 turns out on the mixture. It needs a new throttle cable and will come eventually. I'm just trying to fix these two issues for now. And last issue, but I think its more so related to the gas/air mixture. I takes FOREVER to start my quad. At least 10 minutes. I know its not getting enough air (or too much gas) because I had to take three of the screws out of the air filter cabin to get more air into the carburetor. When the air filter cabin lid is screwed down with all 5 screws it takes forever to start Full choke, about 10-15 minutes, and 50-75 cranks (tallying an almost dead battery), but when its propped open with a tire plug tool, it doesn't take AS long. Full choke, about 3 minutes and 25-35 cranks later! From my understanding a finely tuned ATV should only take a minimum of 2-10 cranks to start on full choke. Could there be some other issues with my carburetor besides the gas/air mixture being off? Like like the float or the jets? Please, any help will be greatly appreciated. Nathan L. Mesa, AZ
