When the fourwheeler is cold the oil light and the fan are on. I went and unplugged the thermister and nothing happened. Then I unplugged the fan with the thermister plugged in the light and fan are off. I am thinking that the thermister switch is bad. I am at a stand still right now. Any opinions are welcome.

 

are you sure they aren't supposed to do that? do they turn off after you start the quad, because my z400 does that, when i just turn the key on, the high temp light comes on, and once it is started it goes off, also my blaster did that.

 

The light and fan stay on while running when the quad is cold. That is not supposed to happen.
