Yesterday I was out riding and after about an hour my oil light was blinking I pulled over and checked the oil and it was full, I rode it a short distants to the gas station and washed it and gased up and rode it home, the light did not come back on after I washed it! Its a 2004 700 prairie, it has 1500kms on it, I just changed the oil with 5w30, it was about -5C yesterday. Why did the light come on? Should I be concerned, should I have it checked out, I still have lots of warranty left, it has never done this before.

 

I wouldn't be riding too much before I check into further. If possible, measure the oil pressure when the oil light is on. It should be around 70 psi when the engine is warmed up. To do that, remove the oil pressure switch on the left side of the engine and hook up the oil pressure gauge/adapter. If you can't do that, just open up the valve cover of the front cylinder and see if any oil is splashing/flowing.

 

Just a thought but with the temperature that low the oil could have become very thick and heavy making it hard for the oil pump to pick up and supply enough pressure. That would also explain why the oil light never came back on once the motor got hot and helped to thin down the oil.

 

The motor was totallly warm, had been riding in the snow for at least an hour, I am bringing it in today for the recall work, the oil light never came on again, should I still have it looked into.

 

Absolutely have it checked out. Even if it's a bad connection going to the light I would have it fixed. After all if you ignore the oil light because it has a short then you could cost yourself big bucks if something does happen to go wrong inside the motor.

 

Just dropped of the prairie at the dealership, they found the problem as soon as I had it of the truck. I was the little blue wire that is connected to the oil pressure sensor, thanks everyone for your input. Jason
