my 02 prairie 650 is flashing 2wd 4wd, i changed the 3 fuses underneath the seat and that didnt fix the problem. what else is there to check or do. i really need to get this working, it snowed alot here.

 

A quick flashing 2wd/4wd lights mean there is a problem with the 4wd actuator --- 1/2 second interval

A slow flashing 2wd/4wd lights mean there is a problem with the EBC (engine brake control) --- 1 second interval

A 2 second interval indicates both actuators are malfunctioning.

But before you get too involved in fixing the ebc or actuator... make sure all the fuses are good and have a good connection.
From my experience, this is where most problems are found, the fuse box contacts will corrode over time and give you problems.

hope this helps
