I just bought a 2000 Foreman 400 and the speedometer is not working and the odometer does not work, but the hour meter still works. Does any body have any ideal what the problem could be and how to go about checking it? Maybe the speed sensor? Also, there is a tiny green light, located above the hour meter, that blinks on and off. Is it supposed to do this, and what does it mean? It doesn't have a digital dash. Any help would be greatly appreciated. Thanks.
