I have an 09 800, has about 9000 miles on it. Last nite on a ride after dark I notced that my lights would dim a bit and my engine would also miss and sputter, almost like running on one cylinder, after a short time it would return to normal but it did that several times. I have a new battery, the rzr does have a radio and 2 other additional headlights. Could this maybe be a voltage regulator problem? Any help would be appreciated.
