I have an 02 700 Sportsman than runs great until the headlights are turned on. Shortly afterwards the engine starts to misfire and will stall regardless of throttle input, the digital odometer display also goes haywire. I have replaced the voltage regulator/rectifier located above the radiator as well as the two 20 amp circuit breakers located in black pouches. The battery is less than 2 years old and voltage remains around 14.5 when the misfire starts to happen.
Any help is appreciated, thanks.
