My "06 Swithback 600 started acting up today. Headlight would wink very dim and then come on bright. Then it would wink dim again. The digital display would also go blank with the oil light blinking eratically. The display would act up when the sled was given full throttle. In addition, I'd loose about 600 rpm when the display would wink out. As if the failsafe temp protection activated. Anybody got a clue? Also, the sled ran fine three weeks ago. Since then I installed a new tank and carb spigots. I'll be digging into it tomorrow in search of a pinch wire or bad connection. The dimming headlights have me thinking it's a VR issue.
