Just purchased this sxs. Previous owner had gauge issues and replaced it off a model that has a belt sensor. My sxs has no belt sensor. Anyway. It flashes belt across the screen all the time and rpm/speedo gauge goes up and down. Fuel gauge reads properly. Also seems like it wont go over 35 mph and when u give it alot of gas it acts like rev limiter. Could this be due to ecm reading the code from gauges acting like a blown belt? And is there a way i can diagnose this problem. Like will machine run without the gauges plugged in?
