I have a 2006 500 HO Sportsman. I noticed that the reverse/ speed override button wasn't working and that our old speedometer was reading the wrong RPM. So I've replaced the Speedometer with a new one. However, I'm getting some readings but not all of them. The reverse/ speed override button is still not working or letting me select any of the other modes: Tack, Trip, Odo. Currently also not getting any reading on the speed of the bike. The 4x4 button turns on and I have power to the speedo but no speed reading. Haven't checked the wires yet with my meter but I did pull and clean the ends to the switch on the handle bar. That didn't change anything. The low battery light flashed once while on the test drive but I had also installed and played with a new LED bar, which could be the reason for the low batt.

Suggestions? Anyway this could be the rectifier?
