When I start my 2005 sportsman 500 the rpms do not work they stay at 0, when you put it gear and start driving it will begin working when you get to about 30-45 mph. If the rpms aren’t working for a while the battery light will begin blinking. If you go to use the winch the winch will just click. If anyone has any ideas please let me know. Already replaced the ECM under warranty and it has a brand new battery and CDI.
