I have a 2014 Sportsman 570 EPS with only 380 miles. I bought it used, and the owner had put in a new battery (purchased quad with only 150 miles). I also have a battery tender. I went riding in West Virginia for 3 days, and on the last day, my power steering went out. My console said "LOW" and it appears that the battery was low (even though I was riding..seemed it wasn’t charging). I rode without Power Steering for a while and then we stopped for a quick break. Once we stopped, I couldn’t start my quad. We had to jump it, we got it started, and I continued rididing without Power Steering, then it came back on. It was on for a bit, then it again went out and the console said "LOW". I continued to ride without Power Steering and then it again came back on. I finally got home, and I hooked it up to the tender and had a meter on it. It pretty consistantly reads about 10.5v-11v when just sitting, when I start it and idle it up to about 3000RPM, it reads around 14. So I unplugged the tender, let it sit a few weeks, and went to start it and had nothing. I unplugged the meter, plugged the tender back in and let it go a few days, and was able to start it, but it barely turned over. Drove it around the block and into the garage….hooked up the meter with bike off and read 10.5-11v, started it (had to turn lights off) and once started, read around 14v when at 3000 RPM. I have no idea what might be going on…is it a bad battery or something wrong with the bike?
