Took my sled and after 20 mins the battery light starts flickering and then the sled dies. Started it back up everything was fine until I gave it gas and once it got over 2,500 rpm the light battery light comes back on the the sled shuts off. Tried to pull start it and same thing. So got it towed to the trailer then once home put the battery on the charger for 24 hrs. Took the sled back out the next day and the exact same issue. The falling day went out and bought a new battery. Sled started up fine no issues so went out riding for about 45 mins when the battery light came back on and the sled shut off. After that I checked every fuse and and wiring connections and it was all fine. Any suggestions what this could be?
