I have a 2011 TRX420 ES 4×4. I went to start it and all I got was a noise comming from somewere under the seat. I figured I had a dead battery (this is the original battery = around 5 years old). I hooked up my charger to the battery and it started up. So I figured I need a new battery and pulled it. I then checked the voltage on the battery and it was 12.3 volts :icon_ nono2:
question is … do I need a new battery or is something else wrong with it?
Note: All the connections were tight and clean.
