Hi all, I’m having an issue with my JD 116H. My battery is 2 months old, I go to start tractor and it turns over but not a constant turning over. I charge battery for 2 hours on low/trickle starts and runs starts and runs for a couple hours. Then nothing my thoughts are it has a parasitic draw, voltage regulator (whatever it uses to re-charge battery) or a bad starter. When it won’t start prior to recharging or jumping I get a reading of 12.1 volts. Any help Is appreciated.
