I have a 2016 Defender HD10 purchased new. It is very lightly used…typically only started once a week and run for ten minutes. Recently, after a short ten minute ride and shutting if off for ten minutes it would not restart. I had to haul it home.
Typical voltage before ride 12.55, after ride 12.38. This morning with engine running it goes up to 14.67 after shutting off 12.93.
I’m hoping someone might have some ideas. I’m thinking maybe I should replace the battery.
