Last weekend my visiting son took my 41 9N for a quick trip around the property. He parked it for the night. In the morning the battery was dead. I pulled the battery and charged it, next morning it was dead again. When I removed it again, I checked between the disconnected battery cables with a volt meter and had a dead short. I see nothing obvious. Before I start diving into this, I was hoping that someone may have had this issue in the past and could point me in a direction to start. Thanks in advance.
