My 6 year old battery was on it's last leg, and I decided to jump it with my car battery. It started up right away, and I cut my 3 acres of lawn. After I finished I tried putting the battery on a Battery Charger and Maintainer, but to spite charging it my battery would not hold a charge. So today I went and bought a new battery, and even thought the lights shines bright within my hour glass tell my my battery is okay and getting juice, but when I turn on the switch to start it, I hear nothing not a single sound at all. Not even a click. Could by charging it by way of my car battery caused the solenoid to go bad?
