My father-in-law has a 2009 JD Z860A zero turn and is having issues with starting it. This all started last year when he was installing a new battery in it and the colored protective caps on the battery leads were reversed. This led him to installing the battery backwards and attempting to start it. I believe that he heard a grinding noise when he tried to start it and released the key immediately. After this happened when he tries to start it cranks but will not turn over on its own. He has only been able to start it by "jumping" the mower with his tractor. Once it's started he has no problem running it at all until he tries to start it again. He has confirmed that the battery is not the issue and is fully charged. He's wondering if there could be a fusible link that might be partially broken and will only work when there is extra "juice" running through it. Note that this mower has extremely low hours on it for its age, maybe a couple hundred.
Thank you for your help!
