Hello, my GT sat out in the elements for about 3 weeks (did start and run it several times during this) but we had a heavy rain and now when I attempt to start it there is a loud whining whirring noise but the engine will not crank. It has been a little slow to start over the past 3 months or so. The battery says 12.4v and I only have 46 hrs on the machine. DOM 11/2016 has a 26HP Kohler. I am looking for ideas, COVID has made getting a hold of a service person a near impossible task.
