I have a Kobalt KSPM 2040A-03 40 VOLT MOWER. It is just 3 months old. The self propelled works fine. When i try to start the the motor I can hear a click like a relay engaging but the motor does not start. The third green lite flashes indicating overload. I fully charged the battery and let the mower cool off for 24 hours cleaned the underneath still will not start. The blade is easy to turn by hand. Tried to return it to Lowes they said that I had to send it back to Kobalt because It was more than 30 days since I bought it BS. Don't know what to do or try next. Please Help if Possible Thanks Mike
