I have a snapper lt160h42cbv was mowing and it suddenly disengaged the blades i drove it back to garage cut it off but something on the motor did not cut off sounded like it was still running but the engine was off so i unhooked the battery and it stopped. noticed the belt was broke so i replayced it when i went to hook back the battery cable it spaked and sounded like it tried to start got the cable on it then went sto start it and it does nothing i can hear a click in the engine when you turn the key but does not even try to start like battery was dead i checked the battery and its fine with 12V on meter also checked the fuse it looks fine. Dont know what else to do.
