I recently put a new electric clutch on my mower and have started it twice with no issue. However, the third time it wouldn't even turn over. I knew the battery needed replaced, being nine years old, so I put a new one in it, after bringing it to a full charge. It still wouldn't turn over and was making a rapid clicking sound when attempting to start it that sounded like a starter engagement gear that is too worn to actually catch and rotate the flywheel. I took the starter to a re-build shop in Hilo, they tested it, inspected the brushes, and told me there was nothing wrong with the starter. I re-installed it and the mower did the same thing. This time, I put my hand on the starter solenoid as the rapid clicking was going on and discovered the clicking was coming from the solenoid. I went back to town, got a new one, put it in, and the thing is still not starting, just making that rapid clicking noise from the new solenoid. At this point, I'm out of ideas. Can anyone give me some experienced ideas as to where to go from here?
