Hi, I have an OLD 60" turf tracer hydro. I have an intermittent problem with starting on hot days. It has a 22 hp Kohler replacement engine, but did the same thing with the original 20 hp Kohler. Here's a description. On hot days. Morning start up, no problem. Mow three or four lawns starting no problem. Go to start mower after it is good and hot. Problem. I turn the key and here a single click that I have traced to a conjunction on the driver's left side of the mower. It has the positive from the battery cable going to it and the hot wire going to the starter. Sometimes if I keep on trying,after several of the single attempts and subsequent clicks it will sometimes start. It seems like the current is never making it to the starter? If it doesn't start after some of those attempts, it will start no problem when it has cooled. I have checked all of the battery connections and checked for corrosion. The battery is less than 2 weeks old. The problem was there before the new battery as well. Any ideas?
