My 2008 Kioti CK30 wouldn't' start a few weeks ago and I thought it was the ignition/ key switch as I have had issues with it in the past so I ordered a new one. While waiting for it to come in I took apart the old one and cleaned it up to have as a spare. When the new switch came in yesterday I installed it and the tractor would not crank. Lights on the panel wouldn't even come on, same as with the old switch. I then hooked up jumper cables to the tractor battery thinking it was a dead battery. While hooked up, the gauges will come on but when I turn the key to start, it just clicks. Thinking it was a very dead battery I took it to a auto parts store and had it load tested. Nothing wrong with the battery. I even swapped out my battery for another one in another tractor and it starts right up so I know the battery isn't the issue. Where should I look next? What would cause the tractor to have the gauges come on when hooked up to jumper cables but not crank. Any help is appreciated. Thanks
