  1. Does anyone know what the sensor or switch is called inline from battery to the starter. Not sure what is activated. The starter will soon when testing. The start button works. If I bypass the sensor I'm sure it will work. It's a 2014 Craftsman 22" all wheel drive electric start.

  2. Is that a 110V power source or a 12V Battery source and how does one tell if it has that particular electrical connection at the starter
    I ask because it's the first time I ever saw a push mower w/an electric starter that small nor a connection like that either ,so I'm kinda dumbfounded at this point

    God bless and have a cool day .

  3. How do you know if you need to change the starter I turn the key on mine but it doesn’t do anything at all you don’t hear nothing
