Things You'll Need
Briggs & Stratton solenoid
Briggs & Stratton engines are very common on a variety of machines like generators, mowers and go karts. Over time components of the engine will wear out and you will need to replace them; a common part that will burn up contacts is the solenoid. The solenoid takes electricity from the battery and converts it to the amount needed for the starter on the Briggs & Stratton engine. The solenoid will be mounted on the frame of the machine between the battery and the starter.
Disconnect the red positive battery cable from the battery using the proper sized socket. This will prevent you from being shocked while working on the solenoid.
