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.
Pull the two electrode wires off the solenoid prongs.
Unscrew the two wires tightened onto bolts protruding from the solenoid, using the correct sized socket.
Unscrew the four bolts that hold the solenoid on to the frame of the machine, using the proper sized socket.
Place the new solenoid in the location of the old solenoid and tighten it back on.
Tighten the two wires back onto the bolts protruding from the solenoid.
Push the two electrode wires back on the prongs on the solenoid.
Reconnect the positive battery cable to the battery.
