Things You'll Need

  • Socket set

  • Ratchet

  • 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.


Step 1

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.

Step 2

Pull the two electrode wires off the solenoid prongs.

Step 3

Unscrew the two wires tightened onto bolts protruding from the solenoid, using the correct sized socket.

Step 4

Unscrew the four bolts that hold the solenoid on to the frame of the machine, using the proper sized socket.


Step 5

Place the new solenoid in the location of the old solenoid and tighten it back on.

Step 6

Tighten the two wires back onto the bolts protruding from the solenoid.

Step 7

Push the two electrode wires back on the prongs on the solenoid.

Step 8

Reconnect the positive battery cable to the battery.
