SOLENOID 1722739SM

This is an original part from Simplicity for use with Lawn Tractors. The solenoid is a high-current switch that sends power to the starter motor to spin the engine when you turn the ignition key to the start position. The control coil at the bottom of the starter solenoid closes a contact between the top solenoid posts to send current to the starter motor when the bottom control coil gets power from the ignition switch. The most common reason for replacing the solenoid is when the engine will not start or even turn over, and the battery is not dead. This part is sold individually. The tools that you will need to replace the solenoid are two 7/16" wrenches and a 3/8" socket.
