How does a lawn tractor starter solenoid work?


Small magnetic component placed within the beginning motor, the starter solenoid serves to activate the starter motor. When you turn the ignition key to the “start” position, the battery transmits a little electrical charge to the starting solenoid, which in turn activates the starter mechanism. It is the solenoid that shuts the switch, which results in an increased quantity of electricity being sent to the starting motor.


People often inquire as to how they can tell if the solenoid on their lawn mower’s starting is faulty.

To begin, turn the ignition key to the “On” position on the dash. Look for the huge terminal posts on the solenoid where the thick red wires are connected to the solenoid, which should be easy to see. Using a screwdriver with a metal shaft, connect the metal shaft to both of the big terminals at the same time. If the engine turns over and starts, this indicates that the solenoid has failed and should be replaced.

As a result, the concern is whether a malfunctioning solenoid on a lawn mower would deplete the battery. There is almost no way for a solenoid to exhaust the battery’s capacity. Nothing more than connecting the battery cable to the starting cable is accomplished by using this device. It’s possible that you just have a defective battery. Lawn mower batteries are rarely used for more than two years at a time.

In a similar vein, how does one go about testing a starting solenoid on a Briggs & Stratton engine?

Instructions on How to Check a Solenoid on a Briggs and Stratton Engine

Place the engine on a firm, level surface to prevent it from slipping. To identify the solenoid on the engine, follow the positive (red) line that comes from the battery; it will eventually bring you to the solenoid itself.

Take the spark plug wire out of the spark plug and set it aside.

Maintain the connection between the negative lead of the voltmeter and the negative battery post.


How do you put a lawn tractor starter through its paces?

The jumper wire should be connected to the positive terminal of the battery at one end, and with its other end it should be touched to a little lug marked S on the engine starting solenoid in order to test the starter ignition switch. Whenever the engine starting motor goes on or runs, this indicates a problem with the starter ignition switch, which has to be repaired or replaced.

What is the best way to bypass a solenoid?

Bypassing the Starter Solenoid is a simple procedure. Locate the starting motor, which is located below the car. Locate the two metal connections on the rear of the starting solenoid that are marked with an arrow. Place the metal blade of an insulated screwdriver against the metal contacts on both sides of the screwdriver. Get a buddy to assist you in starting the car by turning the key in the ignition. Keep an ear out for the starting motor.


When I attempt to start my riding mower, it makes a clicking sound. What is the cause of this?

When the key is turned to the start position on the riding mower, a strong clicking or fast clattering sound may be heard. This indicates that the battery or a component of the starting circuit is malfunctioning. The clicking sound is produced by a component known as the starting solenoid. Low battery voltage indicates that the battery needs to be recharged or replaced.


What may be causing a riding lawn mower to not start?

If your riding lawn mower won’t start, there are a variety of possible causes, ranging from faulty gas or a dead battery to a faulty starting motor or an improperly installed ignition coil. Possible causes include a dead battery, faulty starting solenoid, a failure of the beginning motor, or a stuck engine.


What is causing my John Deere mower to not start?

The spark plug is responsible for igniting the air mixture and gasoline in the engine’s cylinder, which allows the tractor to start. The last issue that might arise is a blocked fuel filter. This may also occur as a result of contaminated or unclean gas. Remove the old gasoline from your tank and replace it with fresh fuel before changing any of these components.


What is the best way to start a lawn mower using a screwdriver?

Starting the lawnmower with a screwdriver is one option. Instead of using jumper wires, a screwdriver may be used as a bridge mechanism. If the gap between the two electrical posts to engage, the solenoid and the starter, are extremely near to one another, the screwdriver may be used as a bridge to connect the two electrical posts to engage. In place of the key, a flat-head screwdriver may be used.


What is the location of the solenoid on a Craftsman riding mower?

Locate the solenoid by looking along the mower’s frame or towards the rear of the engine compartment. Typically, the solenoid is a cylindrical or square palm-sized black device that is mounted to the mower frame near the engine or to the rear of the engine compartment near the battery on most brands of lawnmower or riding mower.


What wires connect to the starting solenoid and how do they get there?

As seen in the illustration, the conventional starting solenoid has one tiny connection for the starter control wire (the white connector) and two big terminals: one for the positive battery cable and another for the thick wire that powers the starter motor itself (the black wire in the photo) (see the diagram below).
