Most modern riding lawn mowers are equipped with electric starting systems. These electric starting mechanisms offer great convenience over older methods. By older methods, we mean blowing your arm muscles out ripping the cord to get the mower started.
Several essential parts play a part in the working of electric starting systems. One such part is the solenoid. If you have a faulty solenoid your mower won't start.
A solenoid is a low-amp relay system that bridges the high-amperage electrical connection between the battery and the starter motor when you turn the ignition key to start the mower.
A defective solenoid denies electric charge to the starter motor thus preventing the mower from starting up.
A solenoid is basically an electromagnetic switch that needs to work for your mower to start. In all regards, the solenoid is the main component between the ignition and the starter, without a functional solenoid, the key starting mechanism would fail to initiate on a riding lawnmower.
Here are a few simple steps that you should know to check if the solenoid of your mower has gone bad.
Step 1 – If the riding mower's starter motor does not move or is unresponsive when you turn the ignition key, you need to test the solenoid.
Step 2 – If you are unaware the solenoid is a small black box that is directly connected to the battery of your mower via a thick red wire. If you are having trouble locating the solenoid just look for the thick red wire from the battery and trace it back to the solenoid.
Step 3 – There are two posts on a solenoid. The red wire is attached to one of the posts, and right next to that post, a wire is leading towards the starter motor. These posts will be directly in line.
Step 4 – Close the gap between the posts with an insulated screwdriver. If after doing so the starter motor spins when you make contact it is an indication that the solenoid of your mower is defective. And if the starter motor does not spin then you might have a problem with the starter.
Other things that you should also check if you are having issues staring your mower are:
1 – Check the battery charge level of your mower. If the charge is below 12.5 volts you might need to charge the battery before starting the mower.
2- Check all the visible electrical wiring connecting the battery, solenoid, and starter motor to make sure that they are tight and free of corrosion.
3 – If you find any corroded parts clean them off.
Maintenance is important for your riding lawn mower to ensure that it lives up to and exceeds its life span. It is important to know the basics of how to take care of your machine.
