Will a Bad Solenoid Drain Battery on Lawn Mower | Reply Might Surprise You
If your lawn mower has a bad solenoid, it can definitely drain the battery. The solenoid is responsible for providing power to the starter motor, and if it’s not working properly, the starter won’t get the power it needs to turn over the engine. This can cause some major problems, including a dead battery.
So, if you think your solenoid might be going bad, it’s important to take care of the problem right away. Otherwise, you could end up with a lawn mower that won’t start and a big headache.

What are the Symptoms of a Bad Solenoid on a Riding Lawn Mower?
When your riding lawn mower won’t start, the problem may be a bad solenoid. The solenoid is an electromagnetic switch that controls the flow of electricity to the starter motor. When you turn the key, the solenoid closes, sending electricity to the starter motor which starts the engine.
If the solenoid is bad, it won’t close and electricity can’t reach the starter motor. There are several symptoms of a bad solenoid that you can look for-
1. Clicking sound when you turn the key – This is usually one of the first signs that something is wrong with your solenoid. You’ll hear a clicking noise when you turn the key, but nothing will happen after that. This means that power isn’t reaching the starter motor so it can’t start up your engine.
2. Engine cranks but won’t start – In some cases, you may be able to get your engine to crank over but it just won’t start up all the way. This could be caused by a number of different issues, but a bad solenoid is one possibility. If power isn’t getting through to all of the engine’s cylinders, then it won’t be able to start up properly.
3. Corroded battery terminals – Another symptom of a bad solenoid is corroded battery terminals. Over time, corrosion can build up on these terminals and prevent electricity from flowing freely. This will cause all sorts of starting problems including a clicking noise when you turn the key or an engine that cranks but won’t start up fully.
What Keeps Draining My Lawn Mower Battery?
If your lawn mower battery keeps draining, there are a few things that could be causing the problem. Here are some of the most common reasons-
1. A bad battery – If your battery is old or damaged, it may not be able to hold a charge as well as it used to. This can cause it to drain more quickly than normal.
2. Loose connections – Make sure all the connections on your battery are tight and secure. If they’re loose, they can allow power to leak out, which will cause the battery to drain faster than usual.
3. Corroded terminals – Over time, the terminals on your battery can become corroded. This corrosion can prevent electricity from flowing properly, which will cause your battery to drain more quickly than normal.
4. A charging issue – If you’re not charging your lawn mower battery correctly, it can cause it to drain more quickly than normal. Make sure you’re using the correct charger for your type of battery and that you’re following all manufacturer instructions when charging it.
5. A problem with the mower itself – In some cases, a problem with the lawn mower itself can cause the battery to drain more quickly than normal.
Can a Bad Solenoid Drain Your Battery?
There are a few ways that a bad solenoid can drain your battery. If the solenoid is constantly engaged, it will draw power from the battery even when the engine is off. This can happen if the solenoid is sticking or if there is an electrical short somewhere in the system.
Another way a bad solenoid can drain your battery is by not engaging when it should. This can cause the starter to keep spinning without engaging the flywheel, which will eventually run down the battery.
What Happens When Starter Solenoid Goes Bad?
When a starter solenoid goes bad, it can cause all sorts of problems with your car. The most common symptom is that the car won’t start. The starter solenoid is responsible for sending an electrical signal to the starter motor, which then starts the engine.
If the solenoid is faulty, this signal may not be strong enough to start the engine. Other symptoms of a bad starter solenoid can include-
- The car started and then stalled shortly after. And, 2. The car takes longer than normal to start

Lawn Mower Battery Drains When Not in Use
If your lawn mower battery drains when not in use, there are a few things you can do to try and fix the issue. First, check the battery terminals to make sure they are clean and free of corrosion. If they are dirty, clean them with a wire brush or similar tool.
Next, check the charging system of your mower to ensure it is working properly. Finally, if neither of these solutions works, you may need to replace the battery.
How Do You Test a Lawn Mower for Battery Drain?
It’s that time of year again – time to break out the lawn mower and get your yard in shape for the warmer months. But before you can do that, you need to make sure your lawn mower is in good working order.
Part of that is testing the battery to see if it’s still got a charge. Here’s how to do it-
First, find your battery. It should be located under the hood of your lawn mower, near the back. Once you’ve found it, remove the negative terminal first (this is usually marked with a “-” sign), then the positive terminal (marked with a “+” sign).
Next, use a voltmeter to test the voltage of the battery. If it reads 12 volts or higher, then your battery is still good and you can proceed with using your lawn mower.
However, if it reads below 12 volts, then your battery may be drained and will need to be recharged or replaced before you can use your lawn mower.
To recharge a drained battery, simply hook up a charger (available at most auto parts stores) and let it run until the voltmeter reads 12 volts or higher. Once it reaches that point, you can unhook the charger and proceed with using your lawn mower as usual.
If your battery tests below 12 volts even after being recharged, then it’s likely time for a new one. You can purchase replacement batteries at most auto parts stores or online retailers – just make sure to get one that’s compatible with your model of lawn mower.
Symptoms of Bad Alternator on Riding Lawn Mower
When your riding lawn mower won’t start, the problem may be with the alternator. The alternator is what charges the battery, so if it’s not working properly, the battery will eventually run out of power and the mower won’t start.
There are a few signs that you can look for to see if your alternator is going bad-
1. The engine cranks slowly or not at all – This is usually one of the first signs that something is wrong with the alternator. If it takes longer than usual for the engine to crank when you turn the key, or if it doesn’t crank at all, there’s a good chance that the alternator isn’t working properly.
2. The headlights are dim – Another symptom of a failing alternator is dimming headlights. If you notice that your headlights are noticeably dimmer than they used to be, it’s a good idea to get your alternator checked out.
3. The dashboard lights are flickering – If you notice that your dashboard lights are flickering or going on and off randomly, this could also be a sign of a failing alternator.
4. The battery dies quickly – One of the telltale signs of a bad alternator is a battery that dies quickly or doesn’t hold a charge well.
Symptoms of a Bad Solenoid on Riding Lawn Mower
If your riding lawn mower won’t start, the problem may be the solenoid. The solenoid is an electromechanical device that completes the circuit between the battery and the starter motor when you turn the key. If the solenoid is bad, the engine will not crank.
There are a few symptoms that can indicate a bad solenoid. If you turn the key and nothing happens, or if you hear a clicking noise but the engine does not crank, then the problem is likely with the solenoid.
Another symptom of a faulty solenoid is intermittent starting. If your mower starts sometimes but not others, it’s possible that moisture has gotten into the solenoid and is causing it to fail intermittently.
If you suspect that your riding mower has a bad solenoid, take it to a qualified repair shop for diagnosis and repair. Trying to fix this problem yourself could result in serious injury if you’re not familiar with working on small engines.
