Clicks Coming From Toro Lawn Mower But Won’t Start

If you try to start your mower, all you hear is a clicking or humming noise, it may be broken. So that you can finish mowing the lawn, let’s look into the potential causes of this problem.

When the wiring and cables on a Toro lawn mower are frayed or corroded, when the battery is weak, when the ground is bad, when the beginning solenoid is defective, or when the starter motor has failed, the mower will make a clicking sound and refuse to turn over.

Make sure you’re protected by donning the proper safety gear. If you don’t feel confident working on the electrical system, it’s probably best to call in a pro mechanic.

Before doing any electrical maintenance or repairs, remember to first detach the negative (black) connection from the battery.

Reasons Your Toro Mower Just Keep Clicking

Battery, wiring, and terminal damage on a Toro lawn mower

Inspection of the wiring and cables should be the first step. The solenoid must be connected to the starter motor, and the battery must be connected to the solenoid.

You should inspect the terminals and parts for signs of corrosion. If corrosion is discovered, it must be treated.

Any frayed or broken wires or cables should be fixed immediately. If your Toro mower is having trouble starting, check the cords.

For cleaning purposes, disconnect the battery and take apart the mower’s corroded parts.

An effective combination is a wire brush and a solution of baking soda and water (2 cups of water + 3 heaping tablespoons of baking soda). To fix or replace corroded wiring, just do it.

The terminals and wiring will be protected against corrosion if a dielectric grease is applied to them. In the event that terminals are broken or otherwise compromised, new ones must be installed.

What to Do If Your Toro Lawn Mower’s Battery Is Dead or Weak

It’s possible that your Toro won’t start if the battery isn’t fully charged and has lost some of its power.

The battery voltage should be checked. If the battery is low, put it on a battery charger. You know the battery is faulty and needs to be replaced when it stops holding a charge.

If you are able to recharge the battery, but it still dies, the Toro’s charging system may need to be inspected. For details on the power delivery system, read on.

How to test the battery on a Toro lawn mower

Connect the red and black probes of your multimeter to the corresponding connections. The majority of Toro lawn mowers use 12-volt batteries.

The voltage of a 12-volt battery can range from 11.50 to 12.70. A fully charged battery will read around 12.7V, whereas an almost dead battery will report closer to 11.5V.

Power up a Toro mower

• Protect your eyes and skin from acid and electricity by donning the proper protective gear.
• Locate the battery’s terminals and gain access to them. In order to access the battery or battery compartment, you may require the screwdriver to remove the cover of the lawnmower.
• Don’t remove the battery from its case just yet; the terminal cables will stay connected.
• The positive (red) charging cable should be attached to the terminal first, followed by the negative (black) terminal.
• Keep the rubberized charging cords and clamps from making direct contact with your skin.
• Alter the charger’s settings to the desired voltage and amps. A lawnmower’s voltage is typically around 12 volts. Increasing the current speeds up the battery’s charging process. The recommended starting point is 2 amps, with a maximum of 10 amps.
• Keep the charger plugged in until the battery gauge indicates it is fully charged.

To solve the problem of a low Toro battery, simply connect it to a battery charger. It’s time to get a new battery if you notice that the old one won’t retain a charge.

You should check the charging mechanism if the battery may be fully charged with a battery charger yet you keep finding it dead when you attempt to use your Toro.

Toro lawnmower failure due to poor soil

The black ground connection connecting the Toro’s battery to the frame should be inspected. It ought to be corrosion-free and have good contact qualities.

Verify the solenoid’s ground connection as well. When it comes to grounding, a 3-post solenoid takes care of itself.

REMEDY: Swap out the frayed grounding wire. If there is rust on the battery or starter solenoid’s grounds, clean it off.

Ineffective Toro Lawnmower Starter Solenoid

The clicking noise coming from your mower is probably due to a faulty starter solenoid. Simply put, the solenoid is a mechanical switch. When activated, this magnetic switch connects power to the starter motor, allowing the engine to turn over.

The solenoids typically control the starter are attached to the starter. They needn’t be, though, for the concept to function. Locate the solenoid by using the positive battery cable.

A faulty Toro starter solenoid could be the result of a number of different issues. Either the copper plate or the internal spring can corrode and grow weak over time.

The failure of the starter solenoid might also be caused by a poor ground, a weak starter, or a weak battery.

In other words, you need to check the solenoid that controls the starter. Wrenches, a screwdriver, a continuity lamp, and a volt-ohms meter will all come in handy.

Read: “How to Tell Your Lawn Mower Solenoid is Bad” and implement the steps it suggests. Bypassing the solenoid to start the mower indicates that it needs to be replaced.

Toro Lawnmower Faulty Starter Motor

It could be your starter if you’ve already ruled out the battery, cables, wiring, ground, and starter solenoid and are still having trouble starting the engine. It is possible to remove the starter and put it through its paces.

It’s common knowledge that a lawnmower’s starter is one of its most expensive parts. Before you go out and buy a new starter motor, it’s a good idea to get the diagnosis from your local dealership.

A local repair company that focuses on starter and alternator repairs is another option. The service center staff can inspect the starter and possibly rebuild it.

The Toro’s Battery Drains Due to a Faulty Charging System.

If your Toro mower has a faulty charging system, your battery won’t stay charged, and you won’t be able to start the mower.

Using a volt-ohm meter, verify that the charging mechanism is functioning as instructed.

If your Toro lawnmower’s battery isn’t being charged, it’s best to have a mechanic who is knowledgeable with your charging system check it out and make any necessary repairs.

It can be challenging to isolate the root cause of charging system problems.

You’ll probably just be tossing components at your mower if you don’t know the charging system.

Very high costs are possible since electrical components cannot be returned if they are installed incorrectly. A faulty stator or alternator, a malfunctioning regulator, or some other electrical issue could be to blame.
