Keeping that in mind, this section carries the Toro zero turn mower electrical issues along with their remedies.

So, why don’t you check them out?

Problem 1: Battery with Faults

One of the noteworthy problems is the battery with faults. First, it can have irregular connections due to loose wires.

Second, the battery can be filled with uncleaned dirt and debris. Finally, the battery is not taking charge in or holding it for an average period.

Solution: Readjust Battery Connections or Replace it

To fix the battery issues, readjust its connections by going through the wires. Then, check its chamber and clean with a silicone brush or dry cloth. If charging errors are detected, replace the battery.

Problem 2: Disconnected Spark Plug

A disconnected spark plug is always a barricade for the Toro zero turn mower.

It gets disconnected when dirt and debris starts living with it and corrosion comes gradually. In some cases, the connection of it gets loosened and no spark can go from it.

Solution: Clean and Connect the Spark Plug Wires

As dirt is concerned in this regard, you shouldn’t delay in cleaning the spark plug. After that, check all its connections and set the wires again to secure them.

Problem 3: Bad Starter Solenoid

A bad starter solenoid is a barrier that doesn’t help the starter motor to start the Toro zero turn mower.

The solenoid gets bad when its wires become unworkable. As time flies, weakness starts living on them and sometimes, they are burnt due to the overheating solenoid.

Solution: Inspect the Wires or Install New Ones

Before you think that the starter solenoid is bad, I prefer inspecting the wires connected to it. If they are already burnt or weak, nothing is more efficient than installing new ones. 

Problem 4: Hour Meter Not Working

An hour meter is an important electric part of a Toro zero turn mower. But, its terminals are very common for different issues.

Because after a period, you will encounter them with corrosion all over their body. In some cases, they get misplaced from their position and thus, the hour meter also faces troubles.

Solution: Clean the Terminals, Adjust or Change Them

First, go with cleaning them thoroughly and make sure to turn off the mower. Then, adjust the terminals and observe their connectivity. If nothing is changed, change the terminals.

Problem 5: Defective Ignition Switch

A defective ignition switch refers to zero ignition of the Toro zero turn mower when the key is inserted.

Well, it is noticed when the ignition switch loses its connection with the electric unit. The wires of it can cause it, too, as they can get bent or corroded.

Solution: Secure Switch Connections or Replace it

To get the ignition switch back on duty, secure its connections. To do it, clean the wires and inspect them on both sides connected to the switch and electric unit. Replacing the switch is essential when nothing makes a change.

How Do I Know if My Toro Zero Turn Battery is Bad?

Answer: The sign of a bad battery on a Toro zero turn mower is the charge in it won’t stay even for the average duration. While charging, it may take more and more time or refuse to take charge.

What Charges the Battery on a Toro Zero Turn Mower?

Answer: The battery on a Toro zero turn mower is charged by the alternator. Though it powers up the mower, it leads the battery to be charged by offering voltage.

End Words

In short, Toro zero turn mower electrical problems are those that can leave the mower not working at all. Because the mower components are directly or indirectly connected to the electric unit.

For this reason, make no delay when you suspect the electrical parts are creating barriers. And, get into troubleshooting them carefully.
