When your lawnmower won’t start and the engine won’t turn over, start by locating and examining any components that could be preventing the starter motor from receiving electricity.
If the battery is weak, the wiring and parts are rusted or loose, the fuse is blown, the ignition switch is broken, the safety switch is broken, the starter solenoid is broken, or the beginning motor is broken, the Snapper lawn mower won’t start or crank.
Remove the battery’s black negative cable before performing any electrical system repairs. Prevent injuries by exercising caution. Your Snapper operator’s manual has a list of hazards and safety measures.

The Cause Of Your Snapper Mower Not Starting
A Snapper Battery That Is Dead Or Defective
Your Snapper’s battery won’t supply enough power to start the engine if it is weak.
Maintaining a battery at full charge will help it last longer. hen keeping the lawnmower in storage batteries, this is crucial. If a battery is not fully charged and is kept in a cold environment, the battery may freeze and become damaged.
Follow the instructions in the article “5 Things That Are Draining the Life of Your Lawn Mower Battery” to test your battery.
Battery Charging: To charge your 12-volt battery, use a battery charger. Wear safety equipment to prevent electrical shock to your eyes and skin before continuing. To use a charger to charge the battery in your lawn mower, follow these steps:
- The battery and connections are accessible. The battery may need to be uncovered using a screwdriver. Don’t take the battery out of the case.
- Start by plugging in the positive cable on the charging cables. This is the red cable, often known as the plus sign cable. Connect the cable to the battery’s positive terminal.
- Connect the negative cable to the battery’s negative connector. This is the cable that is either black or has a negative indication.
- To avoid electrocution, ever handle anything that is not covered in rubber.
- Voltage and amperage levels on the charger can be adjusted to the desired values. Batteries for lawn mowers typically have a voltage of 12 volts. A higher amperage charges the battery more quickly. Work your way up to no more than 10 amps after starting with two camps. It’s best to charge slowly.
If the battery is unable to maintain a charge, a replacement battery must be purchased. A new battery can be purchased at your local hardware shop, car dealership, or lawn mower dealership.
Bring over your old batteries. The majority of establishments will levy a core fee to you if you don’t give them your used battery.
Your Snapper May Have Loose Or Connections Or Wires
The vibration of the Snapper mower might cause the wiring and electrical components to come loose. Verify that these components are in good condition and that they are attached securely.
Check the components for corrosion accumulation caused by moisture. Corrosion must be eliminated since it can damage continuity.
Remove the battery cables first, then clean the parts. Next, use a wire brush and a solution of baking soda to remove the corrosion (2 cups water to 3 heaping tablespoons of baking soda).
If you are unable to clean the terminals or other components, replace them.
Your Snapper Lawn Mower’s Fuse Is Bad
Your Snapper’s electrical system is guarded by a fuse against threats like a short or a power surge.
To be sure you don’t have a blown fuse, inspect your mower. If you’re unsure whether the fuse is blown, you can test resistance by placing a multimeter probe on each of the fuse’s prongs.
Your fuse is in good shape if the resistance reading is close to 0. A faulty fuse is indicated by a resistance value of infinity.
In place of a blown fuse, use one that has similar amperage to the new fuse. Bring your Snapper to your local lawn mower dealer or lawn mower repair facility to investigate the issue if you keep blowing fuses.
Your Snapper Lawn Mower’s Ignition Switch May Be Defective
If you turn the ignition key while inserting the key and nothing happens, the ignition key switch may be to blame. Your Snapper won’t be able to start or turn over.
To find out if the ignition switch is the issue, use a multimeter to test the switch’s continuity. To do this, check for the prongs marked S for the starter solenoid and B for the battery.
Turn the key to the start position after inserting it. he B prong with one probe, then the other to the S prong of the multimeter when it is set to measure resistance.
The resistance of a reliable switch for the ignition will be close to zero ohms. The ignition key switch has to be replaced if it measures infinite resistance.
Your Snapper Lawn Mower Has A Faulty Safety Switch
In order to keep you safe, your Snapper has a mechanism installed to control operator presence. If a safety switch is broken, your Snapper could not turn over.
Utilize a multimeter to test your switch. To identify a broken switch, you can also momentarily ignore the security switch, but solely for troubleshooting purposes.
Mowers should never be operated without the safety switch.
Never operate a lawnmower with a safety switch turned off. You can avoid major injuries by using a safety switch, and you never know when you’ll need one.
Your Snapper Lawn Mower Has A Bad Starter Solenoid
An electromagnetic switch called a starter solenoid activates the starter motor, which starts the engine of your Snapper lawn mower.
When the spring loses strength or the copper plate starts to corrode, the starter solenoid may malfunction. The solenoid may malfunction as a result of a poor battery, weak starter, or poor ground.
You need a fully charged battery before you can test your starter solenoid. Utilizing the procedures outlined in “How to Tell Your Lawn Mower Solenoid is Defective” to identify a bad starter solenoid, continue testing the solenoid.
Your Snapper Lawn Mower Has A Bad Starter Motor
It’s time to consider the starter after ruling out the battery, cables, wiring, ground, and starter solenoid as potential causes of your Snapper’s failure to start. You can take out the starter and test it.
Before purchasing an expensive new starter for your Snapper mower, I advise having your starter tested and, if possible, rebuilt by a nearby repair business that specializes in starter and alternator repairs.
