Craftsman Riding Mower Won’t Start with New Battery: Troubleshooting Guide

Craftsman riding mower won’t start with a new battery, possible causes may include a faulty ignition switch or a starter solenoid issue. This article will explore common reasons for a riding mower’s failure to start, providing troubleshooting tips to help resolve the problem and get your mower running smoothly again.

Craftsman Mower: New Battery, Still Won’t Start: Quick Troubleshooting

This guide will walk you through diagnosing and solving why your Craftsman mower won’t start.

Step 1: Safety First

• Disconnect the spark plug! Before you touch anything else under the hood, disconnect the spark plug wire. This ensures there’s zero chance of the engine accidentally starting while you’re working.
• While not always strictly necessary, it’s good practice to wear some eye protection and work gloves when troubleshooting mower problems.

Step 2: Ruling Out the Simple Issues

• Faulty Battery: Yes, even new batteries can sometimes be bad. If you have a multimeter, test the voltage – it should be at least 12.4 volts. Auto parts stores can also often test batteries for free.
• Loose Connections: Check that the battery terminals are clean, tight, and free of corrosion. A loose connection could prevent power from reaching the starter
• Safety Switches: Modern mowers have several safety features. Make sure the parking brake is set, you’re in the seat, and the PTO (power take-off for the blades) is disengaged. Check your manual if you’re unsure.
• Bad Fuel: Old, stale gasoline can cause starting trouble. If the fuel has been sitting for more than a month or two, it might be best to drain it and replace it with fresh gas.

Step 3: Diagnosing Deeper

• Starter Solenoid: This little electrical switch sends power to the starter motor. A faulty solenoid often makes a “clicking” sound but doesn’t turn the engine over. You can usually find it by following the thick red cable from the battery’s positive terminal. Online videos demonstrate how to test a solenoid.
• Ignition Switch: Your mower’s key switch may be the culprit. Just like in a car, a faulty ignition switch cuts off the power needed to start. Testing usually involves checking for voltage with a multimeter.
• Fuses: Most mowers have a fuse to protect the electrical system. A blown fuse will prevent starting. Refer to your owner’s manual to locate the fuse and check its condition.
• Seized Engine: This is a worst-case scenario, but it happens. If the engine is extremely hard to turn by hand (even with the spark plug out), it could be seized. This requires professional repair.

Step 4: Additional Considerations

• Wiring Damage: Inspect the wiring for fraying, broken wires, or signs of chewing by rodents. Damaged wiring needs repair.
• Fuel System (Optional): Clogged fuel lines, dirty fuel filters, and gummed-up carburetors can also prevent starting. These problems might deserve their own dedicated blog post.

Step 5: If All Else Fails

• Consulting the Manual: Owner’s manuals have wiring diagrams and specific information on safety switch locations.
• Seeking Professional Help: If you’ve tried these steps and still can’t get the mower running, it may be time to call in a mechanic.
