Troubleshooting Guide: 16hp Briggs & Stratton Starter – 5 Fixes for Splitters

I’ve spent years felling trees, processing logs, and splitting firewood, both for personal use and as part of small-scale timber operations. I’ve seen firsthand how a balky starter can derail an entire day’s work. I remember one particularly cold winter morning, trying to get a splitter started with a stubborn starter. After what felt like an eternity of pulling the cord, I finally figured out the problem was a simple loose connection. These experiences have taught me the importance of understanding the common issues and how to address them efficiently. This guide is based on my experiences and focuses on practical solutions you can implement yourself.

Understanding the Starter System

Before we delve into the fixes, let’s define some key terms and understand the basic principles of a starter system.

• Starter Motor: The electric motor that cranks the engine to initiate combustion.
• Solenoid: An electromagnetic switch that connects the battery to the starter motor.
• Bendix Drive: A gear mechanism that engages the starter motor with the engine’s flywheel.
• Flywheel: A heavy wheel connected to the engine’s crankshaft, which helps maintain momentum and provide a surface for the starter to engage.

A typical starter system works like this: When you turn the ignition key, the solenoid receives a signal. The solenoid then closes a circuit, allowing high-amperage current from the battery to flow to the starter motor. The starter motor spins, and the Bendix drive engages with the flywheel, turning the engine’s crankshaft. Once the engine starts, the Bendix drive disengages, preventing the starter motor from being damaged by the higher engine speed.

Fix 1: Checking the Battery and Connections

The most common cause of a starter problem is a weak battery or poor connections. Here’s how to check them:

1. Safety First: Disconnect the spark plug wire to prevent accidental starting. Wear safety glasses and gloves.
2. Battery Voltage Test: Use a multimeter to check the battery voltage. A fully charged 12-volt battery should read around 12.6 volts. If it’s below 12 volts, the battery is likely weak and needs charging or replacement.
   • Tool Specification: Digital Multimeter (minimum DC voltage range: 0-20V)
   • Measurement: Record the voltage reading.
3. Clean Battery Terminals: Inspect the battery terminals for corrosion. If you see any, disconnect the cables and clean the terminals with a wire brush or a specialized battery terminal cleaner. Reconnect the cables securely, ensuring good contact.
   • Tool Specification: Wire brush or battery terminal cleaner.
4. Check Cable Connections: Follow the battery cables to the solenoid and starter motor. Inspect these connections for corrosion or looseness. Clean and tighten them as needed. Pay special attention to the ground connection, as a poor ground can cause significant starting problems.
   • Tip: Applying a thin coat of dielectric grease to the terminals after cleaning can help prevent future corrosion.

Case Study: I once spent an hour troubleshooting a “dead” starter, only to discover that the negative battery cable was barely hanging on. A simple tightening of the connection solved the problem. This highlights the importance of starting with the basics.

Strategic Advantage: Regularly checking and cleaning battery connections (at least twice a year) can prevent many starting problems and extend the life of your battery.

Fix 2: Inspecting the Solenoid

The solenoid is a critical component in the starting circuit. Here’s how to test it:

1. Locate the Solenoid: The solenoid is usually mounted near the starter motor or on the engine block. It’s a small, cylindrical device with several terminals.
2. Solenoid Click Test: With the key in the “start” position, listen for a “click” from the solenoid. If you hear a click, the solenoid is likely receiving power and attempting to engage. If you don’t hear a click, proceed to the next step.
3. Voltage Test: Use a multimeter to check for voltage at the solenoid terminals. With the key in the “start” position, you should see 12 volts at the small terminal that receives the signal from the ignition switch. If you don’t, there may be a problem with the ignition switch or wiring.
   • Tool Specification: Digital Multimeter (minimum DC voltage range: 0-20V)
   • Measurement: Record the voltage reading.
4. Bypass Test: Carefully bypass the solenoid by using a screwdriver to connect the two large terminals. This will directly send power to the starter motor. If the starter motor spins, the solenoid is faulty and needs replacement.
   • Caution: This test should be performed with extreme care. Ensure the splitter is in neutral and the spark plug wire is disconnected.
   • Note: If the starter spins when bypassing the solenoid, but not when using the ignition switch, the solenoid is the issue.

Personalized Story: I had a solenoid fail on a splitter during a large firewood processing job. I used a jumper cable to bypass the solenoid temporarily to keep the operation running until I could get a replacement. This highlights the importance of understanding basic electrical troubleshooting.

Technical Detail: A typical solenoid for a 16hp Briggs & Stratton engine costs between $20 and $40.

Fix 3: Examining the Starter Motor

If the battery and solenoid are functioning correctly, the problem may lie within the starter motor itself.

1. Visual Inspection: Inspect the starter motor for any signs of physical damage, such as cracks or broken wires.
2. Direct Power Test: Disconnect the starter motor from the solenoid. Using jumper cables connected directly to the battery, carefully apply power to the starter motor. If the starter motor doesn’t spin, it’s likely faulty and needs replacement or repair.
   • Caution: This test should be performed with extreme care. Ensure the splitter is in neutral and the spark plug wire is disconnected.
3. Brush Inspection (If Applicable): Some starter motors have replaceable brushes. If your starter motor is of this type, remove the end cap and inspect the brushes for wear. If the brushes are worn down to the point where they no longer make good contact with the commutator, they need to be replaced.
   • Tool Specification: Screwdrivers, pliers.
4. Professional Repair: If you’re not comfortable disassembling the starter motor, take it to a qualified repair shop. They can diagnose the problem and either repair or replace the starter.

Original Insight: Often, starter motor failure is due to worn brushes. Replacing the brushes can be a much cheaper alternative to replacing the entire starter motor. I’ve successfully rebuilt several starter motors by simply replacing the brushes.

Cost Consideration: Replacing the brushes in a starter motor typically costs between $10 and $20, while a new starter motor can cost between $80 and $150.

Fix 4: Checking the Bendix Drive

The Bendix drive is responsible for engaging the starter motor with the engine’s flywheel. If the Bendix drive is not functioning correctly, the starter motor may spin, but the engine won’t crank.

1. Visual Inspection: Remove the starter motor from the engine. Inspect the Bendix drive for any signs of damage, such as broken teeth or excessive wear.
2. Manual Engagement Test: Manually try to engage the Bendix drive with the flywheel. It should move freely and engage smoothly. If it’s stuck or binding, it may need lubrication or replacement.
   • Tip: Use a light lubricant, such as WD-40, to lubricate the Bendix drive mechanism.
3. Flywheel Inspection: Inspect the flywheel teeth for damage. If the teeth are worn or broken, the Bendix drive may not be able to engage properly. The flywheel may need to be replaced or repaired.

Example from Real Project: I once encountered a splitter that would only start intermittently. After inspecting the Bendix drive, I found that the teeth were worn down on one side. Replacing the Bendix drive solved the problem.

Measurement: Measure the height of the Bendix drive teeth using calipers. Compare the measurement to the manufacturer’s specifications. If the teeth are worn beyond the acceptable limit, the Bendix drive needs to be replaced.

Fix 5: Addressing Engine Issues

In some cases, a starting problem may not be related to the starter system at all, but rather to an underlying engine issue.

1. Compression Test: Perform a compression test to check the engine’s compression. Low compression can make it difficult for the engine to start.
   • Tool Specification: Compression tester.
   • Measurement: Record the compression reading for each cylinder. Compare the readings to the manufacturer’s specifications.
2. Fuel System Check: Ensure that the engine is receiving fuel. Check the fuel filter, fuel lines, and carburetor for any blockages or leaks.
3. Spark Plug Check: Inspect the spark plug for fouling or damage. A fouled or damaged spark plug can prevent the engine from starting.
   • Tool Specification: Spark plug wrench, spark plug gap tool.
   • Measurement: Check the spark plug gap using a spark plug gap tool. Adjust the gap to the manufacturer’s specifications.

Technical Detail: A 16hp Briggs & Stratton engine should have a compression reading of at least 80 PSI.

Wood Type Selection and Its Impact: The type of wood you’re splitting can also indirectly affect your starter. Harder woods like oak or hickory require more power to split, and if your engine is already struggling, the added load can make starting even more difficult. Ensure your engine is properly tuned and maintained to handle the demands of splitting harder woods.

Drying Methods and Starter Strain: Splitting green wood versus seasoned wood also impacts the load on the engine. Green wood is heavier and more difficult to split, placing more strain on the engine during startup. Seasoned wood, with its lower moisture content, is easier to split, reducing the strain on the engine and starter.

Additional Tips and Considerations

• Cold Weather Starting: Cold weather can make starting any engine more difficult. Use a starting fluid to help the engine start more easily in cold conditions.
  • Caution: Use starting fluid sparingly, as excessive use can damage the engine.
• Maintenance Schedule: Follow the manufacturer’s recommended maintenance schedule for your engine. Regular maintenance, such as oil changes and air filter cleaning, can help prevent starting problems.
• Safety Precautions: Always disconnect the spark plug wire before working on the starter system. Wear safety glasses and gloves to protect yourself from injury.
• Professional Assistance: If you’re not comfortable troubleshooting the starter system yourself, take the splitter to a qualified mechanic.
