Introduction
Starter issues in heavy equipment can be frustrating, especially when the machine is essential for daily operations. One of the most common problems faced by operators of skid steers like the LS170 is starter failure, which can cause significant delays in work and even result in costly repairs if not addressed promptly. In this article, we will discuss the common causes of starter issues in the LS170, provide a step-by-step guide for troubleshooting, and share practical tips for fixing or replacing the starter system.
Common Symptoms of Starter Issues
Before diving into troubleshooting, it’s important to recognize the symptoms of starter problems. On the LS170, these signs could include:
Possible Causes of Starter Problems
Several factors can contribute to starter issues in the LS170. Below are the common causes, with a description of how they can impact the starter system:
Here is a step-by-step guide to troubleshoot starter problems on the LS170:
1. Check the Battery
Start by inspecting the battery as it is the most common cause of starting issues. If the battery is dead or weak, the starter motor will not have enough power to turn the engine over.
Corroded or loose battery terminals are a common cause of starting issues. Inspect the battery terminals for corrosion and clean them if necessary. Here’s how:
If the battery is in good condition and the terminals are clean, the next step is to check the starter solenoid. The solenoid is responsible for engaging the starter motor when you turn the key.
If the solenoid is functioning correctly, the next component to inspect is the starter motor.
A faulty ignition switch can prevent the proper signal from reaching the starter solenoid. If all of the previous components appear to be working, test the ignition switch:
In some cases, a blown fuse or faulty relay can cause starter issues. Check the fuses and relays in the starter circuit to ensure they are in good condition.
Starter issues on the LS170 skid steer can be frustrating, but with a methodical troubleshooting approach, many problems can be identified and resolved. By inspecting the battery, terminals, starter solenoid, and starter motor, you can quickly narrow down the cause of the issue and take the necessary steps to fix it.
Remember, regular maintenance of the starting system can help prevent many of these problems before they occur. Keeping the battery charged, cleaning terminals, and inspecting electrical connections periodically will ensure that your LS170 is ready to start when you need it most.

Common Symptoms of Starter Issues
Before diving into troubleshooting, it’s important to recognize the symptoms of starter problems. On the LS170, these signs could include:
- Engine Won’t Crank: When you turn the key, you hear no cranking noise or the engine doesn’t turn over at all.
- Slow Cranking: The engine cranks but slowly, sometimes taking several attempts before it starts.
- Clicking Noise: When attempting to start, the starter makes a repetitive clicking noise, indicating that the starter is not engaging properly.
- No Sound: There may be no sound at all, signaling an electrical issue or a failed starter motor.
Possible Causes of Starter Problems
Several factors can contribute to starter issues in the LS170. Below are the common causes, with a description of how they can impact the starter system:
- Dead or Weak Battery: The most common culprit in starting problems is a weak or dead battery. If the battery doesn’t have enough charge to provide the required power to the starter motor, the engine may fail to crank or start. Batteries can lose charge due to prolonged inactivity, extreme weather conditions, or age.
- Corroded Battery Terminals: Corrosion around the battery terminals can prevent proper electrical contact, leading to poor power flow. This can result in slow cranking or no cranking at all.
- Faulty Starter Solenoid: The starter solenoid is a critical component that connects the battery’s power to the starter motor. If it becomes damaged or fails, it can prevent the starter motor from engaging, leading to clicking sounds or no action when attempting to start the engine.
- Worn-out Starter Motor: Over time, the starter motor can wear out due to excessive use, especially under harsh conditions. A worn-out starter will struggle to turn the engine over and may eventually fail entirely.
- Faulty Ignition Switch: If the ignition switch is damaged, it may fail to send the proper signal to the starter solenoid to engage the starter motor.
- Electrical Wiring Issues: Any loose, damaged, or corroded wires in the starting circuit can lead to intermittent or complete failure of the starting system.
- Weak or Old Battery Cables: The battery cables themselves can become worn or damaged, affecting their ability to deliver power to the starter motor. Poor cable connections can create resistance, reducing the voltage available to the starter.
Here is a step-by-step guide to troubleshoot starter problems on the LS170:
1. Check the Battery
Start by inspecting the battery as it is the most common cause of starting issues. If the battery is dead or weak, the starter motor will not have enough power to turn the engine over.
- Test the battery voltage: Using a multimeter, measure the battery voltage. A healthy 12-volt battery should read around 12.6 volts when fully charged. If the voltage is significantly lower, the battery may need to be charged or replaced.
- Check the battery charge: If the voltage is low, try charging the battery. If it does not hold a charge, it may need to be replaced.
Corroded or loose battery terminals are a common cause of starting issues. Inspect the battery terminals for corrosion and clean them if necessary. Here’s how:
- Clean the terminals: Use a mixture of baking soda and water to clean any corrosion off the terminals. Be sure to wear gloves and safety goggles, as the corrosion can be hazardous.
- Tighten connections: Ensure that the battery terminals are tight and secure. Loose connections can prevent the proper flow of electricity.
- Check the battery cables: Inspect the battery cables for wear or damage. If any cables are frayed, cracked, or corroded, they may need to be replaced.
If the battery is in good condition and the terminals are clean, the next step is to check the starter solenoid. The solenoid is responsible for engaging the starter motor when you turn the key.
- Listen for clicks: When attempting to start the engine, listen carefully for a clicking sound. If you hear a single click or rapid clicking, it could indicate a faulty solenoid.
- Check for voltage: Use a multimeter to check the voltage going to the solenoid. If there is no voltage at the solenoid when the ignition is turned to the start position, the issue may be in the ignition switch or wiring.
If the solenoid is functioning correctly, the next component to inspect is the starter motor.
- Check for wear: Over time, starter motors can wear out and become inefficient. If the motor is making a grinding noise or is unable to turn the engine over, it may need to be replaced.
- Test the motor directly: To test the starter motor, remove it from the engine and connect it directly to the battery. If it does not turn over, the motor is likely faulty and will need to be replaced.
A faulty ignition switch can prevent the proper signal from reaching the starter solenoid. If all of the previous components appear to be working, test the ignition switch:
- Check continuity: Use a multimeter to check for continuity in the ignition switch. If the switch is faulty, it may need to be replaced.
- Inspect wiring: Look for any loose or damaged wires in the starting circuit. A damaged wire can cause intermittent starting issues, and may need to be repaired or replaced.
In some cases, a blown fuse or faulty relay can cause starter issues. Check the fuses and relays in the starter circuit to ensure they are in good condition.
- Inspect fuses: Replace any blown fuses and ensure that all fuses are the correct amperage for the system.
- Test relays: If a relay is clicking but not engaging, it may be defective and should be replaced.
Starter issues on the LS170 skid steer can be frustrating, but with a methodical troubleshooting approach, many problems can be identified and resolved. By inspecting the battery, terminals, starter solenoid, and starter motor, you can quickly narrow down the cause of the issue and take the necessary steps to fix it.
