CASE 1845C Slow Crank No Start: Troubleshooting and Solutions

[MikePhua]

The CASE 1845C skid steer loader is a powerful and reliable machine, but like any piece of equipment, it can encounter issues. One common problem that users experience is a slow crank or no start situation, which can lead to frustration and downtime. This article will explore the possible causes of a slow crank or no start issue on a CASE 1845C and provide solutions to get your machine up and running again.
Possible Causes of Slow Crank or No Start
When your CASE 1845C is cranking slowly or failing to start, it could be due to various mechanical or electrical issues. Below are the most common causes and their potential solutions:
1. Weak or Dead Battery
A weak or dead battery is one of the most common reasons for slow cranking or no start. If the battery is not providing enough power to turn the engine over, the machine may struggle to start or fail to start entirely.

• Solution:
  • Check the battery voltage using a multimeter. A healthy, fully charged battery should show around 12.6 volts.
    
  • If the battery voltage is low, charge the battery and try starting the machine again.
    
  • If the battery is old or damaged, it may need to be replaced.
    

2. Faulty Starter Motor
The starter motor is responsible for turning the engine over. If the starter motor is faulty, it may not engage properly, causing slow cranking or no start.

• Solution:
  • Inspect the starter motor for any visible signs of damage or wear.
    
  • If the starter motor is not functioning properly, it may need to be repaired or replaced.
    
  • Ensure that all connections to the starter motor are clean and tight.
    

3. Poor Battery Connections
Loose or corroded battery terminals can cause poor electrical connections, resulting in insufficient power to the starter motor and slow cranking.

• Solution:
  • Inspect the battery terminals for corrosion or dirt buildup. Clean the terminals with a wire brush if necessary.
    
  • Check that the battery cables are securely attached to the battery terminals. Tighten any loose connections.
    

4. Bad Alternator
The alternator is responsible for charging the battery while the machine is running. If the alternator is not working properly, the battery may not be getting charged, leading to a weak or dead battery, and causing starting issues.

• Solution:
  • Test the alternator by checking the battery voltage with the engine running. The voltage should be between 13.8 and 14.5 volts.
    
  • If the voltage is below this range, the alternator may be faulty and should be inspected or replaced.
    

5. Fuel System Problems
A lack of fuel or an issue with the fuel system can also cause a no-start condition. If the engine is not getting fuel, it will not start, regardless of how well the starter motor works.

• Solution:
  • Check the fuel tank to ensure there is enough fuel.
    
  • Inspect the fuel lines and filter for any clogs or leaks that may be preventing fuel from reaching the engine.
    
  • Replace the fuel filter if it is clogged or dirty.
    

6. Ignition Switch or Wiring Issues
If the ignition switch or wiring is faulty, the electrical signals may not be reaching the starter motor or fuel system, preventing the engine from starting.

• Solution:
  • Check the ignition switch for proper function. If it is damaged or malfunctioning, it may need to be replaced.
    
  • Inspect the wiring for any loose connections, frayed wires, or signs of damage. Repair or replace any damaged wiring.
    

7. Glow Plug Problems (for Diesel Engines)
For diesel-powered CASE 1845C skid steers, glow plugs are crucial for starting the engine, especially in cold weather. If the glow plugs are not functioning properly, the engine may fail to start, even if the starter motor is working.

• Solution:
  • Test the glow plugs to ensure they are working properly. If one or more glow plugs are faulty, they should be replaced.
    
  • Make sure the glow plug relay and wiring are in good condition.
    

Steps to Troubleshoot and Resolve Slow Crank or No Start

1. Check the Battery:
   Begin by checking the battery voltage and condition. Charge the battery or replace it if necessary.
   
2. Inspect the Starter Motor:
   Test the starter motor by listening for unusual sounds or checking if it engages correctly. Replace it if it is faulty.
   
3. Examine Battery Connections:
   Clean and tighten the battery terminals to ensure proper electrical connections.
   
4. Test the Alternator:
   Start the engine and check the battery voltage with a multimeter. If the alternator is faulty, it may need to be replaced.
   
5. Check the Fuel System:
   Make sure there is sufficient fuel and inspect the fuel system for blockages or leaks.
   
6. Inspect the Ignition System:
   Check the ignition switch and wiring for any faults, and replace any damaged components.
   
7. Test the Glow Plugs (for Diesel Engines):
   If your CASE 1845C is diesel-powered, test the glow plugs to ensure they are functioning properly.
   

Conclusion
A slow crank or no start issue on the CASE 1845C skid steer loader can be caused by several factors, ranging from a weak battery to fuel system issues. By systematically checking the battery, starter motor, fuel system, and electrical components, you can identify the root cause of the problem and take the necessary steps to fix it. Regular maintenance and troubleshooting can ensure your CASE 1845C runs smoothly and reliably for years to come.
