The Bobcat 863 is a popular skid-steer loader known for its reliability in construction, landscaping, and material handling. However, like all heavy machinery, it can experience electrical or mechanical issues that disrupt its operation. One of the more perplexing issues is when a Bobcat 863, equipped with side steer controls, won't turn over or lacks power to the cab. This type of problem can stem from various causes, ranging from electrical failures to mechanical blockages. Understanding the potential causes and how to troubleshoot them can help operators resolve the issue efficiently.
Understanding the Problem: No Turnover and No Power to the Cab
When the Bobcat 863 fails to turn over and the cab has no power, it can be due to several electrical or mechanical issues. The "no power" symptom often points to a problem with the battery, alternator, or wiring, while the failure to turn over suggests an issue with the starter motor, ignition system, or associated components.
Here are some of the primary components involved in such issues:
To resolve the issue of no power and failure to turn over in the Bobcat 863, follow these troubleshooting steps:
Several underlying causes can result in no power or failure to start in the Bobcat 863. Below are some common reasons for these symptoms:
While many of these issues can be resolved with basic tools and a multimeter, some situations require professional assistance. If you are unable to diagnose the issue, or if the electrical system appears to be severely damaged, it’s best to consult a certified Bobcat technician. They have the specialized tools and experience needed to identify and fix complex electrical or mechanical problems.

When the Bobcat 863 side steer won’t turn over or has no power to the cab, it’s essential to systematically troubleshoot the electrical and mechanical components that could be causing the issue. Start with the battery, alternator, wiring, and starter motor, then move on to the ignition switch if necessary. By following a detailed inspection process and addressing potential causes early, you can get your Bobcat 863 back to full working condition. Regular maintenance and prompt attention to electrical issues will help ensure long-term reliability of your equipment.
Understanding the Problem: No Turnover and No Power to the Cab
When the Bobcat 863 fails to turn over and the cab has no power, it can be due to several electrical or mechanical issues. The "no power" symptom often points to a problem with the battery, alternator, or wiring, while the failure to turn over suggests an issue with the starter motor, ignition system, or associated components.
Here are some of the primary components involved in such issues:
- Battery: The battery is the primary power source for starting the engine and supplying electrical systems. If the battery is dead or weak, the machine may fail to start and have no power.
- Alternator: The alternator keeps the battery charged and powers the cab's electrical systems. A faulty alternator can result in a lack of power.
- Wiring and Fuses: Loose or corroded connections, damaged wiring, or blown fuses can interrupt power flow to the cab and starter.
- Starter Motor: If the starter motor is malfunctioning, the engine may fail to turn over, despite power being supplied to other components.
- Ignition Switch: A faulty ignition switch can prevent the machine from starting by failing to send the correct signals to the starter motor.
To resolve the issue of no power and failure to turn over in the Bobcat 863, follow these troubleshooting steps:
- Check the Battery:
- Inspect the battery for signs of damage, corrosion, or leakage.
- Ensure that the battery terminals are clean and tightly connected.
- Use a multimeter to check the battery voltage. A healthy battery should read around 12.6 volts when fully charged. If the voltage is lower than 12 volts, the battery may need to be charged or replaced.
- If the battery is old, it may no longer hold a charge properly and should be replaced.
- Inspect the battery for signs of damage, corrosion, or leakage.
- Inspect the Alternator:
- The alternator’s job is to charge the battery while the engine is running. If the alternator is faulty, the battery may not be charging correctly.
- Test the alternator by checking the voltage at the battery terminals with the engine running. You should see a voltage between 13.5 and 14.5 volts. If the voltage is lower, the alternator may be defective.
- The alternator’s job is to charge the battery while the engine is running. If the alternator is faulty, the battery may not be charging correctly.
- Examine the Wiring and Fuses:
- Visually inspect the wiring harness for any signs of wear, corrosion, or damage. Look for any loose connections, especially around the starter motor, battery, and ignition switch.
- Check the fuse panel and ensure that none of the fuses are blown. A blown fuse can prevent power from reaching critical components like the cab or starter motor.
- Visually inspect the wiring harness for any signs of wear, corrosion, or damage. Look for any loose connections, especially around the starter motor, battery, and ignition switch.
- Test the Starter Motor:
- The starter motor is responsible for turning over the engine when the ignition switch is engaged. If the starter motor is malfunctioning, the engine will not start.
- To test the starter, you can perform a bench test by removing it from the machine and applying direct power to the terminals. If the motor does not spin, it may need to be replaced.
- The starter motor is responsible for turning over the engine when the ignition switch is engaged. If the starter motor is malfunctioning, the engine will not start.
- Inspect the Ignition Switch:
- The ignition switch sends a signal to the starter motor to initiate the starting process. If the ignition switch is faulty, it may not be sending the proper signal to the starter.
- Check the ignition switch by testing continuity with a multimeter. If there is no continuity when the switch is in the "start" position, the switch may need to be replaced.
- The ignition switch sends a signal to the starter motor to initiate the starting process. If the ignition switch is faulty, it may not be sending the proper signal to the starter.
Several underlying causes can result in no power or failure to start in the Bobcat 863. Below are some common reasons for these symptoms:
- Corroded Battery Terminals: Corrosion at the battery terminals can impede the flow of electrical current, preventing the machine from starting or powering the cab.
- Loose or Disconnected Wiring: A loose connection anywhere in the electrical system, especially at the starter motor or ignition switch, can interrupt power delivery.
- Faulty Grounding: A poor ground connection can prevent the electrical system from functioning correctly. Check all ground straps and connections to ensure they are secure and free of rust or corrosion.
- Faulty Fuses or Relays: Blown fuses or malfunctioning relays can cut off power to vital components, causing the machine to fail to turn over or power the cab.
- Failed Alternator: A failed alternator will not charge the battery, which can lead to power loss and starting issues.
- Aging Battery: A battery that has reached the end of its lifespan will not provide enough power to start the engine or run the electrical systems.
While many of these issues can be resolved with basic tools and a multimeter, some situations require professional assistance. If you are unable to diagnose the issue, or if the electrical system appears to be severely damaged, it’s best to consult a certified Bobcat technician. They have the specialized tools and experience needed to identify and fix complex electrical or mechanical problems.
Preventive Maintenance Tips
To avoid similar problems in the future, consider implementing the following maintenance practices for the Bobcat 863:
- Regular Battery Maintenance: Clean battery terminals and check the charge regularly. If the battery is more than 3-5 years old, consider replacing it before it fails.
- Routine Inspection of Wiring and Fuses: Periodically inspect the wiring and fuse panels for signs of wear, corrosion, or damage.
- Alternator Checks: Ensure the alternator is functioning properly, especially during seasonal maintenance checks, to prevent battery charging issues.
- Keep Connections Tight: Ensure that all electrical connections are tight and free of corrosion, including ground connections.
When the Bobcat 863 side steer won’t turn over or has no power to the cab, it’s essential to systematically troubleshoot the electrical and mechanical components that could be causing the issue. Start with the battery, alternator, wiring, and starter motor, then move on to the ignition switch if necessary.
