Case 580 Super K Overview
The Case 580 Super K is a widely respected backhoe loader introduced in the early 1990s, known for its mechanical simplicity, reliability, and versatility in construction and agricultural applications. Powered by a Case 4-390 diesel engine producing around 75 horsepower, the Super K features a mechanical shuttle transmission, open-center hydraulics, and a robust electrical system designed for field serviceability. Case Construction Equipment, with roots dating back to 1842, has sold hundreds of thousands of 580-series machines globally, and the Super K remains a favorite among owner-operators and municipalities.
Terminology Notes
On the Case 580 Super K, the fuse box is typically located behind the right-side dash panel or under the steering column, depending on the year and cab configuration. Access requires removing a plastic or metal cover, often secured with screws or clips. Once exposed, the fuse panel reveals a row of blade-type fuses, each corresponding to a specific circuit.
Common Fuse Assignments
While exact layouts may vary slightly by model year and optional equipment, a typical 580 Super K fuse panel includes:
In Queensland, a diesel technician servicing a 580 Super K found that a failed instrument cluster was traced to a blown 10A fuse hidden behind a dusty panel. The operator had been unaware of the fuse box location and had replaced the gauge cluster unnecessarily. After cleaning the contacts and replacing the fuse, the system worked flawlessly.
In rural Indiana, a farmer lost all lighting on his Super K during a night job. After checking the fuse panel, he discovered corrosion on the fuse terminals. A quick cleaning with contact spray and a new 15A fuse restored full lighting.
Recommendations for Owners and Technicians
The fuse box on the Case 580 Super K is a critical yet often overlooked component. Understanding its layout and maintaining clean, labeled connections can prevent downtime and simplify troubleshooting. With a few spare fuses and basic tools, operators can resolve most electrical issues in the field and keep this legendary backhoe working hard for decades to come.

Terminology Notes
- Fuse Box: A centralized panel containing fuses that protect electrical circuits from overcurrent.
- Blade-Type Fuse: A flat, plastic-encased fuse with two metal prongs, common in automotive and equipment applications.
- Accessory Circuit: An electrical path powering non-essential systems like lights, horn, or auxiliary sockets.
- Ignition Circuit: The electrical path that powers engine starting and control systems.

Common Fuse Assignments
While exact layouts may vary slightly by model year and optional equipment, a typical 580 Super K fuse panel includes:
- 10A – Instrument Cluster: Powers gauges, warning lights, and hour meter.
- 15A – Headlights: Controls front work lights and high/low beam circuits.
- 10A – Turn Signals and Brake Lights: Essential for road transport compliance.
- 20A – Cab Heater and Fan: Powers blower motor and HVAC controls.
- 15A – Horn and Accessory Socket: Includes 12V outlet and horn circuit.
- 10A – Transmission Solenoids: Controls directional shift solenoids in power shuttle models.
- 10A – Fuel Shutoff Solenoid: Powers the solenoid that enables engine shutdown.
- Spare Fuses: Often included in the panel for quick replacement in the field.

Recommendations for Owners and Technicians
- Label the Fuse Panel: Use a laminated diagram or sticker to identify each fuse and its function.
- Carry Spare Fuses: Keep a kit of 10A, 15A, and 20A blade fuses in the cab.
- Inspect for Corrosion: Moisture and dust can cause poor contact or fuse failure.
- Use Dielectric Grease on Terminals: Prevents oxidation and improves conductivity.
- Check Grounds and Relays: A blown fuse may indicate a deeper issue like a shorted wire or failed relay.
