The Bobcat S185 Skid Steer Loader is a compact and versatile machine used in construction, landscaping, and agricultural industries. Known for its maneuverability and efficiency, the S185 is equipped with various electrical components, including a fuse box and relay system.
The fuse box in the Bobcat S185 protects electrical circuits from overloads, preventing damage to critical components such as the engine, hydraulic systems, and electrical controls. It houses fuses that are designed to break the circuit if excessive current flows through them, thereby safeguarding the electrical system from potential hazards.
Relays in the S185 act as electrically operated switches that control high-current circuits, enabling precise operation of functions such as lifting arms, auxiliary attachments, and lights. These relays help manage power distribution efficiently throughout the machine, ensuring smooth operation and reducing the risk of electrical failures.
Regular inspection and maintenance of the fuse box and relays are essential to ensure the reliable performance of the Bobcat S185 Skid Steer Loader. Operators and maintenance personnel should periodically check fuses for signs of wear or damage and replace them as necessary. Additionally, verifying proper relay function and ensuring secure connections can help prevent downtime and optimize productivity on job sites.

WARNING
- Never replace a fuse with one that has a higher amperage rating.
- A fuse with a too-high amperage could damage the electrical part and cause a fire.
- On no account should fuses be repaired (e.g. patched up with tin foil or wire) as this may cause serious damage elsewhere in the electrical circuit or cause a fire.
- If a fuse blows repeatedly, do not keep replacing it. Instead, have the cause for the repeated short circuit or overload tracked and fixed.
- Terminal and harness assignments for individual connectors will vary depending on vehicle equipment level, model, and market.

The loader has a 12 volt, negative ground alternator charging system. The electrical system is protected by fuses located in the cab on the steering control panel, and a 100 ampere master fuse in the engine compartment on the left side of the engine, under the air cleaner. The fuses will protect the electrical system when there is an electrical overload. The reason for the overload must be found before starting the engine again.
The electrical system is protected from overload by fuses and relays under the fuse panel cover (Item 1). A decal is inside the cover to show location and amperage ratings. Remove the cover to check or replace the fuses.
