Learn about Ford Focus Electric (EU) (2013-2017) fuse box and relay’s locations, functions, and maintenance tips for optimal vehicle electrical system.
The Ford Focus Electric brought fully electric power to the popular Focus platform, offering European drivers a zero-emission alternative without sacrificing the practicality of a familiar hatchback design. While this EV shares much of its body and interior with the conventional Focus, its electrical system includes some unique elements related to battery management and electric drive components, alongside the standard fuses and relays found in any modern vehicle.
Fuses and relays protect your Focus Electric’s wiring from power surges and short circuits, whether it’s managing interior accessories, exterior lighting, or components tied to the high-voltage drive system. If you’re experiencing issues like non-working interior lights, a malfunctioning infotainment screen, or problems with charging system indicators, checking the fuse box is a sensible first step, though extra caution is needed given the presence of high-voltage components.
This guide covers the fuse box and relay locations for the 2013–2017 Ford Focus Electric (EU), along with important safety considerations specific to electric vehicles.

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.

Where Are the Fuse Boxes Located on the Ford Focus Electric?
The Focus Electric uses two main fuse box locations: one in the front compartment (where a traditional engine would be) and one inside the cabin. Because this is an EV, the front compartment houses electric drive components alongside the low-voltage fuse box, rather than a combustion engine.
1. Front Compartment Fuse Box (Power Distribution Box)
The primary low-voltage fuse box is located in the front compartment, positioned near the battery on the driver’s side, similar in placement to where you’d find it on a conventional Focus.
How to access it:
- Open the front hood and locate the black plastic cover near the 12-volt auxiliary battery.
- Unclip or unscrew the retaining tabs securing the cover.
- Lift the cover straight up to expose the fuses and relays inside.
This fuse box handles the vehicle’s low-voltage (12V) circuits, including headlights, horn, wipers, and the cooling fans used for the battery thermal management system. It’s important to note this box does not contain high-voltage fuses related to the main drive battery, those are handled by a separate, sealed high-voltage system not intended for owner access.
2. Interior Fuse Panel (Instrument Panel Fuse Box)
The cabin fuse box is located inside the vehicle, typically under the dashboard on the driver’s side, near the left kick panel area.
How to access it:
- Sit in the driver’s seat and locate the small access panel to the left of the steering column, near the door.
- Gently pull or unclip the cover, it’s usually secured with simple plastic retaining clips.
- Once removed, you’ll see the fuse layout along with several compact relays.
This panel controls circuits such as interior lighting, the infotainment system, power windows, wipers, and dashboard displays, including the EV-specific battery charge and range indicators.
3. High-Voltage System Components (Not User-Serviceable)
Unlike the low-voltage fuses and relays covered in this guide, the Focus Electric’s high-voltage battery pack and associated components are protected by a sealed high-voltage fuse and disconnect system, located within the battery pack enclosure itself. This system is designed to be serviced only by trained technicians using specialized equipment and safety gear.
Important: Never attempt to open, inspect, or service any high-voltage orange-colored cabling, connectors, or components. These carry extremely dangerous voltage levels and require professional handling.
How to Identify the Right Fuse or Relay
Both the front compartment and interior fuse boxes include a printed diagram, usually located on the inside of the fuse box cover, detailing each fuse and relay by number, amperage rating, and function.
When troubleshooting:
- Identify the malfunctioning component (e.g., “wipers” or “infotainment system”) and match it to its corresponding number on the diagram.
- Confirm the amperage rating on the old fuse matches the replacement before installing a new one.
- For relays, use the diagram to confirm the correct slot, since several relays may look similar despite controlling different systems.
If the printed diagram is missing or difficult to read, refer to your owner’s manual for a detailed fuse box diagram specific to your Focus Electric, since EV-specific circuits differ from the standard petrol or diesel Focus models.
Safety Precautions Before Checking Fuses or Relays
Working on an electric vehicle requires extra caution beyond standard fuse-checking procedures:
- Turn off the vehicle completely and remove the key (or ensure the key fob is out of range) before accessing any fuse or relay.
- Only work on the low-voltage fuse boxes described in this guide, never attempt to access high-voltage components, which are colored orange and sealed for safety.
- If you need to disconnect the 12-volt auxiliary battery for electrical work, follow the disconnection procedure outlined in your owner’s manual, as EVs can have specific shutdown sequences.
- Use the fuse puller tool, often built into the fuse box cover, rather than metal tools that could cause sparking.
- Never replace a low-voltage fuse with one of a higher amperage rating than specified, as this can damage wiring or create a fire hazard.
- If you suspect an issue with the high-voltage system, charging components, or battery management system, do not attempt DIY repairs, these require a qualified EV technician with proper safety training and equipment.
Checking and Replacing Fuses in Ford Focus Electric (EU)
If electrical components in the vehicle are not working, a fuse may have blown. Blown fuses are identified by a broken wire within the fuse. Check the appropriate fuses before replacing any electrical components.
Location of Fuse Boxes
Passenger Compartment Fuse Box:
- Pinch the retaining clips to release the cover.
- Lower the fuse box cover and pull it toward you.
Electric Motor Compartment Fuse Box:
This fuse box is located in the engine compartment. Lift the release lever at the rear of the cover to remove it.
This fuse box contains several high current fuses that protect your vehicle’s main electrical systems from overloads. If the 12 volt battery is disconnected and reconnected, some features need to be reset.
Pre-Fuse Box
Your vehicle has a pre-fuse box located in the electric motor compartment on the front of the 12 volt battery box. It is connected to the 12 volt battery positive terminal. This fuse box contains several high current fuses. If replacement of these high current fuses is required, contact an authorized dealer.

Conclusion
Understanding the fuse box and relay locations on your 2013–2017 Ford Focus Electric helps you handle routine low-voltage electrical issues, such as interior lighting or wiper problems, with confidence. However, because this is an electric vehicle, it’s crucial to recognize the boundary between standard fuse maintenance and the sealed high-voltage system that powers the drivetrain.
Always handle low-voltage fuses and relays with care, confirm amperage ratings before replacing any component, and use the printed diagram to correctly identify each part. For anything related to the high-voltage battery, charging system, or drive components, always consult a qualified Ford EV technician to ensure your safety and avoid damaging critical systems.
