<em>Nissan Almera Classic</em>fuse box diagram: location, purpose and replacement

Nissan Almera Classic (internal designation B10) - one of the most popular sedans in the budget segment, released on the basis of the platform Renault-Nissan B0. Despite the simplicity of the design, the electrical circuit of the car requires attention, especially when it comes to fuses. The operation of everything depends on their serviceability - from the headlights to the on-board computer.

In this article you will find complete fuse box diagram with a decoding of each element, you will learn where the mounting block is located in the cabin, how to correctly diagnose faults and replace a blown fuse without the risk of damaging the electronics. We will also analyze the typical mistakes of owners and give recommendations on the selection of spare parts.

Where is the fuse box located in Nissan Almera Classic?

B Almera Classic provided two main fuse boxes:

• 🔧 Main mounting block — located in the cabin, under the instrument panel on the driver’s side. To access it, you need to open the cover, which is secured with two latches.
• ⚡ Additional relay block — located in the engine compartment, next to the battery (may be absent in some modifications).

Most in demand among owners salon unit, since he is responsible for the main consumers: lighting, audio system, power windows, etc. The block cover is usually marked with a diagram, but over the years of use the inscriptions can be erased - so below we will provide the current decoding.

⚠️ Attention: Do not confuse the fuse box with the relay box! Relay in Almera Classic located separately (most often under the hood or behind the glove compartment) and are responsible for highly loaded circuits, for example, the starter or cooling fan.

To get to the cabin unit:

1. Open the driver's door and crouch down to see the bottom of the instrument panel.
2. Find a plastic cap approximately 15×10 cm with the inscription FUSE or a fuse icon.
3. Gently pry the cover open with a screwdriver or flat object (do not use excessive force to avoid breaking the latches).

How to check and replace a fuse: step-by-step instructions

If in your Almera Classic If any electrical circuit stops working (for example, the headlights don’t light up or the stove doesn’t work), the first thing you should do is check the fuses. For this you will need:

• 🔦 Flashlight (for illuminating the block).
• 🛠️ Tweezers (usually included with the car).
• 🔋 A set of spare fuses (ratings: 5, 10, 15, 20, 25 A).

Algorithm of actions:

1. Turn off the ignition and remove the key from the lock.
2. Remove the fuse box cover (as described above).
3. Find the fuse responsible for the faulty circuit (use the diagram from the previous section).
4. Remove the fuse with tweezers and inspect it for thread break or melting of the housing.
5. If the fuse is blown, replace it with a new one same denomination (color and markings must match!).
6. Turn on the ignition and check the operation of the circuit.

⚠️ Attention: Never install a fuse with large denominationthan indicated in the diagram! This may lead to fire in the wiring or failure of expensive components (for example, an engine control unit).

If after replacement the fuse blows again, this indicates short circuit in the chain. In this case, you need to contact an auto electrician to diagnose the wiring.

Typical problems with fuses in Almera Classic and their solutions

Owners Nissan Almera Classic often encounter repeated faults related to fuses. Let's look at the most common cases:

1. Frequently blown cigarette lighter fuse (F10)

Reasons:

• 🔌 Use of powerful devices (compressors, inverters) without adapters.
• 🔥 Short circuit in the cigarette lighter socket due to liquid or debris.

Solution: Disassemble the cigarette lighter socket, clean the contacts and check the integrity of the wiring. If the problem persists, replace the entire socket.

2. Power window fuse (F7) burns out when the glass moves

Reason: Mechanical jamming of the window regulator (most often due to icing or foreign objects).

Solution: Remove the door trim, check the mechanism for free movement and lubricate the guides. If the window lift motor is worn out, replacement is required.

3. Lighting fuses (F1, F2, F15) light up after replacing lamps with LEDs

Reason: LED lamps can create surge currents when turned on that standard fuses are not designed to handle.

Solution: Install load resistors or go back to halogen lamps. Also check the polarity of the LED connections.

What to do if the fuse is intact, but the circuit does not work?

In this case, the problem may lie in the relay, broken wiring, or a malfunction of the device itself (for example, a light bulb or motor). For diagnostics, use a multimeter in dial mode. If there is voltage at the fuse, but not at the consumer, look for an open circuit between them.

Choosing fuses: which ones to buy for Almera Classic?

There are many brands on the market that produce car fuses. For Nissan Almera Classic standard ones fit blade fuses type ATO/ATC (size: 19×5×18.5 mm). Main selection criteria:

• 🔹 Denomination - must strictly comply with the scheme (for example, 10A for dimensions, 20A for window regulators).
• 🔹 Housing material — fuses with a transparent body are preferred (it is convenient to check the integrity of the thread).
• 🔹 Brand - reliable manufacturers: Bussmann, Littlefuse, Hella, Bosch.

Avoid cheap fuses of unknown brands - they may have an inaccurate rating or poor quality contacts, which will lead to heating and melting of the block.

Brand	Series	Pros	Cons
Littlefuse	ATM	High reliability, accurate value	Price is above average
Bussmann	ATC	Vibration resistant, long service life	Difficult to find in small stores
Nevsky	Standard	Low price, widely distributed	The quality of the control thread is worse than imported ones

⚠️ Attention: On sale there are so-called "bugs" - homemade jumpers instead of fuses. Their use strictly prohibited, since this is a direct road to a fire in the car!

Fault diagnosis: when is it not the fuse that is to blame?

The lack of power in a circuit is not always associated with a fuse. If the problem persists after replacement, check the following items:

• 🔌 Relay - in Almera Classic relays are responsible for highly loaded circuits (for example, a cooling fan or fuel pump). Test the relay with a multimeter or replace it with a known good one.
• 🔋 Wiring — breaks or oxidation of contacts often occur in places where the harnesses are bent (for example, at the doors or under the hood).
• 📶 Control unit - if several circuits do not work simultaneously, a failure may occur ECU (electronic control unit).

To check the relay:

1. Remove the relay from its socket (usually located near the fuse box or under the hood).
2. Test the relay winding with a multimeter - the resistance should be within 50–120 Ohm.
3. Apply voltage 12V to the control contacts - a clicking sound should be heard (contacts closing).

If you are not confident in your skills, it is better to contact a specialist. For example, diagnosing an engine control unit requires special equipment (diagnostic scanner) and knowledge.

Modifications and improvements: what do you need to know?

Many owners Nissan Almera Classic install additional equipment: alarms, multimedia systems, heated seats, etc. It is important to remember:

• 🔌 Each new device must be connected via a separate fuse (the rating is calculated based on the consumer's power).
• 🔋 Don't overload the stock chains - for example, connecting a powerful subwoofer to the cigarette lighter wires will lead to burnout F10.
• 📶 Use a relay for controlling highly loaded devices (for example, additional headlights).

Example of correct connection:

[Аккумулятор] → [Предохранитель 30A] → [Реле] → [Потребитель (например, лебёдка)]

If you install car alarm, be sure to connect it through a separate fuse and relay, and not directly to the standard circuits. This will protect against malfunctions of the on-board electronics.

FAQ: Frequently asked questions about fuses Nissan Almera Classic

Is it possible to replace a fuse with a higher rating if it blows frequently?

No, it's dangerous! Increasing the rating may result in melted wiring or fire. If the fuse blows frequently, look for the cause - usually it is short circuit or circuit overload (for example, due to a faulty window lift motor).

Where is the fuse for the fuel pump?

B Almera Classic The fuel pump fuse is F20 (face value 15A), and the relay is located next to the fuse box under the hood. If the car does not start and you cannot hear the pump running, check this fuse first.

Why after replacing the fuse F10 cigarette lighter not working?

Possible reasons:

• The cigarette lighter socket is burnt out (check the voltage with a multimeter).
• The contacts in the fuse box have oxidized (clean them with alcohol).
• Broken wire between the unit and the cigarette lighter.

Which fuse controls the instrument panel lights?

The fuse controls the panel illumination F2 (10A). If the backlight does not work after replacing it, check the lamps in the dashboard or the lighting control unit.

Can fuses from other cars be used?

Yes, if they meet the standard ATO/ATC and have the required denomination. However, it is better to choose fuses from proven brands (Littlefuse, Bussmann), since cheap analogues may have inaccurate characteristics.
