Nissan Almera Classic B10 is a popular sedan that is still in use on the roads of the CIS due to its reliability and ease of maintenance. However, even in such a proven model, fuses periodically blow, which can lead to failure of electrical equipment: from headlights to on-board computers. Unlike modern cars with digital control units, everything here is simpler - but without a diagram, it can be difficult to understand the purpose of each fuse.

In this article you will find full fuse diagram for Almera Classic B10 (including restyled versions 2006–2012), their location in the cabin and under the hood, as well as step-by-step replacement instructions taking into account typical mistakes. We will also look at how to identify a blown fuse without a tester and what to do if the problem does not go away after replacement.

Where are the fuse boxes located in Nissan Almera Classic B10

B Almera Classic B10 fuses are distributed according to two main blocks:

  • 🚗 Salon block — located to the left of the steering column, under the plastic cover. Access to it opens after turning three clamps.
  • 🔧 Engine compartment block — located next to the battery, in a plastic box with a black lid. High current fuses are located here (for example, for the cooling fan or starter).

Important: some trim levels (for example, with air conditioning or ABS) may have additional relays, which are installed separately. We will also look at their diagrams below.

Before you begin your search, make sure that the vehicle muted, and the key is removed from the ignition switch. This will prevent a short circuit from accidentally touching the contacts.

Interior fuse box diagram: decoding by numbers

The interior block contains fuses low and medium current (from 5 to 30 A), responsible for lighting, audio system, instrument panel and other comfort systems. Below is a table with a breakdown for the standard configuration Almera Classic B10 (pre-restyling and restyling 2008–2012).

Number Current (A) Purpose Notes
1 10 Side light bulbs (left side) Often burns out when installing LEDs
5 15 Engine control unit (ECU) It is prohibited to replace with a fuse of a higher rating!
10 7.5 Cigarette lighter Burns out when connecting powerful devices (for example, compressors)
15 20 Heater fan Check the resistance of the fan motor if combustion occurs frequently.
20 10 Audio system May burn out if the radio is connected incorrectly

A complete diagram for your configuration can be found at back side of the block cover — the current markings are usually applied there. If the inscriptions are erased, refer to the color of the fuse (for example, 10A - red, 15A - blue).

⚠️ Attention: fuse No.5 (15A, ECU) - critical. Replacing it with a more powerful one (for example, 20A) can lead to damage to the engine control unit and expensive repairs.

Engine compartment: high current fuses

In the engine compartment Almera Classic B10 located power fuses (from 30 to 100 A), as well as relays of main systems. This block is responsible for:

  • ⚡ Starter and generator (fuses 60–80 A).
  • 🔥 Cooling fan (40 A) - often burns out when the fan jams.
  • 💡 Headlights (15–20 A for each lamp).
  • 🔋 ABS and ESP (if installed).

The special feature of this block is presence of fuse links (fusable links), which look like wires, but act as fuses. Replacing them requires soldering or special terminals.

Relay location in the engine compartment:

  • 🔄 R1 — cooling fan relay.
  • 🔄 R3 — fuel pump relay (if there is a malfunction, the engine will not start).
  • 🔄 R5 — starter relay (clicks, but does not turn).
⚠️ Attention: If after replacing the fuse R3 (fuel pump) The car still won't start, check fuse No. 30 in the cabin block — he is responsible for powering the relay.
How to distinguish a fuse link from a regular wire?

The fuse link is thinner than standard wires and has transparent insulation, inside of which the metal thread is visible. If it burns out, the thread breaks and the insulation can melt. Do not confuse it with mass wires - they are thicker and do not have thinning.

How to identify a blown fuse without a tester

If you don't have a multimeter at hand, you can identify a blown fuse visually or using the simplest methods:

  1. Light inspection: Place the fuse close to the light source. If the metal thread inside is torn or melted, it is faulty.
  2. "Ringing" with a light bulb: Take a 12V light bulb with two wires. Connect one wire to mass, and the second one in turn to the fuse contacts. If the light does not light up, the fuse has blown.
  3. Replacing with a known good one: Take a fuse of the same rating from another circuit (for example, from the cigarette lighter) and install it in the place of the suspect one. If the device works, the problem has been found.

Important: do not use for testing wire jumpers - this can lead to a short circuit and fire in the wiring!

If the fuse blows again after replacement, this indicates short circuit in the circuit. In this case it is necessary:

  • 🔍 Check the wiring for exposed wires or melted insulation.
  • 🛠️ Disable consumers connected to this circuit (for example, a radio or additional LEDs).
  • 📊 Test the circuit with a multimeter in Ω (resistance).
💡

If the fuse blows when the headlights are turned on, check the incandescent bulbs - often the cause is a short in the socket or a burnt-out coil that creates a surge in current.

Typical problems with fuses in Almera Classic B10

Owners Almera Classic B10 often encounter several recurrent problemsrelated to fuses:

  1. Cigarette lighter fuse blown (10A, No. 10):

    Reason: connecting powerful devices (for example, car vacuum cleaners or compressors). The solution is to use a power strip with its own fuse or connect directly to the battery through an additional fuse.

  2. Frequent blowing of the heater fan fuse (20A, No. 15):

    Reason: worn fan motor brushes or jammed bearing. The solution is to disassemble the heater unit and clean or replace the motor.

  3. ABS fuse (10A, No. 25) burns out when driving over uneven surfaces:

    Reason: damage to the wiring of the ABS sensors or oxidation of the contacts. The solution is to check the sensor circuit and clean the connectors.

If the problem persists, don't stop at replacing the fuse - look for the root cause. For example, a fuse constantly blowing №5 (ECU) may indicate a malfunction of the oxygen sensor or a breakdown in the high-voltage ignition circuits.

💡

Before replacing a fuse, always check the voltage in the circuit with a multimeter. If after removing the fuse there is still voltage on its contacts, there is a short circuit in the circuit!

Step-by-step instructions for replacing the fuse

Replacing the fuse in Nissan Almera Classic B10 takes no more than 5 minutes, but requires care. Follow the algorithm:

  1. Preparation:

    Turn off the ignition, remove the key and open the hood (if you are working with the engine compartment). For the interior unit, just open the lid.

  2. Extract:

    In the cabin unit use plastic tweezers (usually attached to the block cover). In the engine compartment, the fuses are removed by hand (but it is better to wear gloves).

  3. Check:

    Inspect the fuse for light or check the circuit with a multimeter (mode 200Ω). The resistance of a good fuse should be close to 0Ω.

  4. Installing a new one:

    Insert fuse same denomination. Do not use bugs or higher power fuses!

  5. Testing:

    Turn on the ignition and check the operation of the circuit. If the fuse blows again, look for a short circuit.

If the fuse is stuck to the contacts and cannot be removed, do not use force - gently shake it with pliers or treat the contacts WD-40.

⚠️ Attention: When replacing fuses in the engine compartment disconnect the negative terminal of the battery. This will prevent accidental shorting when the tool touches metal parts of the body.

Additional relays and fuses in Almera Classic B10

In addition to the main blocks, Almera Classic B10 may be present additional relays and fuses, depending on the configuration:

  • 🔦 Fog lights: fuse 10A and the relays are located separately, next to the light control unit.
  • ❄️ Air conditioning: fuse 10A and the compressor relay are located in the engine compartment (marked AC).
  • 🚨 Alarm: In non-standard systems, the fuse can be located under the dashboard or in the trunk.

For the exact location of additional items, check with electrical circuit of your modification. In restyled versions (2008–2012), the location of the air conditioning relay may differ.

If you installed additional equipment (for example, xenon or sound amplifier), check if they are connected through standard fuses. Often this is what causes their frequent combustion.

Where can I look for a diagram for my configuration?

The official diagram can be found in the instruction manual (section "Electrical equipment"). If you don't have the book, download the PDF version for your VIN on the website Nissan TechInfo (registration required). An alternative is owner forums (for example, Almera-Classic.ru), where scans of the diagrams are posted.

FAQ: Frequently asked questions about fuses Nissan Almera Classic B10

Is it possible to replace the fuse with a more powerful one if it constantly burns out?

No! Increasing the fuse rating may result in wiring fire or failure of expensive components (for example, ECU). If the fuse blows repeatedly, look for the cause - usually a short circuit or a faulty consumer (for example, a fan motor).

Where can I find the fuse for the cigarette lighter if it doesn't work?

This is a fuse in the interior unit No. 10 (7.5A or 10A). If the cigarette lighter does not work after replacement, check cigarette lighter socket - often the central contact burns out there.

Why don't the headlights turn on after replacing the fuse?

Possible reasons:

  1. The lamp in the headlight has burned out.
  2. The headlight relay is faulty (in the engine compartment).
  3. The contacts in the fuse box have oxidized.
  4. The problem is light switch (steering column lever).

Which fuse controls the starter?

Responsible for the starter fuse link in the engine compartment (usually 80A) and relay R5. If the starter does not turn, but the relay clicks, also check power fuse on the positive terminal of the battery (sometimes it is hidden under a plastic cover).

Can fuses from other cars be used?

Yes, if they match denomination and type. B Almera Classic B10 standard blade fuses are used (Mini Blade). The main thing is not to use “circuit breakers” (self-resetting fuses) in circuits where they are not provided (for example, in the ECU).
