Some classify the Nissan Almera Classic as the third generation Almera, others as the restyled model of the 2nd generation. Both options have their own truth. Since it was created on the platform of the previous generation, but has a modified body marked B10 and a modified suspension system. Developed specifically for Russia. Years of manufacture: 2006, 2007, 2008, 2009, 2010, 2011, 2012 and 2013. We suggest that you familiarize yourself with the description of the fuse and relay blocks of the Nissan Almera Classic, as well as their photographs, diagrams and decoding of the elements.

Device and malfunctions
Before proceeding directly to the repair itself, it is advisable to understand the structure of the device being repaired. Otherwise, some problems and “inconvenient” moments may arise during a relatively simple operation.
A block is a system of fuses combined into one unit, each of which is built into the electrical circuit of a specific device. This element is necessary to protect the circuit from a number of unfavorable processes, including potential ignition of the wiring due to a short circuit. Such unpleasant phenomena occur due to excess current flow in the electrical circuit, which is associated, for example, with a malfunction of the device or wires. The fuse has a lower maximum current threshold, so it blows out first and immediately de-energizes the entire system. As you can see, a knot of this type is very useful and requires due attention.
Due to the specifics of its operation, a block or individual fuse can fail for a number of different reasons:
- malfunction of any device;
- electrical short circuit;
- too high current flowing into the system (often happens when the generator breaks down);
- incorrectly carried out repairs to the electrical unit of the car;
- manufacturing defect;
- excessive wear.
Having considered the above potential problems that caused the fuse to blow, we can conclude that sometimes it will be necessary to correct faults in some other components of the Nissan Almera. Of course, if you have a desire to achieve normal functioning of the car's electrical system and safe operation.

Location and electrical diagram
In the Nissan Almera classic n16 there are several fuse blocks responsible for the operation of electrical equipment.
One of them is located in the car interior, the other two are in the engine compartment. On the front side of the power supply unit, located in the vehicle interior, there are several fuses (hereinafter referred to as fuses) and relays.
On the other side of the device there are three more main relays.
There are two power supplies in the engine compartment. One of them contains relays, and the other contains only fusible devices. Below are diagrams of all three blocks, as well as a description of the fuses in them.
PSU in the cabin
What are these elements responsible for? Below is a table with the designation of each PP.
You may also have noticed several relays whose purpose is not described in the table. They should be highlighted separately, since the relays are designed for more powerful voltage consumers.
| Number | Purpose |
| R1 | This component ensures the functionality of the headlight lamps, that is, it is responsible for both low and high beam. |
| R2 | The second component by number ensures the functioning of the throttle valve. If it fails, the operation of the car will be incorrect or impossible. |
| R3 | Responsible for the operation of electric windows. |
| R4 | Ensures the functionality of the rear fog lamps. |
As for the device number 22, which is responsible for the functionality of the cigarette lighter. In Nissan Almera classic n16 models, cigarette lighter failure is a common problem. It can even be called a disease, since many motorists encounter this malfunction.
Correct replacement of fuse links
Before replacing fuses, disconnect the negative terminal of the battery.
Before replacing the Almera Classic protective devices, you will need to dismantle the old element and make sure it is unsuitable. For this, special plastic tongs are used. In most cases, damage to the fuse link is visible to the naked eye. In rare cases, a continuity test using a multimeter is required. You will also need to purchase a new fuse or relay. It is necessary to select the appropriate rated current of the product. It is written on the component itself, or determined by the color scheme. Replacement is carried out in the following sequence:
A poor quality fuse may cause a fire.
- To check the quality of the new protective element, you should connect the fuse link directly through the battery using two wires. It must withstand the load without showing signs of melting;
- It is necessary to establish and eliminate the cause of burnout of protective devices. Otherwise, the new element will burn out or the electrical equipment will burn out;
- Disconnect the negative terminal of the battery;
- Remove the burnt out protective element and install a new one;
- Connect the battery terminal and check the functionality of the equipment.
Purpose, types and colors of electrical fuses
"Nissan Almera Classic": technical characteristics and description of the car
Almera G15 fuses are a protective element of various electrical equipment from the following phenomena:
- short circuits;
- current overloads.
Their circuit can be made in one, two or three blocks. Moreover, each of them is responsible for the operability of the equipment complex, and a separate element is responsible for the protection of a specific device.
The following types of fuses are distinguished:
Plug fuses
Plug-in - the most common, consist of two plugs, between which there is a fuse-link for a certain amount of current. It is closed with a plastic casing. When the maximum value of the current flowing through the insert is exceeded, it burns out.
Bimetallic - in the specified type of fuses, the fuse-link is replaced with bimetallic plates with silver-plated contacts that fit tightly to each other. If an abnormal mode occurs, the plates heat up and open. Their further contact will occur after the metal has cooled.
Plug and bimetallic fuses with spring
Spring bimetallic - the principle of operation is identical to the previous type. The difference is that the bimetallic plates do not return to their original position on their own. This is achieved by introducing an additional spring into the design, which holds the plate in the off position. To restore the electrical circuit, you will need to press a button that will release the spring.
Fuses are produced with different current ratings. At the same time, manufacturers give each denomination a specific color. In most cases, the following colors are used:
- black – 1A;
- gray – 2A;
- purple – 3A;
- brown-yellow – 5A;
- dark brown – 7.5A;
- red – 10A;
- blue – 15A;
- yellow – 20A;
- white – 25A;
- green – 30A;
- orange – 40A;
- blue - 60A;
- brown – 70A;
- light yellow – 80A;
- lilac – 100A.
Color shades may vary
Recommendations for diagnosing electrical equipment
The main causes of malfunctions in the operation of car electrics: contact failures in circuits, oxidation of terminals on connectors, failure of relays and blown fuses or fuse links. Symptoms of violations can be different - from short circuits due to insulation damage to the shutdown of devices, components (one or several at once) and failure to start the engine. Serious problems in an electrical circuit with powerful consumers can cause the wiring to ignite and lead to a fire, so when even minor faults are detected, it is important to diagnose the entire electrical circuit.
The search for the cause of the malfunction begins with the identification of working elements by the method of exclusion until the detection of a non-working unit (relay or blown fuse). If several consumers do not work, then contact to ground may be broken, since they can all be connected through one circuit.
To identify problems in circuits, special diagnostic equipment is used: a voltmeter, a tester, a set of connecting wires with alligator clip terminals, or a probe with an indicator and a 12 V test light. Before checking, carefully study the circuit and test for the presence of voltage, starting from the source power supply to the fuse block connector, first checking the integrity of the fuse links.
Nissan Almera fuses >
The electrical circuit of the Nissan Almera Classic is arranged as a single-wire circuit: the positive terminal of all energy consumers is connected to the body, the negative terminal is connected to ground. The components and mechanisms are powered while the vehicle is moving from the generator, and when the engine is not running - from the battery.
All circuit circuits are controlled through mounting blocks with relays and fuses, which are designed to protect against short circuits and power surges when the ignition system is turned on.
In total, three blocks are installed on the Almera Classic, each of which is responsible for the operation of a specific circuit and provides power to the elements using a multi-wire circuit.
DISASSEMBLY OF A BROKEN ELEMENT
It’s another matter if after such an event the energy source has not been restored. In this case, it will be necessary to disassemble the element itself. First, you can do a preliminary check:
- You should get to the back of the nest.
- Remove the connector.
- Connect the light bulb.
- Turn the key to ACC position.
If the light comes on, dismantling will be necessary. In this regard, a reasonable question arises: how to remove the cigarette lighter on a Nissan Almera Classic?
