<em>Nissan Almera Classic</em>starter relay: diagnostics, malfunctions and replacement

Nissan Almera Classic (B10) is a popular sedan known for its reliability, but even it has electrical problems over time. One of the most common problems is failure starter relay, due to which the engine stops starting or does so with difficulty. In this article we will look at how to independently diagnose a malfunction, select a replacement and install a new relay without contacting service.

Starter Almera Classic works in tandem with a pull-in relay and an additional switching relay (often called the "starter relay"), which is located in the mounting block. Its task is to protect the ignition switch contacts from high currents and ensure stable operation of the starter. If this small but important element fails, the driver is faced with problems starting the engine, although the battery and the starter itself may be fully operational.

Where is the starter relay located on Nissan Almera Classic

B Nissan Almera Classic (2006–2012) starter relay located in fuse and relay mounting block, which is located inside the car, to the left of the steering column. To access it, you must:

1. Open the driver's door and remove decorative cover fuse box (it is secured with latches).
2. On the inside of the cover there is a diagram of the location of the relays and fuses.
3. The starter relay is marked as Starter Relay or R17 (depending on the year of manufacture).

Externally, the relay is a standard rectangular block with 4 contacts (numbers 85, 86, 87, 30) and markings 12V 40A. It is important not to confuse it with main relay (often located nearby) or the fuel pump relay.

How to distinguish a starter relay from others?

On Almera Classic The starter relay is usually black or dark gray with white markings. The main relay (ECU Relay) is green or blue. The Fuel Pump Relay may be red or orange. If in doubt, check the diagram on the block cover or check by part number: the original starter relay has a part number 25230-4M000 or 25230-4M00A.

If there is no diagram on the block cover (for example, it has been erased), you can refer to arrangement in rows:

• 🔋 In the first row (closer to the windshield) there are usually relays cooling fan And air conditioner.
• 🚗 In the second row - relay starter, fuel pump And main relay.
• ⚡ In the third - relay low/high beam And heated rear window.

Signs of a bad starter relay

Problems with the starter relay on Almera Classic often disguised as other malfunctions: a flat battery, a broken starter, or even problems with the alarm. Here exact symptoms, pointing specifically to the relay:

• 🔊 Starter clicks without cranking: When you turn the key, you hear a single or multiple click, but the starter does not turn the engine. This is a sign that the relay is triggered, but the contacts 87 And 30 do not close properly.
• 🔄 The starter works "every time": Sometimes the engine starts the first time, and sometimes it takes several tries. This speaks of burning of contacts inside the relay.
• 🚫 No response when turning the key: when the key is turned to the "Start" position, nothing happens - no clicks, no startup Attempts. Perhaps the relay has completely failed or is not receiving a control signal.
• 🔥 Burning smell from under the panel: If the relay overheats, a characteristic smell of burnt plastic may appear. This is a critical sign - further exploitation is fraught short circuit.

It is important to distinguish a relay malfunction from problems with starter solenoid relay (which is located directly on the starter under the hood). If you hear when you turn the key loud metallic click under the hood, but the starter does not turn - the retractor is to blame. If the click is quiet and comes from inside the car, the problem is in the relay in the mounting block.

⚠️ Attention: If you try to start the engine dashboard goes dark or you hear a crackling sound in the area of the mounting block, immediately disconnect the battery! These are the signs short circuit in the relay circuit, which may cause a fire.

How to check the starter relay with and without a multimeter

Before buying a new relay, you should make sure that the old one is really faulty. There are two ways to check for this: without tools (by replacement method) and using multimeter.

Method 1: Check by replacement (without tools)

The simplest method is to temporarily install a known good relay. A relay from fuel pump or cooling fan (they are identical in design). Algorithm:

Make sure the car is in neutral and the handbrake is on

Open the mounting block and locate the starter relay (R17)

Carefully remove the starter relay and replace it with the fuel pump relay (R10)

Try to start the engine - if the starter works, the problem is in the relay

Put the relay back in place and buy a new one to replace it -->

If after replacement the starter starts working, it means the old relay is faulty. If the problem persists, look for the cause in wiring, ignition switch or the starter itself.

Method 2: Check with a multimeter

For accurate diagnostics you will need a multimeter in calls (or resistance measurements). Procedure:

1. Remove the relay from the mounting block.
2. Connect negative probe multimeter to contact 85 (mass), and positive - to 86 (control plus).
3. Serve 12V to contacts 85 And 86 (possible from battery via wires). At the same time it should be heard distinct clicking sound - this triggers the electromagnet inside the relay.
4. Check resistance between contacts 30 And 87:
   • 🔌 Without voltage supply on 85-86: there must be resistance endless (open contacts).
   • 🔌 When supplied 12V on 85-86: there must be resistance close to 0 ohm (closed contacts).

If, when voltage is applied, the contacts 30-87 do not close or the resistance “floats” - the relay is faulty. Also inspect the case for reflows or cracks.

Selecting a starter relay: original vs analogues

Original starter relay for Nissan Almera Classic has an article number 25230-4M000 or 25230-4M00A. Its average price in official dealers is 1,200–1,800 rubles. However, you can save money by choosing a high-quality analogue. The main thing is to pay attention to switching current (must be at least 40A) and contact type (must match the original).

Manufacturer	Article	Price, rub.	Features
Nissan (original)	25230-4M000	1 500–1 800	12 month warranty, fully compatible
Bosch	0 332 014 150	800–1 100	High quality contacts, long service life
Hella	4RA 003 439-381	900–1 200	Reinforced insulation, suitable for extreme temperatures
Febi Bilstein	25230	600–900	Budget option, average quality
ERA	550105	400–700	Low price, but frequent complaints about reliability

When choosing an analogue, pay attention to:

• 🔧 Contact material: it's better if they are from silver or copper, and not from a cheap alloy.
• 📦 Packaging: original parts and high-quality analogues have holograms, protective stickers and clear markings.
• 🛡️ Guarantee: reliable manufacturers (for example, Bosch or Hella) provide a guarantee of at least 1 year.

⚠️ Attention: Be careful with cheap unbranded relays (like those from AliExpress). They often have poor soldering quality and may cause fire due to overheating of contacts. It’s better to overpay for a trusted brand than to risk the safety of your car.

Step-by-step instructions for replacing the starter relay

Replacing the starter relay with Nissan Almera Classic takes no more than 10 minutes and does not require special tools. You only need new relay and, if necessary, flat blade screwdriver (to remove the fuse box cover).

New relay (original or analogue with the article number from the table above)

Flat blade screwdriver (if the unit cover is tight)

Flashlight (for easier inspection of contacts)

Gloves (optional to avoid leaving fingerprints on contacts) -->

Procedure:

1. Turn off the ignition and remove the key. Make sure all electrical appliances (headlights, radio) are turned off.
2. Open mounting block cover fuses and relays (to the left of the steering column). If the cover cannot be removed by hand, carefully pry it off with a screwdriver.
3. Locate the starter relay (R17 or Starter Relay). For convenience, you can take a photo of the relay location on your phone.
4. Carefully grab the relay and pull it up. It should come out without effort (if it is tight, do not pull - check for latches).
5. Install new relay replace the old one, making sure that the contacts match. Press all the way and you should hear a click.
6. Close the block cover and check the operation of the starter.

If the starter does not work after replacement, check:

• 🔌 Starter fuse (usually F10 on 10A in the same block).
• 🔋 Battery charge - if the voltage is lower 11.5V, the starter will not work.
• 🔧 Contact status in the mounting block - they can be oxidized.

Common mistakes when diagnosing and replacing

Even experienced car owners sometimes make mistakes when working with the starter relay. Here are the most common ones:

• 🔧 Confused starter relay with fuel pump relay. They look similar, but have different current characteristics. If you put the fuel pump relay in place of the starter relay, it will quickly burn out.
• 🔌 Don't check the fuse. Often the problem lies not in the relay, but in a blown fuse F10 (10A), which is responsible for the starter control circuit.
• 🛠️ Use incompatible analogues. For example, a relay from VAZ or Toyota may not fit contact size or switching current.
• 🔥 Ignore signs of short circuit. If the relay gets hot or smells burning, replacing it is only a temporary solution. Need to check wiring for a short circuit.

Another common mistake is checking the relay without taking into account its “past life”. For example, if the relay has already been used or was stored in a damp place, its contacts may have oxidized. In this case, even a seemingly serviceable relay will work unstably.

⚠️ Attention: If after replacing the starter relay other electrical appliances stopped working (for example, headlights or power windows), you most likely have the relays mixed up. Return everything to its original place immediately to avoid blown fuses.

Preventing problems with the starter relay

To keep the starter relay on Nissan Almera Classic last longer, follow simple recommendations:

• 🔋 Monitor your battery status. If the battery is discharged, the starter takes longer to crank the engine, which increases the load on the relay.
• 🔌 Clean contacts periodically in the mounting block. Oxidation impairs conductivity and causes the relay to overheat.
• 🚗 Do not hold the key in the "Start" position for more than 5 seconds. If the engine does not start, pause for 10-15 seconds before trying again.
• 🛡️ Use quality spare parts. Cheap relays often have weak contacts that quickly burn out.

Also useful once a year check voltage on the relay contacts when the engine starts. To do this:

1. Connect the multimeter in mode DC 20V to contacts 85 (mass) and 86 (management).
2. Have an assistant turn the key to the "Start" position.
3. The voltage should be 11.5–12V. If it is lower, the problem is wiring or ignition switch.

FAQ: Frequently asked questions about the Almera Classic starter relay

Is it possible to drive with a faulty starter relay?

Technically it is possible, but it is fraught with consequences:

• If the relay doesn't work, you will not be able to start the car without a “push” or towing.
• If the relay stuck closed, the starter will operate continuously, which will cause it to overheating and breakdown.
• In both cases there is a risk drain the battery or burn the wiring.

We recommend replacing the relay at the first sign of trouble.

What is the difference between a starter relay and a solenoid relay?

These are two different devices:

• Starter relay (in the mounting block) - manager. It closes the circuit upon command from the ignition switch.
• Solenoid relay (on the starter housing) - executive. It engages the starter gear with the flywheel and completes the power circuit.

If it clicks in the salon — the problem is in the starter relay. If it clicks under the hood - in the retractor.

Which relay can be used instead of the original one?

Analogs with the following parameters are suitable:

• Switching current: not less than 40A.
• Voltage: 12V.
• Contact type: standard 4-pin (85, 86, 87, 30).

From trusted brands: Bosch 0 332 014 150, Hella 4RA 003 439-381, Febi 25230.

Why does a new relay burn out quickly?

Reasons:

• 🔌 Short circuit in the starter circuit (check the wiring from the relay to the starter).
• 🔋 Weak battery - if the voltage is lower 11V, the relay is overloaded.
• 🛠️ Poor contact in the mounting block (oxidation or loose terminals).
• 🔥 Poor quality relay (especially Chinese "no-name" variants).

Before installing a new relay Be sure to check the circuit with a multimeter!

Can the starter relay be repaired?

Theoretically yes, but not recommended. Relay is non-removable element with a sealed housing. If you take it apart, then:

• Can be cleaned pins 87 and 30 (they often burn).
• But restore tightness And reliability not possible after renovation.
• Cost of a new relay (600–1,500 rub.) is comparable to the risks (fire, repeated breakdown).

It is better to buy a new relay from a trusted manufacturer.
