Nissan Almera G15 is a popular sedan known for its reliability, but even it has problems with electrical equipment over time. One of the most common malfunctions 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 the problem, select a high-quality relay and replace it without contacting service.

A faulty relay can manifest itself in different ways: from clicks without cranking the starter to a complete lack of response to turning the key. Many owners Almera G15 they mistakenly blame the battery or the starter itself, wasting time and money on unnecessary checks. Meanwhile, replacing a relay takes less than 30 minutes and costs several times less than repairing a starter. Next is a detailed guide with photos, diagrams and life hacks from experienced auto electricians.

Signs of a faulty starter relay on Almera G15

The starter relay is a small but critical element of the starting system. Its task is to close the circuit between the battery and the starter, providing current up to 200-300 A at the moment of launch. When a relay fails, the symptoms can be both obvious and indirect. Here are typical “bells” that you should pay attention to:

  • 🔊 Clicks without scrolling: when you turn the key, a clear click of the relay is heard, but the starter does not rotate the crankshaft. This indicates burnt contacts inside the relay or a broken winding.
  • 🔄 Multiple activations: The starter jerks several times in a row before the engine starts. The reason is an unstable contact in the relay or its “sticking”.
  • 🔋 No reaction: When turning the key there is no clicking or sound of the starter. The problem may lie in the relay, fuse F30 (10A) or broken wiring.
  • 🔥 Burning smell: if the engine compartment smells like burnt plastic, most likely the relay contacts are burnt due to overheating.

It is important to distinguish a relay malfunction from problems with starter solenoid relay (which is located directly on the starter housing). If, when the relay clicks, the starter still turns, but with difficulty, the retractor is to blame. If there is no click at all or there is one, but the starter is silent - check main starter relay in the mounting block.

⚠️ Attention: On Almera G15 with an automatic transmission, if the starter relay is faulty, starting in the selector position may be blocked P or N. Before diagnosing, check whether the lamp is on P on the instrument panel - if not, the problem may be in the selector switch, and not in the relay.

Where is the starter relay located on Nissan Almera G15?

Unlike many vehicles where the starter relay is mounted directly on the starter or in a separate unit, the Almera G15 it is located in fuse and relay mounting block under the hood. Exact location:

  • 📍 Mounting block: located to the left of the battery, under the plastic cover with the inscription FUSE & RELAY BOX.
  • 🔍 Socket number: Starter relay installed in socket R17 (there is a numbered diagram on the block cover).
  • 🔧 Relay type: standard 4-pin relay with markings 12V 30A (the value may differ among analogues).

To get to the relay, follow these steps:

  1. Open the hood and remove the negative terminal from the battery (required!).
  2. Unhook the two latches on the mounting block cover and remove it.
  3. Locate the relay in the socket R17 (usually it is black or dark gray).
  4. Gently pull the relay up to remove it from its socket.
💡

Before removing the relay, take a photo of its location on your phone - this will help avoid confusion when reinstalling it, especially if you plan to test several relays at the same time.

On some versions Almera G15 (for example, with an engine HR16DE) the starter relay can be duplicated in the interior fuse block (under the dashboard on the driver's side). However, in 90% of cases it is enough to check the relay in the engine compartment.

How to test the starter relay with a multimeter?

Checking the starter relay does not require special skills - it is enough to have a multimeter on hand (or even a simple test) and know the procedure. Below are step-by-step instructions with standard values for Almera G15.

Connect the probes to pins 85 and 86 (winding)|Apply 12V to pins 85 and 86 - you should hear a click|Ring pins 30 and 87 after the click (should be short circuit)|Check the winding resistance (normal: 70-120 ohms)-->

To check, follow these steps:

  1. Visual inspection: Inspect the relay housing for cracks, melting or corrosion of the contacts. If the housing is damaged, the relay must be replaced.
  2. Winding check:
    • Switch the multimeter to resistance measurement mode (200 Ohm).
    • Connect the probes to the contacts 85 And 86 (usually these are the side legs of the relay).
    • Normal winding resistance: 70–120 Ohm. If the device shows 0 (short circuit) or ∞ (break), the relay is faulty.
  3. Functionality check:
    • Connect 12V from battery to contacts 85 And 86 (polarity is not important).
    • You should hear a clear click - this means that the contacts are 30 And 87 closed up.
    • Call contacts 30 And 87 multimeter in “continuity” mode - there should be a short circuit (resistance 0 ohm).
Contacts Normal condition Symptom of malfunction
85–86 (winding) Resistance 70–120 Ohm 0 ohm (KZ) or ∞ (break)
30–87 (power circuit) Open without voltage, closed when supplied 12V on 85–86 Constantly closed or not closed
Relay housing Whole, without cracks or melting Cracks, signs of overheating, contact corrosion

If the relay fails at least one of the tests, it must be replaced. Attempting to repair a relay by soldering contacts is not recommended This is a temporary solution and may result in a short circuit or fire.

Step-by-step replacement of the starter relay with Almera G15

Replacing the starter relay is one of the simplest procedures that even a beginner can handle. The whole process will take no more than 20 minutes if you follow the instructions. You will need:

  • 🔧 Flathead screwdriver (for removing the fuse box cover).
  • 🔋 Multimeter (to test the new relay before installation).
  • 🧤 Gloves (optional, but recommended for protection from dirt).

Sequence of actions:

  1. Disconnect the battery:
    • Remove the negative terminal from the battery (this is mandatory for safety!).
    • If on your Almera G15 If you have an alarm installed, make sure that it will not go off if the power is turned off.
  2. Remove the mounting block cover:
    • Press the two latches on the sides of the cover and pull it up.
    • Under the cover you will see a diagram of the location of the relays and fuses.
  3. Remove the faulty relay:
    • Locate the relay in the socket R17 (see diagram on the cover).
    • Gently pull it up, rocking it slightly from side to side.
  4. Install a new relay:
    • Before installation, test the new relay with a multimeter (see section above).
    • Insert the relay into the socket R17 until it clicks.
  5. Check your work:
    • Connect the battery terminal.
    • Try to start the engine - the starter should fire the first time.
What should I do if the starter does not work after replacing the relay?

If the starter still does not engage after installing the new relay, check:

1. **Fuse F30 (10A)** - it is responsible for the relay control circuit.

2. **Contacts of socket R17** - they may be oxidized or burnt (clean them with alcohol or fine sandpaper).

3. **Wiring from the ignition switch** - if + 12V does not come to pin 85 of the relay when you turn the key, the problem is in the lock or wiring.

4. **Battery** - even if it turns, the voltage may not be enough to operate the relay (check the voltage under load).

If the problem persists after replacing the relay, the reasons may be more serious:

  • 🔌 Broken wiring between the ignition switch and the relay.
  • 🔑 Malfunction of the ignition switch contact group.
  • 🔋 Battery discharge or sulfation (voltage below 11.5V).
💡

If the new relay burns out immediately after installation, the problem lies in a short circuit or a malfunction of the starter (for example, a shorted winding). In this case, diagnostics of the starter and wiring is required.

Common mistakes when replacing a starter relay

Even something as simple as replacing a relay can result in new problems if mistakes are made. Here are the most common mistakes owners make Almera G15:

  • 🔌 Ignoring new relay testing: Many people install the relay “by eye” without checking it with a multimeter. As a result, it turns out that the new relay is also defective.
  • 🔧 Mixed up nests: in the mounting block Almera G15 starter relay (R17) is located next to the fan relay (R18). It's easy to confuse them if you don't look at the diagram.
  • 🔋 Operation without disconnecting the battery: when replacing a live relay, you can burn not only the new relay, but also the engine control unit (ECU).
  • 🧹 Dirt in the nest: If you do not clean the socket contacts R17 from oxidation, the new relay will quickly fail.

Another common mistake is purchasing a relay with inappropriate parameters. For example, some owners install a relay on 20A instead of recommended 30–40A, which leads to its overheating and failure after 1–2 months. Always check the analog table (see section above).

⚠️ Attention: If after replacing the relay the starter starts working “every once in a while”, check engine weight. On Almera G15 The ground contact on the gearbox (under the battery) often oxidizes, which leads to unstable operation of the starter.

Preventing problems with the starter relay

To make the starter relay last longer, just follow a few simple rules:

  • 🔋 Monitor your battery condition:
    • The starter relay suffers from low voltage in the on-board network. If the battery is discharged (voltage below 12.2V), the current through the relay increases, which leads to burning of the contacts.
    • Check the battery voltage periodically and charge it if it drops below 12.4V.
  • 🔌 Clean the contacts of the mounting block:
    • Once a year, remove the fuse box cover and clean the relay and fuse contacts from oxidation (you can use alcohol or a special cleaner Contact Cleaner).
  • 🚗 Avoid lengthy startup attempts:
    • If the engine does not start the first time, do not turn the starter longer. 5–7 seconds. The pause between attempts must be at least 30 seconds, otherwise the relay will overheat.
  • 🛠️ Check the starter at the first sign of trouble:
    • If the starter starts to turn “tightly” or extraneous sounds appear (grinding, squealing), do not delay diagnostics. A worn starter creates increased load on the relay.

If you often drive off-road or in high humidity conditions, it is recommended to treat the contacts of the mounting block dielectric grease (For example, Liqui Moly Electronic-Spray). This will prevent oxidation and corrosion.

💡

On Almera G15 with a mileage of more than 100 thousand km, check the condition of the starter retractor relay every 20–30 thousand km. Its wear directly affects the service life of the main starter relay.

FAQ: Frequently asked questions about the starter relay Nissan Almera G15

Is it possible to drive with a faulty starter relay?

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

  • If the relay is “stuck” in the closed state, the starter will work constantly, which will lead to its overheating and failure.
  • If the relay does not work, you will not be able to start the car without "lighting" or towing.
  • In both cases, the load on the battery increases, which shortens its service life.
Recommendation: Replace the relay at the first sign of trouble.

How to distinguish a faulty starter relay from a problem with the starter?

Do a simple test:

  1. Turn the key to the “start” position and listen:
    • If heard click, but the starter does not turn - the problem is in the starter or battery.
    • If no click - faulty relay, fuse F30 or wiring.
  • Try closing the contacts 30 And 87 on the relay with a screwdriver (with the ignition on). If the starter spins, the relay is faulty.
    • ⚠️ Attention: Contacts can only be closed on a removed relay! Do not do this in the block socket - you risk burning the wiring.

    Which starter relay is better to choose for Almera G15 - original or analogue?

    Depends on budget and goals:

    • Original (25230-4M000): optimal if you plan to drive the car for a long time. Resource - 150–200 thousand km.
    • Bosch/Hella: the best analogues in terms of price/quality ratio. The resource is comparable to the original.
    • Era/Meat & Doria: budget option for temporary replacement. Resource - 30–50 thousand km.
    Advice: If you buy an analogue, take a relay with a current reserve (40A instead of 30A).

    Is it possible to repair the starter relay with your own hands?

    Theoretically yes, but not recommended. Here's why:

    • The relay is a non-separable part. To get to the contacts, you have to break the case.
    • Even if you manage to clean the burnt contacts, they will quickly oxidize again.
    • Do-it-yourself repairs may result in short circuits and fires.
    Exception: if the relay is stuck due to dirt, you can try to clean its contacts with alcohol (without disassembling).

    Where else on the Almera G15 could there be a starter relay, other than the mounting block?

    On most Almera G15 There is one starter relay - in the engine compartment (R17). However, on some versions (for example, with Automatic transmission and the system Nissan Intelligent Key) there may be an additional relay in the interior fuse block (under the dashboard, to the left of the steering wheel). Its function is to block startup in the event of an immobilizer malfunction.
