Nissan Almera Classic - a reliable car, but even it has problems starting the engine over time. One of the most common reasons is a malfunction starter relay. However, finding it is not so easy: depending on the year of manufacture and configuration, the location may differ. In this article we will look at where exactly to look for a relay on Almera Classic (including models B10 And N16), how to check it with a multimeter and what to do if it fails.

Many owners confuse the starter relay with solenoid relay (which is attached directly to the starter) or with engine control system main relay. We'll explain the difference in detail and show you how to avoid getting the details mixed up. You will also learn what symptoms indicate a problem with the relay, and not with the battery or the starter itself.

Difference between starter relay and solenoid relay

Before looking for a relay, it is important to understand exactly what part we are talking about. In the launch system Nissan Almera Classic There are two key elements involved:

  • 🔧 Starter relay — is located in the mounting block and is responsible for supplying voltage to the solenoid relay upon command from the ignition switch.
  • 🔌 Solenoid relay — installed on the starter housing and directly closes the circuit, starting the rotation of the armature.

If the problem is solenoid relay, you will hear characteristic clicks under the hood when you turn the key, but the starter will not turn. If faulty relay in the mounting block, there may be no clicks at all, or they will be barely audible from the cabin. Also, a relay malfunction is indicated by a lack of voltage at contact 50 solenoid relay when the ignition is turned on.

On Almera Classic starter relay is standard 4 pin relay type 12V 30A, the same is used in cooling fan or fuel pump circuits. It can be temporarily replaced with a known good one from another component (for example, a fan relay) for diagnostic purposes.

Where is the starter relay located on Nissan Almera Classic (photo and diagram)

The location of the relay depends on the year of manufacture and modification of the vehicle. On most Almera Classic (including restyled versions) the starter relay is installed in fuse and relay mounting block, which is located in the cabin under the instrument panel on the driver's side.

To get to the block:

  1. Open the driver's door and sit in the seat.
  2. Lower the steering column to the lowest position for convenience.
  3. Under the instrument panel to the left of the steering wheel, find the plastic cover of the mounting block (it is secured with two latches).
  4. Carefully pry the cover with a screwdriver or flat object and remove it.

Inside the block you will see several rows of fuses and relays. The starter relay is usually located:

  • 📍 On Almera Classic B10 (until 2006) - in top row, third relay from the right (marking may be missing).
  • 📍 On Almera Classic N16 (after 2006) - in bottom row, second relay from the left (next to the fuel pump relay).

For accurate identification, refer to wire color, going to contact 85 relay: it should be red and black with white stripe (typical for the starter circuit on Nissan). You can also temporarily remove the relay and check the inscription on the case - it is often indicated there STARTER RELAY or MAIN RELAY.

📊 What year is your Almera Classic?
  • Until 2003
  • 2003-2006
  • 2006-2012
  • I don't know
Model Year of manufacture Relay location Wire color (pin 85)
Almera Classic B10 1999–2006 Top row, 3rd from right Red-black with white stripe
Almera Classic N16 2006–2012 Bottom row, 2nd from left Red-black with white stripe
Almera Classic (restyling) 2008–2012 Bottom row, 1st from right Red-orange

If your mounting block does not have a relay with this marking, check additional relay block under the hood (next to the battery). On some modifications, the starter relay is located there - it will be in a black plastic case with the inscription 12V 30A.

What to do if the relay is missing from the block?

On some versions Almera Classic (especially early ones) the starter relay can be combined with the ignition relay or absent altogether - its functions are performed by a transistor unit in the ECU. In this case, if you have problems starting, check the circuit from the ignition switch to the starter with a multimeter, as well as the condition of the contacts in the ECU connector (pin 15).

Signs of a bad starter relay

The starter relay fails gradually, and its malfunction can be recognized by several symptoms. Here are the most common signs:

  • 🔋 The starter does not respond to turning the key (no clicks or rotation).
  • 🔊 Repeated clicks of the relay are heard, but the starter does not turn.
  • 🔥 The relay clicks, but no voltage is supplied to the starter (checked with a multimeter).
  • 🔄 The starter works every other time - sometimes it works, sometimes it doesn’t.
  • 💡 When you turn the key, the instruments on the panel go out (indicates a short circuit in the relay).

It is important to distinguish a relay malfunction from problems with battery, starter or ignition switch. For example, if when you turn the key the light on the dashboard dims, but the starter still turns, the problem is most likely in the battery. If there are no clicks at all, and the devices do not go out, the relay or an open circuit is to blame.

⚠️ Attention: If the starter relay is “stuck” in the closed state (the starter turns constantly, even after the key is released), immediately disconnect the battery! This may cause the wiring to catch fire.

For an accurate diagnosis, check the relay with a multimeter. The verification algorithm is described in the next section.

How to test the starter relay with a multimeter

Testing the relay takes no more than 5 minutes and requires a minimum set of tools: a multimeter (in continuity or resistance measurement mode) and a jumper wire. Follow the step by step instructions:

☑️ Preparing to test the relay

Done: 0 / 4
  1. Continuity of the relay winding:

    Connect the multimeter leads to pins 85 and 86 (control contacts). The resistance of a working winding should be within 50–120 Ohm. If the device shows a break (OL) or short circuit (0 ohm) - the relay is faulty.

  2. Checking the contact group:

    Connect the probes to pins 30 and 87 (power circuit). When turned off, the resistance should be OL (open). Then serve 12V to contacts 85 and 86 (possible from battery via wires). A working relay will close 30 and 87 - resistance will become 0 ohm.

  3. Trigger check:

    If the relay clicks when voltage is applied to 85 and 86, but contacts 30-87 do not close - the problem is in the contact group. If there is no click, the winding is faulty.

You can also check the relay without removing it from the block:

  1. Turn on the ignition.
  2. Locate the starter relay and touch it with your finger.
  3. Have an assistant turn the key to the "Start" position. A working relay will be easy to vibrate and make a distinct click.
💡

If you don't have a multimeter handy, temporarily replace the starter relay with a known good one (such as a cooling fan relay). If the starter works, the problem is in the relay.

How to replace the starter relay: step-by-step instructions

Replacing the starter relay with Nissan Almera Classic - a simple procedure that does not require special skills. You will need:

  • 🔧 New relay (analogous to the original one - Nissan 25230-3M000 or Bosch 0 332 014 150).
  • 🔨 Flat screwdriver (for removing the unit cover).
  • 📸 Phone (to photograph the location of the relay before removing it).

Sequence of actions:

  1. Disconnect the battery:

    Remove the negative terminal from the battery to avoid short circuit.

  2. Remove the mounting block cover:

    Carefully pry the latches with a screwdriver and remove the cover. Be careful - plastic is fragile!

  3. Remove the old relay:

    Press the relay lock (usually white) and pull it up. Do not use excessive force; the contacts may bend.

  4. Install a new relay:

    Insert the new relay into the same socket, making sure the pins line up. Press until the latch clicks.

  5. Check the work:

    Connect the battery and try to start the car. If the starter fires clearly, the replacement was successful.

⚠️ Attention: If after replacing the relay the starter still does not work, check fuse F10 (10A) in the mounting block - it is responsible for the relay control circuit. Also inspect ignition switch contact group (often oxidized pin 50).

Cost of a new starter relay for Almera Classic - from 300 to 800 rubles (depending on the manufacturer). Original relay Nissan lasts longer, but analogues from Bosch or Hella also show good results.

Frequent mistakes when diagnosing and replacing relays

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

  • 🔍 The starter relay is confused with the ignition relay:

    On Almera Classic These relays are similar in appearance, but perform different functions. The ignition relay is usually located nearby, but is marked IGNITION RELAY.

  • ⚡ Do not check the fuse:

    If the relay does not click, first make sure the fuse is F10 (10A) intact Its burnout is a common cause of starter silence.

  • 🔧 Using an incompatible relay:

    Relays from other models (for example, from Nissan Primera) may not be suitable for current characteristics. Only use relays on 30A.

  • 📉 Ignore contact oxidation:

    Even a new relay will not work if the contacts in the block are oxidized. Clean them up alcohol solution or special contact liquid.

Another common mistake is checking the relay without taking into account its “polarity”. Contacts 85 and 86 You can mix them up, but if you connect them incorrectly, the relay will not work. B Almera Classic contact 85 usually connected to mass (black wire) and 86 - to plus from the ignition switch (red-black wire).

💡

If after replacing the relay the starter turns, but the engine does not start, the problem may be alarm (blocks the starter circuit) or immobilizer. Check if the immo light on the instrument panel is flashing.

Alternative ways to start the engine with a faulty relay

If the starter relay fails on the road and there is no replacement at hand, you can temporarily start the engine using one of the alternative methods. Important: these methods are only suitable for emergency cases!

  • 🔌 Close the relay contacts manually:

    Remove the mounting block cover, locate the starter relay and remove it. Insert a screwdriver or wire into the connector between pins 30 and 87 (they are responsible for the power circuit). This will directly supply current to the starter. Caution: Sparks are possible!

  • 🔋 Apply voltage to the solenoid relay:

    Open the hood, find the starter and close two large terminals on the solenoid relay with a screwdriver. The engine will start, but this method is dangerous - you can burn the starter winding.

  • 🚗 Push launch:

    Suitable for vehicles with manual transmission. Turn on 2nd gear, depress the clutch and accelerate the car to 10–15 km/h, then quickly release the clutch.

⚠️ Attention: Shorting the starter contacts with a screwdriver can lead to wiring fire, if you short-circuit the wrong terminals. Use this method only as a last resort and make sure there are no flammable materials nearby.

After an emergency start, be sure to replace the starter relay and check the circuit for short circuits. If the relay burns out repeatedly, look for the cause in wiring or starter (it may be drawing too much current due to wear on the brushes).

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

Is it possible to drive without a starter relay if you start the car using other methods?

Technically yes, but it is extremely unsafe. The relay protects the starter circuit from overloads, and its absence can lead to wiring fire or starter failure. Use alternative starting methods only to get to the service station.

Why does the new starter relay burn out quickly?

If the relay burns out repeatedly, the reasons may be as follows:

  • Short circuit in wiring between the relay and the starter.
  • Malfunction solenoid relay (consumes too much current).
  • Problems with ignition switch (contact 50 sticks).
  • Poor quality relay (use only the original or proven analogues).

Check the circuit with a multimeter in continuity mode.

How to distinguish a relay malfunction from a starter malfunction?

Simple test:

  1. Turn the key to the "Start" position. If you can hear clicks, but the starter does not turn - the problem is in the solenoid relay or the starter itself.
  2. If there are no clicks, but the instrument panel does not go out, it is faulty relay in the mounting block.
  3. If the instruments go out, but the starter does not work, it is discharged battery or poor contact at the terminals.

Which starter relay is suitable for Almera Classic N16 2008?

For Almera Classic N16 The following relays are suitable for 2006–2012:

  • Original: Nissan 25230-3M000 or 25230-4M000.
  • Analogues: Bosch 0 332 014 150, Hella 4RA 003 537-331.

The main thing is that the relay is on 30A and had 4 contacts (type 12V SPDT).

Can the starter relay be repaired or just replaced?

The starter relay is a non-repairable part. Its body is sealed, and attempts to disassemble it will damage the contacts. The only option for “repair” is cleaning oxidized contacts in the fuse box connector (sometimes this temporarily restores operation). In other cases, only replacement.
