<em>Nissan Almera Classic</em>starter relay: signs of malfunction and do-it-yourself replacement

Nissan Almera Classic (also known as Nissan Sunny B10 in some markets) is a reliable sedan, but even it has problems starting the engine over time. One of the common reasons is starter relay - a small but critical element of the electrical system. If you hear clicks when you turn the key, but the starter does not turn, or the engine starts only after several attempts, this may be the culprit.

In this article we will figure out where the starter relay is located on Almera Classic, how to check it with a multimeter, what symptoms indicate a breakdown, and how to replace the part yourself - without contacting service. We will also give original articles and analogs of relays, which are suitable for models 2006–2012 with gasoline engines QG15DE And QG16DE.

Where is the starter relay located on Nissan Almera Classic?

Unlike many modern cars, where the starter relay is integrated into the fuse box, on Almera Classic it is located separately - directly on the starter housing. This makes access easier, but requires the air filter to be removed for easy replacement.

Exact location:

• 🔧 Under the hood, on the driver's side, next to the battery.
• 🔍 The relay is a small black or gray plastic block with two contacts, screwed to the starter with a 10 bolt.
• 📍 On some modifications (for example, with air conditioning), access to the relay may be difficult due to pipes - they will have to be temporarily removed.

In order not to confuse the starter relay with other elements, pay attention to the wires: they fit to it thick red cable (from the battery) and thin control wire (from the ignition switch). If your car has an immobilizer installed, there may be an additional locking relay nearby - you do not need to touch it.

Signs of a bad starter relay

Starter relay on Almera Classic rarely fails suddenly - usually the malfunction appears gradually. Here are the key symptoms to watch out for:

Symptom	Probable Cause	Actions
Clicking sound when turning the key, but the starter does not turn	Burnt relay contacts or broken winding	Ring the relay, replace
Starter works after several attempts	Worn contacts or weak signal from the ignition switch	Check relay and wiring
Constant rotation of the starter after starting the engine	Relay contacts sticking (dangerous for Bendix!)	Urgent relay replacement
No response when turning the key	Open circuit or malfunction of the ignition switch	Ring the circuit from the relay to the lock

⚠️ Attention: If the starter turns, but the engine does not start, the problem is most likely not in the relay, but in the fuel system, spark plugs or crankshaft sensor. Don't confuse the symptoms!

On Almera Classic With a mileage of more than 150 thousand km, a combined malfunction often occurs: both the relay and the Bendix starter. In this case, clicks during startup may be accompanied by a metallic grinding sound - this is a signal for a comprehensive repair.

How to test the starter relay with a multimeter?

Before replacing the relay, you should make sure that it is the problem. For diagnostics, you will need a multimeter (or even a simple 12V test lamp). The test can be performed without removing the relay, but for accuracy it is better to remove it.

Verification algorithm:

1. Remove the relay from the starter (unscrew the 10mm bolt and disconnect the terminals).
2. Switch the multimeter to continuity mode (or resistance measurement).
3. Connect the probes to the relay contacts:
   • 🔌 Pins 85 and 86 (managers): there must be resistance 50–120 Ohm.
   • 🔌 Contacts 30 and 87 (power): in the normal state the circuit is open (resistance → ∞).

Apply 12V to pins 85 and 86 (you can from the battery through a light bulb). In this case, a click should be heard, and contacts 30 and 87 should close (resistance → 0).

If the relay does not click or the contacts do not close, it needs to be replaced. Also inspect the housing for melting or burning - this is a clear sign of a malfunction.

Step-by-step instructions for replacing the starter relay

Replacing the relay with Nissan Almera Classic takes no more than 20 minutes if you follow the instructions. You will need:

• 🔧 Key 10 (for the relay mounting bolt).
• 🔧 Screwdriver with a flat blade (for removing terminals).
• 🔧 New relay (see article numbers below).
• 🔧 Heat shrink tube or electrical tape (to protect contacts).

Procedure:

1. Disable negative battery terminal (required!).
2. Remove the air filter (unscrew the 4 housing mounting bolts).
3. Find the relay on the starter - it is bolted to the housing.
4. Disconnect the terminals (memorize or photograph their location!).
5. Unscrew the mounting bolt and remove the old relay.
6. Install a new relay, connect the terminals in reverse order.
7. Secure the relay with a bolt and put everything back together.

⚠️ Attention: After replacing the relay, check the operation of the starter before assembling the air filter. If the engine does not start or the relay clicks again, the problem may be ignition switch or wiring (especially at the solder joints under the steering wheel).

Articles and analogues of starter relays for Almera Classic

Original starter relay for Nissan Almera Classic (B10) has article number 25070-4M000 or 25070-4M005 (depending on the year of manufacture). However, the original is expensive (from 1,500 rubles), so many owners choose high-quality analogues:

Manufacturer	Article	Price, rub.	Notes
Nissan (original)	25070-4M000	1500–2000	1 year warranty, best quality
Mitsubishi	MR585517	800–1200	Complete analogue, reliable
Bosch	0 332 209 150	600–900	Good price/quality ratio
Febi	25070	500–700	Budget option, average resource

When choosing an analogue, pay attention to switching current - it must be no less 30A. Cheap relays from AliExpress (price ~200 rubles) often cannot withstand the load and burn out after 1–2 months.

How to distinguish a fake relay from the original?

Original relay Nissan has:

1. Clear marking of the article number on the case (laser engraving, not paint).

2. Tight fit of contacts without play.

3. Weight ~50 grams (fakes are lighter due to cheap plastic).

4. Packaging with a hologram and barcode, which can be checked on the manufacturer’s website.

Common mistakes when replacing a starter relay

Even experienced car owners sometimes make mistakes that lead to repeated breakdowns. That's what can't do when replacing the relay with Almera Classic:

• ⚡ Ignore wiring check. If the relay burns out due to a short circuit, the new one will not last long. Be sure to check the wires from the ignition switch to the starter.
• ⚡ Install the relay "by eye". Even if it looks similar, the parameters may not match. For example, a relay from Nissan Primera P12 not suitable for Almera Classic due to different operating currents.
• ⚡ Tighten the fastening bolt firmly. The relay housing is plastic and can be easily broken. The tightening torque should not exceed 1.5 Nm.
• ⚡ Do not clean contacts. Oxidized terminals impair current conductivity and shorten the life of the relay. Sand them with fine sandpaper before installation.

Another typical problem is mixed terminals when connected. If you swap the control and power wires, the relay will burn out immediately upon first startup. To avoid this, before removing the old relay take a photo of the location of the wires or mark them with a marker.

When is it necessary to replace not the relay, but the starter itself?

The starter relay is not the only cause of starting problems. If symptoms persist after replacing it, check:

• 🔋 Battery: voltage must be no lower 12.4V (if less, the starter will not be able to crank the engine).
• 🔧 Starter:
  • Wear bendix (characteristic grinding noise when starting).
  • Burnt brushes (the starter turns slowly or jerkily).
  • Jammed rotor (complete lack of reaction).
• 🔑 Ignition switch: if the contact group is worn out, the signal to the relay may not be received.
• 📶 Immobilizer: on Almera Classic with NATS it can block startup if the key chip fails.

To distinguish between a bad starter and a relay problem, perform a simple test:

1. Turn the key to the ignition position (without starting the engine).
2. Close with a screwdriver pins 30 and 87 to the relay (power and output).
3. If the starter spins, the problem is in the relay or control circuit. If not, the starter itself is to blame.

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

Is it possible to drive with a faulty starter relay?

Technically yes, but it comes with consequences:

• If the relay doesn't work, you will not start the car without a pusher or tow.
• If the relay sticks, the starter will work after the engine starts, which will lead to engine failure.
• In both cases, you risk being left without transport at the most inopportune moment.

How much does it cost to replace a starter relay at a service center?

The cost of work depends on the region:

• Moscow/St. Petersburg: 800–1500 rub.
• Regions: 500–1000 rub.
• Many services charge a minimal fee for diagnostics (300–500 rub.), even if you bring your own relay.

Replacing it yourself will only cost the cost of the part (500–2000 rub.).

Will the starter relay from other Nissan models work?

Yes, but with reservations:

• 🔹 Nissan Sunny B10 (1995–2000) - complete analogue, same article.
• 🔹 Nissan Primera P11/P12 - only relay with article number 25070-4M005 (check the trip current!).
• 🔹 Nissan Almera N16 — does not fit, different mount.
• 🔹 Nissan Micra K12 - can be used as a last resort, but the resource will be lower.

It is better to take a relay with the original article number or proven analogues (Bosch, Mitsubishi).

What should I do if, after replacing the relay, the starter still does not work?

The problem may be something else:

1. Check fuse F10 (10A) in the fuse box - it is responsible for the starter control circuit.
2. Call wire from ignition switch to relay (pin 85). It often rubs around the steering column.
3. Remove the starter and test it on a bench. On Almera Classic often wears out rotor bushing.
4. If the car has an immobilizer, try retraining the key (the procedure is described in the manual).

How to extend the life of the starter relay?

A few simple rules:

• 🔋 Do not keep the key in the "start" position for longer 5 seconds - this reduces the life of the relay.
• 🔧 Regularly clean battery terminals and relay contacts from oxidation.
• 🚗 Avoid short trips in winter - frequent cold starts increase the load on the starter.
• 🔌 If additional equipment is installed (for example, a subwoofer), make sure that it does not create voltage drops during startup.
