The situation when you turn the key in the ignition Nissan Almera Classic, you hear a characteristic click, but the engine does not start, familiar to many owners of this model. This does not always mean that the starter has completely failed and requires immediate replacement. Often the problem lies in a simple lack of electricity or poor contact, which can be easily fixed on your own.
Correct diagnosis will save you significant money and time. Unlike modern cars with complex electronics, Nissan Almera Classic has a relatively simple electrical circuit, which allows you to find a fault, armed only with a multimeter and a set of tools. We will look in detail at why the problem occurs and how to fix it.
Initial check of the battery and terminals
The most common reason why the starter clicks but does not turn is a weak charge. battery. When the engine starts, a huge amount of current is required, and if the voltage drops below a critical level, the solenoid relay is activated (making a clicking sound), but the starter winding itself does not receive enough power to rotate the flywheel.
Carefully inspect the terminals on the battery. Oxidation, plaque, or loose wires can block current flow even when the battery is fully charged. Clean the contacts with sandpaper and tighten them tightly. If you are using in winter, make sure that the battery capacity has not dropped due to low temperatures.
Check the voltage at the terminals with the engine off. A normal indicator is considered to be a value from 12.6 up to 12.9 volt. If the multimeter shows less 12.0 B, the battery needs to be charged or replaced. It is also worth checking the condition of the battery case itself for cracks or electrolyte leaks.
Problems with the solenoid relay and contact group
The solenoid relay is a device that both energizes the starter and extends the bendix to engage the flywheel. If the relay clicks, but the contact inside it does not close, the starter will remain motionless. This often occurs due to burnt contacts inside the relay itself.
On Nissan Almera Classic access to the solenoid relay is relatively simple, but requires the removal of some protection elements. If you hear a single click rather than a series of frequent clicks, this may be the problem. Sometimes lightly tapping the relay body helps, which temporarily restores contact, but this is only a temporary measure.
For diagnostics, you can try to apply power directly to the thick bolt of the solenoid relay, connecting it to the battery case with a powerful screwdriver (taking precautions!). If the starter starts to rotate, then the problem is in the control signal or in the relay contact group itself.
⚠️ Attention: When power is applied directly to the solenoid relay, the vehicle may jerk sharply if the vehicle is in gear. Always make sure the car is in neutral or P and the handbrake is applied.
The critical role of mass wires and grounding
Owners often ignore the condition of the ground wire that connects the car body to the engine and battery. If the contact in this place is oxidized or the bolt is loose, the electrical circuit does not close completely. As a result, the starter does not receive a return path for current, and a characteristic clicking sound occurs without rotation.
Locate the thick black wire that runs from the battery to the body or engine. Disconnect it, clean the contact area on the body to a metallic shine and securely fasten it back. This simple action often solves the problem, especially on cars with more than 100 thousand kilometers.
- Single click - no rotation
- A series of clicks - weak battery
- The starter turns, but the engine does not catch
- Another problem
Mechanical faults of the starter itself
If the electrical part has been checked and is working properly, the cause may be hidden inside the starter itself. The most common mechanical failure is wear and tear. bendix (overrunning clutch). The Bendix gear may turn to one side but not engage with the engine flywheel, causing you to hear a hum or click, but the shaft does not rotate.
Another reason may be wear of the armature bushings (bearings). If the bushings are broken, the armature can move and hit the stator, blocking rotation. In this case, the starter often makes not only a clicking sound, but also a metallic grinding or howling sound. The unit must be removed for troubleshooting.
Sometimes the problem is a burnt commutator or worn brushes. The brushes wear out over time and contact with the commutator is lost. In such cases, repairing the starter is often not economically feasible, and it is easier to install a new or reconditioned unit.
- 🔧 Check the condition of the bushings for backlash and scuffing.
- ⚙️ Inspect the bendix for tooth wear and free play.
- 🔋 Make sure that the brushes are not worn down to the minimum length.
- 🔌 Check the integrity of the anchor winding for breaks.
Ignition system and alarm
Sometimes the problem is not with the starter, but with the launch control system. If the immobilizer or alarm system does not recognize the key, it may block the starter from operating. In this case, you may hear the solenoid relay click, but it will not operate completely, or the power simply will not reach the starter.
Pay attention to the key indicator on the dashboard. If it flashes or shows an error, the problem is in the key chip or immobilizer receiving antenna. It is also worth checking the fuse responsible for the starter circuit, although when it blows you usually do not hear a click.
In rare cases, the ignition switch becomes the culprit. The button or mechanical part of the lock may have poor internal contact, interrupting the signal to the solenoid relay. Try moving the key slightly in the lock when trying to start.
☑️ Diagnostics before removing the starter
Step-by-step instructions for replacing the starter
If diagnostics show that the starter is faulty, it will need to be replaced. On Nissan Almera Classic the process is not the easiest due to the cramped engine compartment and the location of the unit near the gearbox. You will need the keys for 10, 12, 14 and 17.
Be sure to remove the negative terminal from the battery first. Next, locate the starter, it is located at the bottom of the engine on the gearbox side. Disconnect the thick power wire and the thin control wire from the solenoid relay. Remove the mounting bolts holding the starter.
Carefully remove the old unit, being careful not to damage adjacent tubes and wires. Install a new starter, tighten the mounting bolts firmly 30-40 Nm. Connect the wires without reversing the polarity. Turn on the ignition and check operation.
If you are not confident in your abilities or you do not have the necessary tools, it is better to entrust this work to professionals. Incorrect installation may result in flywheel damage or short circuit.
| Malfunction | Symptom | Probable Cause | Solution |
|---|---|---|---|
| Single click | The starter doesn't turn over | Poor ground contact or solenoid relay | Cleaning contacts or replacing relays |
| Series of clicks | Quick clicking | Low battery charge | Charging or replacing the battery |
| Howl without rotation | It hums but doesn't turn | Bendix wear | Replacing bendix or starter |
| Grinding | Metal sound | Worn bushings or flywheel | Starter repair or flywheel replacement |
| Silence | No sound | Open circuit, fuse, lock | Checking the electrical circuit |
Is it possible to start the engine with a pushrod?
Yes, if the problem is in the starter and the gearbox is mechanical, you can try to start the engine with a pusher or tow. However, this can be dangerous if the fault is electrical and there is a risk of damaging the gearbox if the gear is not engaged correctly.
Before purchasing a new starter, be sure to remove the old unit and test it on a bench. Often the problem turns out to be small things that can be fixed for pennies, and replacement will not be required.
Prevention and operating tips
To avoid recurrence of the situation, carry out regular preventative measures. Clean the battery terminals from oxides, check the tightness of the contacts and monitor the electrolyte level if you have a serviceable battery. In winter, remove the battery at night in a warm room, if possible.
Do not leave energy consumers (headlights, radio, heating) on for a long time with the engine off. This quickly drains the battery and can lead to sulfation of the plates, after which it will no longer hold a charge even after charging.
If you plan to park the car for a long time, it is recommended to disconnect the negative terminal or use a special ground cut-off device. This will prevent the battery from being slowly drained by leakage currents that can occur due to aging wiring.
Regularly checking the condition of the contacts and battery is 90% of success in preventing engine starting problems on a Nissan Almera Classic.
⚠️ Attention: Never try to start the engine if you hear a loud grinding noise or smoke coming from under the hood. This may result in fire or serious damage to the engine and starter.
When to turn to professionals
Despite the relative simplicity of the design, some faults require specialized equipment. If the problem lies in the engine control unit (ECU) or complex alarm circuitry, DIY repairs may only make the situation worse.
Contact the service if after all the electrical circuit checks the problem persists, or if you are not confident in your skills. Modern diagnostic scanners can read errors that cannot be seen visually and pinpoint the faulty part.
You also need professional help if, when you try to start, you hear unusual sounds coming not from the starter, but from the engine itself. This may indicate serious mechanical problems within the motor that require immediate attention.
How much does it cost to repair a starter?
The cost of repair depends on the type of fault. Replacing the bendix or brushes will cost 1,500-3,000 rubles, a complete overhaul will cost up to 5,000 rubles. A new starter for Almera Classic costs from 8,000 rubles and more.
Why does the starter click but not turn the engine?
The main reason is insufficient current to rotate the armature. This may be caused by a discharged battery, poor contact at the terminals, oxidation of the ground wires, or a malfunction of the solenoid relay.
Is it possible to drive if the starter sometimes clicks?
No, this is an unreliable state. At any moment, the starter may stop starting the engine completely, leaving you stranded on the road. In addition, constant attempts to start can completely kill the battery or burn out the solenoid relay.
How to check the starter without removing it?
You can check the voltage at the starter terminals when trying to start. If the voltage drops to zero, the problem is in the power circuit or battery. If there is voltage, but the starter does not turn, the problem is in the unit itself.
What to do if the starter clicks when cold?
When the engine is cold, the oil thickens and the starter needs more power. If the battery is old or the contacts are oxidized, it may not cope. Check the battery charge and the condition of the contacts, especially in winter.
Timely diagnosis and elimination of minor faults prevents costly repairs to the starter and engine in the future.
⚠️ Attention: Never short-circuit the starter terminals with a screwdriver without hand and eye protection, as this may cause sparks, burns, or the battery may explode if vapors are present.
