Nissan Almera Classic (especially models B10 And N16 with gasoline engines GA14DE, GA16DE, QG15DE) is famous for its reliability, but over time even it has problems starting the engine. One of the most common malfunctions is failure starter relay. Symptoms can range from a clicking sound when turning the key to no response at all when starting. In this article, we will look at how to independently diagnose the problem, check the relay with a multimeter, and, if necessary, replace or repair it without contacting service.

It is important to understand that the solenoid relay (aka traction relay or starter solenoid) performs two key functions: retraction bendix for engagement with the flywheel and short circuit contacts for supplying current to the starter winding. If the relay fails, the engine will either not start at all or will start on the third to fifth attempt. In this case, the problem may be disguised as a discharged battery or a faulty starter - so the diagnosis must be accurate.

Signs of a malfunctioning retractor relay on Nissan Almera Classic

The first signal about problems with the solenoid relay is unstable engine start. Here are typical symptoms that should alert you:

  • 🔊 Starter clicking without cranking — when you turn the key, a single loud click is heard, but the starter does not rotate. This is a sign that the relay is triggered, but the contacts do not close.
  • 🔄 Multiple clicks — a series of quick clicks when holding the key in the “start” position. Often indicates burnt contacts inside the relay.
  • ⚡ The starter turns idle — the sound of the starter rotating is heard, but the engine does not start (the Bendix does not engage the flywheel).
  • 🔋 Launch "every other time" — the car starts only after several attempts, especially in cold weather.
  • 💥 Burning smell from under the hood — with frequent repetition of startup attempts, a smell of burnt insulation may appear.

If you observe at least one of these signs, do not rush to replace the entire starter. In 70% of cases, the solenoid relay is to blame, which can be replaced separately (or repaired). For example, on Almera Classic N16 with engine QG15DE the original relay costs approx. 1,500–2,500 rubles, while a new starter will cost 8,000–12,000 rubles.

⚠️ Attention: If when you turn the key the starter does not respond at all (there is not even a click), first check fuse F10 (10A) in the fuse box and starter relay (usually located near the fuse box under the hood). On Almera Classic it often burns out due to power surges.

How to check the starter solenoid relay without removing it

Before removing the starter, you can perform preliminary diagnostics right by car. You will need a multimeter (or at least a 12V test light) and a helper (to turn the ignition key).

Step 1: Check the voltage on the control wire

  • 🔧 Disconnect thin wire (usually red or purple) from the solenoid relay.
  • 📊 Connect the multimeter in mode DC 20V between this wire and ground (for example, the starter housing).
  • 🔑 Ask an assistant to turn the key to the “start” position. The voltage should be 12V. If it is not there, the problem is in the control circuit (ignition switch, relay, fuse).

Step 2. Checking the relay operation

  • 🔊 Listen to the sound when you turn the key. If there is a click, but the starter does not turn - burnt contacts inside the relay.
  • 🔋 If there is no click, but there is voltage on the control wire - winding faulty relay

Step 3. Checking "directly" (if you have access to the starter)

  • 🔧 Disconnect thick positive wire from the solenoid relay.
  • 🔋 Short circuit with a screwdriver control contact (thin wire) and positive bolt relay If the starter spins, the relay is faulty.
⚠️ Attention: When checking "directly" Do not touch the starter housing or other metal parts with the screwdriver. - this will cause a short circuit! Also make sure the car is in neutral.

Connection diagram for the solenoid relay Nissan Almera Classic

To properly diagnose the problem, you need to understand how the starter electrical circuit works. Below is a simplified diagram for Almera Classic B10/N16:

Chain element Purpose Typical faults
Battery Power supply (12V) Discharge, terminal oxidation, poor contact
Ignition switch Sends a signal to the starter relay when the key is turned Worn contacts, broken wiring
Starter relay (in fuse box) Controls the supply of current to the solenoid relay Burnout, stuck contacts
Solenoid relay Retracts the bendix and closes the starter circuit Burnt contacts, broken winding
Starter Spins the engine flywheel Wear of brushes, bearings, windings

On Almera Classic the solenoid relay has three contacts:

  1. Manager (thin wire from the starter relay).
  2. Plus (thick wire from the battery).
  3. Starter output (thick wire to the starter winding).

If during testing it turns out that 12V is supplied to the control contact, but the relay does not operate, it must be removed for detailed diagnostics or replacement.

💡

Before removing the starter, be sure to turn off negative battery terminal - this will protect you from a short circuit and reset the ECU settings (if any).

Step-by-step instructions for replacing the solenoid relay with Nissan Almera Classic

If diagnostics confirm a faulty relay, it can be replaced separately from the starter. On Almera Classic it takes about 30–60 minutes if you have a tool. You will need:

  • 🔧 Keys on 10, 12, 14.
  • 🔨 Screwdriver with a flat tip.
  • 🔋 Multimeter (to check the new relay).
  • 🧤 Gloves (the relay is often covered with dirt).

Step 1: Removing the starter

  1. Disable negative battery terminal.
  2. Disconnect positive wire from the solenoid relay (key on 12 or 14).
  3. Unscrew two starter mounting bolts to the gearbox housing (key on 14).
  4. Carefully pull the starter down (you may need to twist it a little from side to side).

Step 2. Disassembling the starter and replacing the relay

  1. Unscrew two bolts, attaching the solenoid relay to the starter housing (usually turnkey on 10).
  2. Remove the relay by pulling it up. Be careful - there may be a spring inside!
  3. Install a new relay (original - Nissan 23300-4M000 or analogues Bosch 0 332 209 155, Valeo 438166).
  4. Tighten the relay mounting bolts firmly 10–12 Nm.

Step 3: Reassembly and Testing

  1. Reinstall the starter and secure with bolts.
  2. Connect the positive wire to the relay.
  3. Connect the negative terminal of the battery.
  4. Try starting the car. If the starter turns briskly, the repair was a success!

Solenoid relay repair: when is this possible?

It is not always necessary to buy a new relay - in some cases it can be repair. This is relevant if:

  • 🔥 Burnt contacts (they can be cleaned with sandpaper).
  • 🧲 Anchor jammed (cleaning and lubrication will help).
  • 🔄 The spring has weakened (can be replaced with a new one).

What you will need for repair:

  • Sandpaper (P1000 for cleaning contacts).
  • Lubrication Litol-24 or WD-40.
  • Soldering iron (if you need to repair burnt wires).
  • Flathead screwdriver for disassembly.

Step by step repair:

  1. Disassemble the relay by carefully removing the cover (it may have rivets or screws).
  2. Clear contact "nickels" sandpaper until shiny.
  3. Check winding multimeter in mode 200 Ohm - there must be resistance 1–3 ohms. If there is a break, the relay must be replaced.
  4. Lubricate moving parts (armature, spring) with a thin layer of lubricant.
  5. Assemble the relay and check its operation on the starter.
⚠️ Attention: If inside the relays are found melted or charred parts, cracks on the body - repair is useless, you need to install a new one. It is also not recommended to repair a relay if it has already been repaired before (the life of the parts is limited).
How to check the relay coil with a multimeter?

Connect the multimeter probes to the winding terminals (usually two small contacts on the relay body). If the device shows infinity (OL) - winding break. If the resistance is close to 0 ohm - short circuit. Normal value for Almera Classic — 1.5–2.5 Ohm.
