In this article we will analyze all current generator articles for Lancer 9 1.6 (including original and proven analogues), we will learn to distinguish fakes from quality parts, and also give step-by-step instructions for replacement, taking into account typical mistakes. We will pay special attention hidden pitfalls when buying used generators and connection nuances on models with air conditioning.

Original generator articles for Lancer 9 1.6 (4G18)

Factory generator for Mitsubishi Lancer IX with motor 1.6 l (4G18) has several variations depending on the year of manufacture and configuration. Main original items:

• 🔧 MR543944 — basic version without air conditioning (until 2005). Power 70 A, 2 bolt mounting.
• ❄️ MR543945 — for cars with air conditioning (high load). Power 80 A, differs in pulley and connection diagram.
• 🔄 MR583109 — restyled version (2005–2008), compatible with both types of kits.

Important: article numbers may be duplicated for other models Mitsubishi (for example, Colt or Carisma), but the mounts and connectors are sometimes different. Check before purchasing Vehicle VIN code or check the catalogs Mitsubishi Parts.

On the secondary market you can often find generators with article numbers MR543946 or MR583110 - these are not originals, but replicas from third parties (for example, Denso or Hitachi for the Asian market). They can be installed, but only after checking compatibility with:

• 🔌 Type of connector (round or rectangular).
• 🔧 Pulley diameter (must match the belt 6PK1715).
• ⚡ Voltage regulator (for Lancer 9 - strictly 14.2–14.5 V).

Generator analogues: which brands to choose?

Original generators Mitsubishi cost from 15,000 to 25,000 rubles, so many owners choose analogues. The best proven brands:

Brand	Article	Power (A)	Compatibility	Price (₽)
Denso	DGR0104	80	With air conditioning	12 000–14 000
Hitachi	LRA01043	70	Without air conditioning	9 500–11 000
Bosch	0 986 041 920	75	Universal	10 500–13 000
Valeo	583110	80	With air conditioning (restyle)	11 000–12 500

⚠️ Attention: Cheap analogues (for example, Fenox or Starline) often have weak bearings and voltage regulators. Their resource rarely exceeds 50,000 km. If the budget is limited, it is better to take a used original from disassembly (tested at the stand) or Denso/Hitachi with a guarantee.

When choosing an analogue, be sure to check:

1. Type of fastening (the length of the “ears” may differ by 2–3 mm).
2. Polarity (per Lancer 9 — "minus" on the body).
3. Availability of an additional connector for a tachometer (not available on all analogues).

Signs of a generator malfunction: when is it time to change it?

Generator on Lancer 9 1.6 It rarely fails suddenly - there are usually warning signs. Main symptoms:

• 🔋 Battery light is on on the instrument panel (even after replacing the battery).
• 💡 Dim headlights and interior lighting when the engine is running.
• 🔊 Extraneous sounds (howling, creaking) from the generator are a sign of bearing wear.
• 📉 Voltage drop is lower 13.8 V at idle (checked with a multimeter).
• 🚗 Jerks when driving - may indicate a voltage drop in the on-board network.

⚠️ Attention: If, after starting the engine, the voltage at the battery terminals exceeds 14.8 V, this is a sign of a malfunction voltage regulator (Often this can be replaced separately without purchasing the entire generator).

For diagnostics:

1. Measure the voltage at the battery with the engine off (should be 12.6–12.8 V).
2. Start the car and check the voltage at idle (normal: 13.8–14.5 V).
3. Turn on the headlights, heater and heated glass - the voltage should not drop below 13.5 V.

How to check the diode bridge without removing the generator?

Remove the “+” terminal from the battery and connect a multimeter in diode test mode between terminal “30” (thick wire) of the generator and ground. The resistance should be infinite in one direction and ~500–700 Ohms in the other. If the readings are the same in both directions, the bridge is broken.

Step-by-step instructions for replacing the generator on Lancer 9 1.6

Replacing the generator with Mitsubishi Lancer IX does not require a special tool, but there are some nuances. You will need:

• 🔧 10, 12 and 14 mm wrenches (heads with an extension are better).
• 🔨 A pry bar or lever to move the generator.
• 🔌 Screwdriver for removing protection (if available).
• 📏 Rubber gasket for a new generator (often not included).

⚠️ Attention: Before starting work disconnect the negative terminal of the battery! On some versions Lancer 9 the generator is connected to the on-board network even when the ignition is turned off.

Disconnect the negative terminal of the battery|Remove the alternator belt (loosen the tensioner)|Disconnect the connector and power wire|Unscrew the alternator mountings (2 bolts)|Check the new alternator for compatibility-->

Step 1: Removing the belt.

Loosen the tension roller nut with a wrench 12 mm and move the roller with a pry bar to loosen the belt. Remove the belt from the pulleys.

Step 2: Disconnect wiring.

Disconnect tachometer connector (small round connector) and unscrew the nut securing the power wire (the key is on 10 mm). Remember the location of the wires - on some analogues the connectors may be mirrored!

Step 3. Dismantling the generator.

Unscrew the two mounting bolts (upper and lower) and carefully remove the generator. Please note gasket between generator and bracket - It is advisable to replace it.

Step 4: Install a new generator.

Before installation, check:

• 🔄 Coincidence of pulleys (diameter and number of streams).
• 🔌 Position of connectors (must match without tension).
• ⚡ Output voltage (check with a multimeter while rotating the pulley).

Install the generator in the reverse order, tension the belt (the deflection should be 8–10 mm when pressed with a finger) and connect the battery.

Typical replacement mistakes and how to avoid them

Even experienced car owners make mistakes when replacing an alternator with Lancer 9. Let's look at the most common ones:

1. Reversed polarity.
   

   On some analogues (for example, Bosch) the “+” terminal may not be at the back, but at the top. If you do not notice this during installation, the diode bridge will burn out.

2. Incorrect belt tension.
   

   A weak belt will slip and will not provide the required tension, and an overtightened belt will accelerate wear on the generator and pump bearings.

3. Ignoring the gasket.
   

   Without a gasket, the generator will vibrate, which will lead to destruction of the fasteners or broken wiring.

4. Purchasing a generator without taking into account the air conditioner.
   

   Generator from the version without air conditioning (70 A) will not support the compressor load, which will lead to constant undercharging of the battery.

⚠️ Attention: If after replacing the generator the lamp on the panel lights up CHECK ENGINE, check the connection of the tachometer connector. On Lancer 9 it is connected to the ECU, and its break can cause an error P0562 (low voltage on-board network).

Generator repair: what can be repaired?

It is not always necessary to replace the entire generator; often it is enough to replace individual components. What needs to be repaired:

• 🔄 Voltage regulator (cost 800–1,500 rubles). Signs of malfunction: voltage surges or lack of voltage.
• ⚙️ Bearings (front and rear, price 300–600 ₽ per piece). Symptoms: howling or play of the pulley.
• ⚡ Diode bridge (1,200–2,000 RUR). Broken diodes lead to undercharging of the battery.
• 🔌 Brushes (200–400 ₽). Brush wear manifests itself as a gradual drop in charge.

Repair is justified if:

• The generator housing is not damaged.
• The stator and rotor windings have no breaks (checked with a multimeter).
• The cost of repairs does not exceed 50% of the price of a new generator.

💡 Advice: If you decide to repair the generator yourself, use repair kits from Denso or Hitachi - These include bearings, brushes and regulator. Cheap Chinese kits often contain defective parts.

How to check the generator windings?

The resistance of the field winding (rotor) should be in the range of 2.3–2.7 Ohms. The stator windings are checked for open circuit (resistance between terminals ~0.2 Ohm) and for breakdown to the housing (should be infinite).

FAQ: Frequently asked questions about Lancer 9 1.6 generators

Is it possible to install a generator from Lancer 10 on Lancer 9 1.6?

No, generators Lancer X (including versions with motor 1.6) are not compatible with Lancer IX due to different mountings, pulleys and electrical connectors. Exception - some models Lancer X with engine 1.5 l, but their power (90 A) is excessive for Lancer 9.

Which generator is better - original or Denso?

Denso often supplies generators to the assembly line Mitsubishi, so they are not inferior in quality to the original, but are cheaper. The main thing is to buy from official distributors, as there are many fakes on the market. The original is justified if you need 100% compatibility without modifications.

How long does the generator last on Lancer 9 1.6?

Service life of the original generator - 150,000–200,000 km. Analogs last less: Denso/Hitachi — 100,000–150,000 km, budget brands — 50,000–80,000 km. The service life depends on operating conditions (frequent short trips, humidity, belt quality).

Why does the battery drain quickly after replacing the generator?

Probable reasons:

1. The new generator is faulty (check the voltage at idle).
2. Poor contact of the power wire or tachometer connector.
3. Weak belt tension (slips).
4. The battery is faulty (does not hold a charge).

First, measure the voltage at the battery with the engine running. If it is lower 13.8 V - the problem is in the generator.

Is it possible to drive with a faulty generator?

For a short time (before the workshop) - yes, but only if the battery is fully charged. Driving for a long time on battery power will lead to:

• Deep discharge of the battery (after which it may not recover).
• Electronics failure (ECU, alarm, radio).
• Problems starting the engine.

If the generator does not charge, it is better to call a tow truck or have the car towed.
