According to the seller’s compatibility listing, the 11256N is intended for selected Nissan, Infiniti and Suzuki models equipped with the specified engines.

Nissan 11256N Alternator Fitment Chart

Infiniti and Suzuki 11256N Alternator Fitment

Fitment warning: These are seller-advertised application ranges, not independently verified compatibility for every trim and production configuration. Always confirm the original alternator number, electrical connector, mounting points, pulley and VIN.

Nissan Frontier 4.0L V6 Alternator Replacement

The Nissan Frontier is one of the most important applications in this listing.

POBWAV advertises compatibility with 2008–2019 Frontier models equipped with the 4.0L V6.

The Frontier’s VQ40DE V6 is widely used in Nissan’s truck lineup, but that shared engine architecture does not guarantee identical alternators across all model years.

Before ordering the 11256N, verify the original part number and electrical configuration.

Nissan Titan 5.6L V8 Alternator Replacement

The seller lists 2008–2015 Nissan Titan 5.6L V8 applications.

The Titan’s VK56DE V8 supports a full-size pickup with substantial electrical demands, including cooling fans, lighting, cabin accessories and trailer-related equipment.

If the factory alternator has failed, a correctly matched replacement can restore charging performance.

However, don’t assume that every Titan alternator is interchangeable merely because the engine displacement is the same.

Nissan Armada Alternator Replacement

The 2007–2015 Nissan Armada 5.6L V8 is included in the advertised fitment range.

The Armada’s electrical systems can place considerable demand on the alternator, particularly when climate control, lighting, entertainment systems and other accessories operate simultaneously.

Matching the original alternator’s output and connector configuration remains essential.

Nissan Xterra Alternator Replacement

The seller advertises compatibility with 2007–2015 Nissan Xterra 4.0L V6 models.

Before replacing the alternator, inspect the serpentine belt, tensioner and electrical connections.

A charging problem caused by a damaged cable or slipping belt won’t be corrected by installing another alternator.

Nissan NV1500, NV2500 and NV3500 Alternator Replacement

POBWAV also lists several Nissan NV commercial van applications.

Commercial vehicles can spend extended periods operating with electrical accessories and heavy workloads.

That makes correct alternator output particularly important.

The seller’s listing covers selected NV models equipped with the 4.0L V6 and 5.6L V8, with application years varying by model and engine.

Verify the exact configuration before purchasing.

POBWAV 11256N OEM and Interchange Part Numbers

The seller lists the following replacement and interchange references.

These numbers are taken from the seller’s advertised interchange list. They should not be treated as proof that every listed reference is mechanically and electrically interchangeable in every vehicle.

If the original alternator carries a Nissan number such as 23100-ZH00A, compare it with the seller’s confirmed application information before ordering.

How Much Power Does a 130-Amp Alternator Produce?

The POBWAV 11256N is advertised as a 130-amp alternator.

At a nominal charging voltage of 14 volts:

130 amps × 14 volts = 1,820 watts

That’s approximately 1.82 kilowatts of theoretical electrical output at rated current.

However, this doesn’t mean the alternator continuously produces 1,820 watts at idle.

Actual output depends on engine speed, alternator speed, electrical load, temperature and charging-system controls.

The alternator must supply vehicle electrical loads while also restoring energy to the battery.

If you’re running aftermarket lighting, an upgraded audio system, or other high-demand equipment, evaluate the complete electrical system rather than assuming that a 130-amp alternator automatically provides enough reserve capacity.

Seven Signs Your Nissan Alternator Is Failing

1. Battery Warning Light Appears

The battery warning light is one of the most recognizable charging-system symptoms.

Despite the name, it doesn’t necessarily mean the battery itself has failed.

A defective alternator, loose belt, damaged charging cable or faulty electrical connection can trigger the warning.

For a complete breakdown, read our battery warning light troubleshooting guide.

2. Your Battery Keeps Dying

If your Frontier, Titan or Armada repeatedly needs a jump-start, the alternator may not be replenishing the battery.

However, a weak battery or parasitic electrical draw can produce similar symptoms.

Test the battery and charging system before replacing parts.

3. Headlights Dim or Flicker

A charging-system problem can cause noticeable changes in lighting brightness.

These symptoms may become more obvious when the blower motor, rear defroster or other electrical accessories are operating.

4. Whining or Grinding Noise

Worn alternator bearings may produce whining, grinding or rattling sounds.

But don’t overlook the accessory-drive belt, tensioner or idler pulleys.

5. Electrical Accessories Behave Strangely

Low system voltage can contribute to intermittent electronic malfunctions, warning messages and slow accessories.

These symptoms are not exclusive to alternator failure.

6. Burning Smell

Overheated electrical connections, a damaged alternator or a slipping belt can produce a burning odor.

If you notice smoke or melting insulation, stop operating the vehicle safely.

7. Engine Stalls or Won’t Restart

When the alternator stops charging, the battery temporarily supplies electrical power.

Eventually, the battery may discharge enough to interfere with engine operation or prevent restarting.

How to Test a Nissan Alternator Before Replacing It

Replacing an alternator without testing the charging system can turn a simple electrical repair into an expensive guessing game.

A digital multimeter is a useful starting point.

Step 1: Measure Battery Voltage

With the engine off and the battery rested, a fully charged conventional 12-volt lead-acid battery typically measures approximately 12.6 volts.

A significantly lower reading may indicate a discharged battery.

Step 2: Start the Engine

Measure voltage across the battery terminals while the engine is running.

Many conventional charging systems operate around 13.5–14.8 volts during active charging.

However, Nissan charging-control systems can vary output based on operating conditions.

Compare your measurements with the correct factory specifications.

Step 3: Apply Electrical Load

Turn on the headlights, cabin blower and rear-window defroster.

Observe charging-system behavior under load.

Step 4: Inspect the Serpentine Belt

Check for cracking, glazing, contamination and poor tension.

A slipping belt can prevent a functioning alternator from generating adequate power.

Step 5: Check the Charging Cables

A damaged alternator output cable or poor ground can prevent charging current from reaching the battery efficiently.

Our automotive voltage-drop testing guide explains how to locate excessive resistance in electrical circuits under load.

If a wire shows normal voltage but cannot support electrical demand, our automotive wiring load-test guide covers that diagnostic problem in greater detail.

Never disconnect the battery while the engine is running to test alternator operation. This outdated method can produce voltage spikes and damage sensitive electronics.

Five Mistakes to Avoid When Replacing a Nissan Alternator

1. Buying Based on Engine Size Alone

Two Nissan vehicles with a 4.0L V6 or 5.6L V8 may use different alternator configurations.

Verify the original part number.

2. Ignoring Pulley Configuration

The POBWAV 11256N is advertised with a seven-groove pulley.

Confirm that the pulley matches the original belt-drive system.

3. Overlooking the Electrical Connector

An alternator may physically mount to the engine while using an incompatible connector or regulator arrangement.

4. Replacing the Alternator Without Testing the Battery

A weak battery can continue causing starting problems after a new alternator is installed.

5. Ignoring Wiring and Ground Problems

Corroded cables, damaged connections and poor grounds can make a healthy alternator appear defective.
