Mechman Alternator Warranty & Service Program Explained

A high output alternator is a real investment, so it is reasonable to ask what stands behind it. This guide explains how Mechman supports its alternators through its manufacturer’s warranty, available extended coverage and out-of-warranty rebuild service.

Important: Warranty coverage can vary by product and may change over time. Always confirm the current terms for your specific alternator at the time of purchase. This article is a general overview and is not the official warranty document.

The standard Mechman alternator warranty

Mechman alternators include a manufacturer’s limited warranty covering eligible repairs for a defined period following the original purchase date.

In general, the limited warranty:

• Covers the alternator itself during the applicable warranty period
• Does not cover installation or removal labor
• Does not cover damage to batteries, wiring or other vehicle components
• Requires proof of purchase, so you should retain your original invoice
• Applies to the original purchaser and is generally non-transferable
• Requires the alternator to be installed and used in its intended application

The exact coverage period and conditions can depend on the alternator purchased. Check the applicable product information and current warranty terms before ordering.

Extended warranty options

Extended warranty options may be available on qualifying Mechman alternators. Depending on the product, these options may include one-year, two-year or lifetime coverage tiers.

Extended coverage is not necessarily offered for every alternator or application. Confirm the available options, coverage period and included services when purchasing your unit.

Out-of-warranty flat-rate rebuild service

Warranty coverage and out-of-warranty rebuild service are separate programs.

Mechman currently offers an in-house flat-rate rebuild service for customers who want their original Mechman alternator restored using new internal components. The currently published flat-rate price is $249.

The published rebuild service includes:

• Replacement of internal components such as bearings, brushes, rectifier and regulator
• Pulley replacement when necessary
• Retention of the alternator’s original housing
• A 60-day limited warranty on the replaced internal components

Cosmetic work and refinishing of the original housing are not included.

Because pricing and program details can change, confirm the current rebuild price and requirements with Mechman before shipping an alternator for service.

What can void a warranty?

Warranty coverage may be denied when an alternator has been modified, improperly installed, physically damaged, misused or operated outside its intended application.

Common problems that can affect coverage include:

• Installing the alternator on an application for which it was not designed
• Using incorrect wiring or undersized charging cables
• Improper grounding
• Using an incorrect belt or pulley arrangement
• Modifying or disassembling the alternator
• Operating it beyond the stated RPM limits
• Physical, environmental or electrical damage unrelated to a manufacturing defect

Order the correct application

Always match the alternator to the exact year, make, model and engine. Factory connectors, computer-controlled charging systems, mounting arrangements and belt configurations can differ even between visually similar vehicles.

If you are unsure about fitment, contact us before ordering.

Install the charging system correctly

A high output alternator can deliver considerably more current than the vehicle’s original unit. Proper charging and ground cables are necessary to carry that additional output safely.

Many installations require a correctly sized Big 3 wiring upgrade along with the appropriate belt and pulley configuration. Proper installation protects the alternator, the vehicle and your warranty coverage.

How a warranty claim generally works

Although the precise process can vary, a typical warranty claim includes the following steps:

1. Locate your original invoice or proof of purchase.
2. Contact AlternatorOutlet.com or Mechman before shipping the alternator.
3. Provide the product information and a description of the problem.
4. Follow the supplied return and shipping instructions.
5. Mechman evaluates the alternator and determines whether the repair qualifies for warranty coverage.
6. The alternator is repaired or serviced according to the applicable terms.

Do not ship an alternator without first confirming the correct procedure and destination.

For an out-of-warranty unit, ask specifically about the current flat-rate rebuild program and any applicable inbound or return shipping costs.

How to protect your coverage

A few simple precautions can help prevent service problems:

• Save your original invoice.
• Confirm exact vehicle and engine fitment before ordering.
• Follow the supplied installation instructions.
• Use properly sized charging and ground cables.
• Install the correct belt and pulley configuration.
• Do not modify or disassemble the alternator.
• Observe the alternator’s operating and RPM limitations.
• Retain records and photographs of the installation.
• Contact us promptly if you experience a charging problem.

Frequently asked questions

How long is a Mechman alternator warranty?

The applicable warranty period can depend on the product and coverage selected at purchase. Extended one-year, two-year and lifetime options may be available on qualifying units. Confirm the exact coverage shown for your alternator before purchasing.

Does the warranty cover installation labor?

Generally, no. The manufacturer’s warranty covers eligible service to the alternator itself. It does not normally cover the labor required to remove or reinstall it or damage to unrelated vehicle components.

What if my Mechman alternator is out of warranty?

Mechman currently publishes a $249 flat-rate rebuild service for original Mechman alternators. The service replaces internal components, retains the original housing and includes a 60-day limited warranty on the rebuilt internal components. Confirm current pricing and eligibility before sending your alternator.

Is the warranty transferable?

The manufacturer’s limited warranty is generally issued to the original purchaser and is not transferable. Confirm the terms associated with your particular purchase.

Will upgrading my wiring void the warranty?

A properly performed wiring upgrade should support reliable alternator operation. Problems arise when wiring is undersized, incorrectly routed, poorly grounded or improperly fused. Follow appropriate installation practices and contact us if you need help selecting charging-system cables.

Do I need authorization before sending an alternator back?

Yes. Contact AlternatorOutlet.com or Mechman before shipping a unit. This ensures that you receive the correct instructions and that your alternator is directed to the appropriate warranty or rebuild-service process.

The bottom line

Mechman supports its alternators through manufacturer warranty coverage, extended options on qualifying products and a paid flat-rate rebuild program for out-of-warranty units.

Save your invoice, order the correct alternator for your application and install it with the proper wiring and belt system. If a problem occurs, contact us before removing or shipping the alternator so we can help determine the appropriate next step.
