Application and Buying Notes

To confirm the right match, compare the alternator on the vehicle with the listed identifiers: ERR6999 is supplied as both the part number and OEM number, and the electrical rating is 12V 120A. Those details should align before the unit is fitted, especially on Land Rover Defender applications where different charging system versions may exist.

If you are replacing a failed alternator, check the original label, connector arrangement, mounting points, and output rating before ordering. This listing does not provide connector, pulley, or mounting details, so the safest buying decision is to match ERR6999 against the existing part and the vehicle application.

The unit is described as new rather than remanufactured, which may matter if you are comparing replacement options. Warranty is unknown, so it is sensible to confirm the return and warranty arrangements with Micks Gone Bush before installation if that is important to your purchase.

Because the fitment preview only confirms Land Rover Defender coverage in the supplied application data, do not assume broader Land Rover compatibility without checking. A correct alternator match depends on the exact vehicle setup, and the part number is the most reliable starting point for verification.

Before supply, the safest approach is to confirm the original unit details against the listed part number, voltage, output rating, mounting arrangement, and pulley configuration. That checking process is standard practice in the parts trade because visually similar units can still differ in service-critical ways.

For workshop, fleet, and equipment applications, accurate identification of part number ERR6999 helps avoid unnecessary freight, additional labour, and vehicle or machine downtime. Where the application is not straightforward, the original unit, OEM reference, or workshop records should be used as the primary confirmation point.
