Mitsubishi Alternator 12V 105A - Part No. 1800A388

This Mitsubishi alternator is a 12V, 105A unit with internal regulation, twin leg mount and IR70 pin code. It is listed as a new alternator and carries part number 1800A388, which is the most useful reference when checking replacement suitability against the vehicle or the original unit.

As an OE product in the rotating electrical range, it is intended for buyers who need a direct alternator replacement with the correct electrical rating and mounting style. The unit is supplied each, so the key checks are voltage, amperage, regulator type, mount style and part number before ordering.

The stated warranty is 2 years or 400,000km. That gives a clear service-life reference, but it does not replace the need to match the alternator to the application details, especially where the mount type, pin code or charging specification may vary between vehicles.

Application and Buying Notes

For alternators, the safest check is to match the part number 1800A388 first, then confirm the electrical and mounting details. This unit is 12V with a 105A output, internal regulator and twin leg mount, so those specifications need to line up with the vehicle's charging system and the original alternator configuration.

The pin code is IR70, which is another important compatibility checkpoint when comparing connectors and alternator variants. Even where the vehicle is in the Mitsubishi ASX range, the correct match still depends on the exact application and the alternator fitted to the vehicle originally.

A new alternator is generally chosen when the aim is to replace a worn or failed unit with the same style and rating. The listed warranty of 2 years or 400,000km gives added context, but it remains important to verify the mounting ears, connector arrangement and output rating before purchase.

If you are comparing against an existing alternator, the most reliable details to check are the stamped or tagged part number, the 12V system voltage, the 105A amperage rating and the twin leg mount. Those four points, together with the IR70 pin code, are the practical indicators that help avoid ordering the wrong unit.

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 1800A388 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.
