Genuine Products Alternator 12V 130A Mitsubishi 1800A546

This Genuine Products alternator is a 12V, 130A unit for Mitsubishi applications and is identified by part number 1800A546. It is a new alternator, supplied each, with an internal regulator and a 6 groove pulley, so the electrical and mounting details need to match the vehicle before purchase.

The mounting dimensions provided are important for checking physical fitment: twin leg alternator mount, 54mm inside mounting legs, 185mm mount centre to centre, and 10mm pivot and adjusting holes. Those measurements, along with the pulley outside diameter of 55mm, are the practical points to confirm when comparing against the existing unit.

Genuine Products is listed as the brand, and the alternator is described as an OE-style unit for Mitsubishi use. It carries a 12 month warranty and a weight of 5.96kg, which can help when comparing like-for-like against the part already fitted to the vehicle.

Application and Buying Notes

Before ordering, compare the vehicle’s existing alternator against the key identifiers here: part number 1800A546, 12V system voltage, 130A output, internal regulator, and 6 groove pulley. A match on one detail alone is not enough; the mounting layout and pulley arrangement must also line up for the part to suit correctly.

The physical mounting dimensions are specific to this unit. Check the twin leg mount, 54mm inside mounting legs, 185mm centre-to-centre measurement, and 10mm pivot and adjusting holes against the alternator currently fitted to the vehicle. These are the measurements that usually decide whether the unit will bolt up correctly.

The pulley outside diameter is 55mm, so the belt drive setup should be compared carefully with the existing alternator before fitting. Where belt alignment or pulley section differs, the alternator may not be suitable even if the electrical rating looks similar.

Because this alternator is listed for Mitsubishi applications, the safest buying approach is to verify the vehicle details and the original part number together. If the old unit is still available, matching it against 1800A546 and the listed dimensions is the most practical way to reduce the risk of ordering the wrong part.

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 1800A546 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.
