OEX Alternator 12V 80A Mitsubishi Style MXA304

The OEX Alternator MXA304 is a new 12V, 80A unit in Mitsubishi style, supplied with a twin leg mount and internal regulator. It is listed with a 4 groove pulley, 60mm pulley outside diameter, 55mm inside mounting legs, and an 8.5mm pivot hole diameter.

This alternator is identified as part number MXA304, with pin code IR49 and a mounting centre-to-centre measurement of 173mm. It is a Mando unit style and is sold as a new replacement alternator, not a remanufactured unit.

For buyers comparing fitment details, the key checks are the 12V system, 80 amp output, twin leg mount, 4 groove pulley, and the physical mounting dimensions. The note also states it may require external battery sense to be connected to the S terminal of the regulator plug if that terminal is currently blank with no wire.

Application and Buying Notes

Before ordering, match the part number MXA304 and check the physical layout against your vehicle’s existing alternator. The important dimensions here are the 55mm inside mounting legs, 8.5mm pivot hole diameter, M8x1.25 adjusting hole, and 173mm mount centre-to-centre measurement. If these do not line up with the alternator already fitted, the unit is unlikely to be a direct swap.

Electrical setup matters just as much as the bracket pattern. This alternator is a 12V, 80A unit with an internal regulator and a 4 groove pulley. Make sure your vehicle uses the same voltage, output requirement, pulley type and belt arrangement before buying, particularly where the original unit uses a different groove count or regulator arrangement.

The note about external battery sense is worth checking on the vehicle before installation. If the regulator plug currently has a blank S terminal with no wire, the unit may require that battery sense connection to be added. That is a wiring detail to confirm in advance so the alternator can be installed and connected correctly.

Warranty cover is listed as 3 years for passenger use and 1 year for commercial use. That does not change fitment requirements, so the part number, mount style, pulley section and electrical configuration should still be checked carefully against the original alternator and vehicle application.

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 MXA304 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.

For part number MXA304, the normal identification sequence is part number, electrical rating, mounting arrangement, connector or terminal style, and pulley or drive details. Using those checkpoints helps confirm that the listed unit matches the service requirement rather than only looking similar.

For a alternator in workshop, fleet, trade, agricultural, or construction service, the listed voltage 12 and output 80 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include HYUNDAI ACCENT, HYUNDAI ACCENT 2000, HYUNDAI ACCENT 2001, HYUNDAI ACCENT 2002, KIA CERATO, KIA CERATO 2004. Even with application listings, final confirmation should still be based on the exact unit being replaced and the service requirements of the vehicle or machine.

Compatibility note: Confirm fitment by matching part number MXA304, pin code IR49, the 12V 80A specification, twin leg mount, and the listed mounting dimensions against the vehicle already fitted. If the regulator plug has a blank S terminal, check whether external battery sense connection is required before installation.
