Bosch Alternator 12V 65A BXF1230A

This Bosch alternator is a 12V, 65A unit with part number BXF1230A, supplied new as an each item and fitted with an internal regulator. It is listed with a twin leg alternator mount, 68mm inside mounting legs, a 175mm mount centre-to-centre measurement, and a 72mm pulley outside diameter, so the physical mounting points matter as much as the electrical rating.

The unit is described as Bosch-made and suited to Bosch applications, with an A section pulley and an M10 pivot hole plus an M8 x 1.25 adjusting hole. Those dimensions are useful when checking whether the alternator will line up correctly with the existing brackets, belt arrangement, and adjustment hardware on the vehicle.

As a rotating electrical component, this alternator is specified at 65 amps and 12 volts, with a recorded weight of 9.21kg. The product also carries a one year warranty, which gives a clear service period for normal retail supply, but final suitability still depends on matching the part number and the application details before purchase.

Application and Buying Notes

The most important checks on this alternator are the part number BXF1230A, the 12V system voltage, the 65A output rating, and the mounting measurements of 68mm inside mounting legs and 175mm centre-to-centre. If any of those differ from the unit already fitted to the vehicle, the alternator may not line up correctly or may not suit the charging system specification.

The pulley details also matter. This unit has a 72mm outside diameter pulley with an A section belt profile, so the belt type and pulley alignment should be checked against the existing setup. The pivot hole is M10 and the adjusting hole is M8 x 1.25, which are practical verification points when comparing brackets and fasteners.

Because this alternator uses an internal regulator, it is important to confirm the vehicle’s charging system arrangement before buying. A regulated alternator is not just a physical match; it also needs to suit the electrical configuration already in the vehicle. The listed weight of 9.21kg can also be a useful comparison point when checking against the removed unit.

If you are working from a worn or missing original alternator, compare as many details as possible: the Bosch branding, the BXF1230A part number, the twin leg mount, the pulley size, and the 12V 65A specification. These details are the safest way to narrow the match without relying on appearance alone.

The fitment list provided for this alternator covers Ford Laser, Ford Telstar, and Mazda 323 applications, with the preview spanning Ford Laser 1985 to 1994 and Mazda 323 1980 to 1990. Even where a model appears in the fitment data, it is still wise to confirm the exact application against the part number and the physical dimensions already listed here.

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 BXF1230A 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.
