It is listed as a single-leg alternator with an internal regulator, a 5-groove pulley, and a 59mm pulley outside diameter, which are the main checks to make before ordering a replacement.\u003c\/p\u003e\n\u003cp\u003eThe mounting details are specific: 160mm mount centre-to-centre, 58mm mount leg thickness, 10mm pivot hole diameter, and M8 x 1.25 adjusting hole diameter. Those dimensions matter when you are matching the alternator to the bracket and mounting hardware already on the vehicle.\u003c\/p\u003e\n\u003cp\u003eApplication notes supplied for this part state it suits Holden Nova and Toyota Corolla vehicles with 4A-FC, 6A-FC, 7A-FE, and 4A-FE engines.

The pulley is 5 groove with a 59mm outside diameter, so belt alignment and pulley style should also be checked against the existing unit.\u003c\/p\u003e\n\u003cp\u003eThe internal regulator is another important check, particularly when replacing a failed alternator rather than updating other charging system components. If the vehicle already runs an alternator with a different regulator arrangement, pulley configuration, or mount style, the part number and physical dimensions should be matched carefully before installation.\u003c\/p\u003e\n\u003cp\u003eThis unit is described for Holden Nova and Toyota Corolla applications with 4A-FC, 6A-FC, 7A-FE, and 4A-FE engines. That engine and application detail is useful, but it should still be confirmed against the vehicle’s existing alternator and the exact build details of the car, as similar models can use different charging components.\u003c\/p\u003e\n\u003cp\u003eBefore 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.\u003c\/p\u003e\n\u003cp\u003eFor workshop, fleet, and equipment applications, accurate identification of part number BXT1230A helps avoid unnecessary freight, additional labour, and vehicle or machine downtime.

Pulley configuration is 5 Groove. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.\u003c\/p\u003e\n\u003cp\u003eFor part number BXT1230A, 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.\u003c\/p\u003e\n\u003cp\u003eFor a alternator in workshop, fleet, trade, agricultural, or construction service, the listed voltage 12 and output 70 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.\u003c\/p\u003e\n\u003cp\u003eAvailable application references include HOLDEN NOVA, HOLDEN NOVA 1989, HOLDEN NOVA 1990, HOLDEN NOVA 1991, TOYOTA COROLLA, TOYOTA COROLLA 1987.
