Application and Buying Notes

Before ordering, match the part number 1986A00782 against the unit being removed, then confirm the vehicle uses a 12V charging system with a 90A alternator. The alternator type is excl. vacuum pump, so this is an important check where the engine bay layout or accessory equipment differs.

The mounting detail is listed as double pivot lever fastening type. That means the physical bracket arrangement should be checked carefully, not just the electrical rating, because alternators with the same amperage can still differ in fitment and mounting style.

The fitted application list includes Seat Ibiza, Skoda Fabia, Volkswagen Polo, and Volkswagen Transporter / Caravelle variants. Even where a model name appears, year range and engine configuration still need to be checked against the vehicle, because fitment can vary within the same model line.

Packaging dimensions are 23.9 x 20 x 20, and the unit is sold each. Those details are useful when planning freight handling and workshop storage, but the key buying decision should still be based on voltage, amperage, mounting type, and the vehicle application details.

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 1986A00782 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.

Using those checkpoints helps confirm that the listed unit matches the service requirement rather than only looking similar.

For a alternator passenger in workshop, fleet, trade, agricultural, or construction service, the listed voltage 12 and output 90 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include SEAT IBIZA, SEAT IBIZA 1995, SEAT IBIZA 1996, SEAT IBIZA 1997, SKODA FABIA, SKODA FABIA 2007. 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.
