Application and Buying Notes

The most important match point on this Bosch alternator is the part number 1986A00948, followed by the 12V system rating and the 200A charge current. Those three details need to align with the vehicle’s original charging setup before ordering, because alternators with similar housings can still differ in output, mounting, or internal configuration.

The alternator is listed as direct fastening and as an alternator type excl. vacuum pump. That means the physical mounting style and the presence or absence of a vacuum pump are both relevant checks. If the removed unit does not match those details, do not assume interchangeability based on appearance alone.

If the charging system is being repaired due to wear, it is sensible to inspect the V-Belt or V-Ribbed Belt at the same time, as that is the recommended additional repair item. A worn belt can affect charging performance and may create repeat labour if it is left in service when the alternator is replaced.

For buyers comparing options, the 200A output is the key electrical specification here. It indicates the alternator is intended for applications that require that rated charging current, but the vehicle application still needs to be confirmed using the part number and the exact alternator type rather than output alone.

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 1986A00948 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 a alternator in workshop, fleet, trade, agricultural, or construction service, the listed output 200 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Where no verified application list is available, the part number, mounting details, connector style, and published specifications should be used as the primary selection criteria.
