Application and Buying Notes

Before ordering, match the part number 1986A00945 against the alternator currently fitted to the vehicle. The listing identifies a 12V, 150A Bosch alternator with a single pivoted lever fastening type and an alternator layout excluding vacuum pump, so those points need to line up with the existing unit.

The fitment information supplied covers Land Rover Discovery and model years from 1998 through 2004. Use that as a starting point only, then confirm the vehicle application by checking the alternator design, mounting arrangement and belt setup on the car you are working on.

A 150A rated alternator is not a generic cross-match item. The charge current figure listed here is 130A, so the electrical system specification should be compared carefully with the removed component. Matching the connector style, mounting points and vacuum pump arrangement is just as important as matching voltage.

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 1986A00945 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.
