Application and Buying Notes

When comparing this alternator to the part already fitted to the vehicle, check the 12V system requirement and the 120A output rating first. Those two numbers need to align with the vehicle’s charging setup, and the Bosch part number 1986A00843 should be matched against the original unit where possible.

The fitment information provided points to IVECO and IVECO Daily applications, including Daily model years from 1999 through 2006. Even so, alternator fitment can vary within a model range, so a visual match and part number check remain important before purchase.

This is a rotating electrical component, so correct installation and system condition matter. If the battery, wiring, belt drive, or regulator-related circuit has an existing fault, those issues should be checked during diagnosis rather than assuming the alternator alone is responsible.

The 12 month warranty applies to the part as supplied, but warranty protection does not replace the need to verify compatibility. Using the Bosch brand, the 12V 120A rating, and part number 1986A00843 together gives the clearest buying reference for this unit.

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 1986A00843 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.
