The Bosch AL8785X is a remanufactured 105-amp, 12-volt alternator for cars, rebuilt to Bosch specifications with an internal regulator, internal fan and a 6-groove pulley already fitted. It is a direct-fit replacement for the original unit on the applications Bosch lists, so the wiring plug and pulley grooves match without adapters. Remanufactured units cost less than new ones and keep the factory fit, but they carry a shorter warranty than new Bosch alternators and depend on the quality of the rebuild. It suits drivers replacing a failed alternator on a daily car who want OEM-style fit over a new aftermarket unit.

Owners of remanufactured Bosch alternators generally report a straight bolt-in fit and correct charging, with the pulley and plug matching the original. Complaints center on units that failed early or arrived with a bad regulator, and on the shorter warranty compared with new parts.
