Product Details & Fitment
Part number RD3679 is the genuine square-bodied RA5 alternator conversion for early Bentley MkVI and R Type models from 1945-1955, approximately B2CF to B425CF, with a negative earth electrical system.
Designed to retain the appearance of the original dynamo, this alternator conversion provides a considerable output advantage while being substantially lighter than the original unit. Its design combines classic appearance with improved charging efficiency.
The unit is designed as a direct replacement for the original RA5 dynamo and features an internally regulated alternator. Installation requires the original regulator box to be bypassed, or it can be replaced with a dummy bulkhead-mounted regulator box.
Manufactured from billet, the alternator is designed to provide a reliable and efficient charging solution while preserving the authentic appearance of the vehicle's original electrical system.
Please verify the part number, vehicle application, and negative earth configuration before ordering. Professional installation is recommended to ensure the alternator conversion and charging system are correctly fitted.
