The updated complete alternator replaces ALL the components of the Alternator and the rotor removal tool.

The high output design includes a European made stator and rotor with increased electrical output and paired with a modern diode board, and adjustable voltage regulator. The system replaces the under performing Bosch charging system with a 105mm outside diameter stator (timing cover side) used on early BMW Airhead's from 1970-1976. This EDL3 charging system will reach charging voltage sooner than any other BOSCH style charging system we offer.

Use the fitment table on the APPLICATION TABLE TAB BELOW to identify the correct kit size before ordering. You can measure the inside (timing cover side) and outside (stator frame side) diameter of your stator ring with calipers or use the BOSCH Alternator part number. Further instructions are included in the installation guide to verify the correct kit required.

Some customers report increased component failure when using LITHIUM Style batteries. These batteries are not recommended nor supported for warranty replacement of components. Conventional wet acid or sealed AGM (Absorbed Glass Mat) batteries are known to work well with all conventional charging systems. See our LITHIUM specific alternator EDL4Li for this alternative.
