Note:This is a 90A Alternator That Looks Like the 14778, Except the Bottom "Spool" Mounting Hole is 10mm (Rather Than 8mm), and There is a "W" Terminal on the Rear (of the 14821). This Unit Uses the 1/4" Spade Terminal for the D+ Output Like the 14778 (Rather Than the 5mm Stud, Like the 14396). The Same Unit as the 14821, Except Without the "W" Terminal (But With the 10mm Mounting), is the 13374 (This Does Use the 5mm D+ Stud, However).
