Product Number: 7127-SEN-100A6G
The WAI 7127-SEN-100A6G is a brand-new 12V, 100-amp alternator. It is built to the Delco 10SI Series IR/EF specification — a design widely used across agricultural, plant, and classic vehicle applications. It is supplied as a direct replacement for the Powerite Automotive reference 7127SE105, making it straightforward to source as an OE-equivalent unit without the need for rebuilding or remanufacturing an old core.
Constructed to the 10SI internal-regulator/external-field (IR/EF) design standard, the unit operates with clockwise rotation and is fitted with a groove pulley to suit the original drive arrangement. At 100 amps output it delivers the charging capacity the 10SI platform was engineered for, supporting reliable electrical system performance across the full load range of the vehicle or machine it serves.
The groove-pulley configuration is important at the point of fitment: confirm your existing drive belt and pulley arrangement matches before ordering. If you are unsure whether this alternator suits your application, use the selection widget or search our cross-referenced catalogue by OEM number or machine model. Ask Simon if you need further guidance — every confirmed fitment is backed by our Fit Guarantee.
