Product Number: 8415N
The WAI 8415N is a brand-new 24V, 100A alternator. It is built to the Motorola / Prestolite 8SC Series IR/EF design, offering a direct OE-equivalent replacement for heavy-duty plant, commercial vehicle, and industrial applications. It replaces original-equipment numbers from Cummins, Renault, Valeo, Clark, Iskra, Mahle, and a range of other major manufacturers — 27 verified cross-references in total — making it a widely applicable unit across demanding fleet and workshop environments.
The 8415N is supplied brand new and features clockwise rotation. It is supplied without a pulley, so the original pulley from the outgoing unit should be transferred at installation. The IR/EF (internal regulator / external fan) architecture is consistent with the Motorola and Prestolite 8SC Series specification, ensuring electrical compatibility with the systems those original units served.
With a 100A output at 24V, this alternator is rated for the sustained electrical loads typical of heavy-duty diesel engines found in plant machinery, trucks, and agricultural equipment. Its specification aligns with OE units from manufacturers including Mack, ERF, Seddon Atkinson, Ingersoll-Rand, Carrier, and Leyland, among others.

The best way to find the correct starter motor is to combine the machine and engine details with the OEM or original starter reference, then confirm voltage, rotation, pinion teeth, mounting and terminal position. Do not choose a replacement from appearance alone.
A starter motor usually clicks without cranking because the battery cannot deliver enough current, resistance is present in the battery cables or engine ground, or the starter control circuit and solenoid are not operating correctly. A click does not automatically mean the...
