The ALU0028 is a high-performance, universal 1-wire alternator designed to simplify your vehicle's charging system. Based on the legendary GM 10SI platform, this unit features a built-in self-exciting regulator, meaning it requires only a single wire connected to the battery to function. It is the gold standard for hot rod enthusiasts, tractor restorations, and custom marine applications where a clean, minimal engine bay is required.
RELIABILITY: Engineered with high-temperature internal components and a heavy-duty rectifier to ensure consistent 63A output under demanding conditions.
Key Features
✔ 1-Wire Setup: No external regulator or complex wiring.
✔ Self-Exciting: Charges automatically as engine RPM rises.
✔ Internal Fan: Optimized cooling for long-cycle reliability.

Questions & Answers
Is this a genuine original part?
This is a premium quality aftermarket replacement part, manufactured by 4Drive to meet or exceed original equipment (OE) standards for fitment and performance.
How do I know if it is compatible?
If you are converting to a 1-wire system or replacing an existing 10SI alternator, this is a universal fit. Check the cross-reference list above for part number matching.
Will it charge at idle?
This self-exciting alternator typically requires a brief engine rev (to approximately 1200-1500 RPM) to "turn on" the charging circuit, after which it will maintain charge even at low idle speeds.
Note: Professional installation is recommended. Ensure the battery cable gauge is sufficient for a 63A output. Visit 4drive.co.uk for more technical support.
