OLIFANT Voltage Regulator Rectifier for Harley-Davidson – 74519-88/88A Compatible (Electra Glide, Dyna, Softail)

Overview

The OLIFANT Voltage Regulator Rectifier is designed to replace aging units on classic Harley-Davidson machines from the late 1980s through the 1990s. This compact module works to manage charging for the battery and electrical system, delivering a stable, reliable input as riding conditions change. Built for durability, it aims to help you keep essential components performing as intended on longer trips and daily commutes alike.

Engineered for a broad range of carbureted configurations, this regulator rectifier focuses on stability and dependability. While it can contribute to steadier voltage delivery during engine operation and at idle, it does not guarantee specific outcomes. Real-world riders often notice smoother electrical behavior and more consistent performance under diverse riding scenarios when used as a replacement for worn parts.
