OVERVIEW

Restore Charging Performance with the Miller 064846 Regulator

The Miller 064846 Voltage Regulator is the definitive replacement solution for charging system issues in Onan-equipped Miller welding generators. If your welder is failing to keep its battery charged, or if you are experiencing voltage spikes that threaten your machine's sensitive electronics, a faulty regulator is often the culprit. This unit effectively manages the output from the engine's stator, rectifying it to a clean 12V DC signal suitable for maintaining your starting battery.

Designed for the professional repair of machines like the Bobcat 225G, Trailblazer 250G, and other legacy Miller engine drives using Onan powerplants, this regulator installs directly into the existing wiring harness. It features the correct terminal configuration and mounting points, eliminating the need for wire splicing or modifications often required by universal "one-size-fits-all" regulators.

Keeping your charging system in top condition is vital for mobile welding operations. A reliable regulator ensures that your machine is ready to work when you are, preventing costly delays due to dead batteries. This Miller OEM part offers the peace of mind that comes with using factory-specified components for your critical equipment repairs.
