The Wacker Neuson Voltage Regulator is a genuine OEM component designed for the RD15 series hydrostatic double drum vibratory rollers. Sourced directly from Wacker Neuson, this part meets the exact output specifications required to maintain stable electrical performance in your machine. It is a direct-fit replacement for RD15 rollers built to OEM drawings, ensuring correct installation without adaptation. Keep your roller running at spec with the part number your machine was built around —.
Key Features
- Correct Output Specification: — Genuine OEM construction ensures the voltage regulator delivers the precise regulated output your RD15's electrical system requires — no guesswork on compatibility.
- Direct-Fit Replacement: — Engineered to match the original mounting configuration and wiring connections on RD15 series rollers, allowing straightforward swap-out during service.
- RD15 Series Fitment: — Confirmed fitment for RD15 hydrostatic double drum vibratory roller models, covering both 5000008057 and 5000009316 build configurations.
- Protects the Charging System: — A properly functioning voltage regulator keeps alternator output within safe limits, protecting batteries, sensors, and control electronics from voltage spikes or undercharge conditions.
- Electrical Safety Assurance: — As a critical component in the machine's charging circuit, using a genuine OEM voltage regulator helps prevent erratic electrical behavior that can affect roller controls and operator safety.
- Genuine Wacker Neuson OEM Part: — Supplied under the original Wacker Neuson part number 5000203000, so you can order with confidence that you're receiving the same component used in original production.
The voltage regulator controls the output of the alternator, ensuring the machine's electrical system receives a steady, consistent voltage regardless of engine speed or load. Without a correctly functioning regulator, the charging voltage can fluctuate — running too high risks damaging sensitive electronics and the battery, while running too low leaves the battery unable to hold a charge and can cause the machine to shut down unexpectedly. On a hydrostatic double drum vibratory roller like the RD15, where hydraulic controls and compaction monitoring rely on stable electrical supply, a failed voltage regulator can quickly take a productive machine out of service.
