The Bomag 05726898 Rectifier is a genuine OEM component designed for Bomag BW-series single drum rollers and walk-behind rollers, including the BW 213 D, BW 212 D-2, BW 213 D-3, BW 213 DH-3, BW 216 D-3, BW212D 3, BW 6, and BW 6 S. Sourced directly from Bomag, this rectifier carries the correct electrical output specification to match the charging system your machine was built with. This is a direct OEM replacement that installs in place of the original unit with no alterations to existing wiring or mounting points. If your roller is showing signs of battery drain, erratic charging, or electrical system faults, replacing a failed rectifier with part number 05726898 restores proper system function.
Key Features
- Correct Output Specification — matched to the original charging system voltage and amperage output of the BW-series roller, ensuring the battery and electrical components receive the right charge.
- Genuine Bomag OEM Part — manufactured to the same standard as the original, with verified diode configuration and housing tolerances for long service life in demanding compaction environments.
- Broad BW-Series Fitment — fits BW 213 D, BW 212 D-2, BW 213 D-3, BW 213 DH-3, BW 216 D-3, BW212D 3, BW 6, and BW 6 S single drum and walk-behind rollers.
- Direct Drop-In Replacement — connects to the existing wiring harness and mounts in the original position, making the swap straightforward for field or shop technicians.
- Protects the Electrical System — a properly functioning rectifier prevents AC voltage from reaching DC-sensitive components, protecting the battery, instruments, and control circuits from damage.
The rectifier converts alternating current (AC) produced by the alternator into direct current (DC) that the battery and electrical system can use. Without a functioning rectifier, the charging system cannot maintain battery voltage, leading to power loss, failed startups, and potential damage to sensitive electronic components. A worn or failed rectifier often presents as a battery that drains quickly or an alternator warning light — replacing it promptly keeps the roller's charging system operating as intended.
