The Bomag 05748859 Rectifier is a genuine OEM component designed for the BW 900-50 walk-behind light roller. Sourced directly from Bomag, this rectifier delivers an exact fit and correct electrical specification for the charging system on your machine. This is the same part installed at the factory, ensuring compatibility with the BW 900-50's electrical architecture. If your machine is showing signs of charging failure or battery drain, this rectifier is the correct replacement to restore proper operation.
Key Features
- OEM Electrical Specification — meets the precise voltage and current rating required for the BW 900-50 charging circuit, eliminating the guesswork of cross-referencing aftermarket alternatives
- Direct-Fit Replacement — engineered to swap in using existing mounting points and wiring connections on the BW 900-50 walk-behind light roller
- Verified Fitment — confirmed for the Bomag BW 900-50, so you can order with confidence knowing this is the correct part for your machine
- Charging System Integrity — a functioning rectifier converts AC output from the alternator to stable DC power; a failed unit leads to battery drain, erratic electrical behavior, and machine shutdown
- Genuine Bomag OEM Part — supplied under part number 05748859 and backed by Bomag's OEM supply chain for consistent quality and availability
The rectifier is a critical component in the machine's charging system. It converts the alternating current (AC) produced by the alternator into the direct current (DC) needed to charge the battery and power the machine's electrical systems. When the rectifier fails, the battery cannot maintain a charge, leading to starting problems, loss of electrical function, and eventual machine shutdown. Replacing a worn or failed rectifier with the correct OEM unit restores proper charging output and protects the rest of the electrical system from voltage irregularities.
