If you're maintaining or restoring the electrical system on your BW 900-50, this is the correct OEM part for the job.
Key Features
- Genuine OEM Electrical Spec — matched to the exact switching characteristics and terminal configuration of the original relay, ensuring correct circuit behavior in the BW 900-50 electrical system
- Direct Plug-In Replacement — designed to seat into the original relay position without modification, maintaining the integrity of the factory wiring harness
- Confirmed Fitment — verified for the Bomag BW 900-50 walk-behind light roller under part number 05767789
- Protects Electrical Circuits — a properly functioning marginal relay correctly manages switching loads, helping prevent damage to downstream electrical components from incorrect current flow
- Electrical Safety Compliance — using the correct OEM relay maintains proper circuit protection ratings, which matters for operator safety and machine reliability on site
A marginal relay is an electrically operated switch that controls one or more circuits within the machine's electrical system, activating or deactivating functions in response to an input signal. On a walk-behind roller like the BW 900-50, relays manage critical switching tasks — from engine control circuits to auxiliary functions — allowing low-current signals to safely switch higher-current loads. When a relay fails, the circuit it controls may become unresponsive or behave erratically, causing operational faults that can be difficult to diagnose without first ruling out the relay itself.
