The Bomag 64040127 Earth Ground Wire is a genuine OEM component designed for Bomag BW 161 AC-2, BW 161 AD-2, BW 164 AC-2, BW 164 AD-2, BW 202 AD-2, and BW 202 AHD-2 tandem rollers. Sourced directly from Bomag, this earth ground wire delivers an exact OEM match — right connector geometry, correct conductor gauge, and proper termination points — so it installs cleanly without modification. As a genuine OEM part, it meets the same electrical specifications as the wire it replaces, protecting sensitive onboard systems from stray current and grounding faults. If your tandem roller is showing erratic instrument behavior, electrical faults, or charging irregularities, a worn or broken earth ground wire is a common culprit worth checking first.
Key Features
- Correct Conductor Spec — genuine OEM construction ensures the wire carries the rated ground current without resistance buildup or voltage drop that can corrupt machine electronics
- Drop-In Installation — factory-matched termination points and connector geometry align directly with the original mounting positions on BW-series tandem roller frames
- Broad Tandem Roller Coverage — fits BW 161 AC-2, BW 161 AD-2, BW 164 AC-2, BW 164 AD-2, BW 202 AD-2, and BW 202 AHD-2 tandem rollers
- Electrical System Stability — a properly grounded machine keeps charging circuits, sensors, and control modules operating within spec, preventing nuisance faults and unplanned stoppages
- Safety-Critical Grounding Path — a compromised earth ground wire creates shock hazard risk and can damage onboard ECUs and charging components; replacing it with a genuine OEM part restores the intended protective circuit
The earth ground wire provides the low-resistance return path that completes every electrical circuit on the machine, anchoring the entire electrical system to the roller's chassis ground. Without a solid, intact ground connection, current has no reliable return route — leading to voltage spikes, sensor misfires, or damage to the alternator and control modules. A failed or corroded earth ground wire on a BW-series tandem roller often surfaces as unexplained warning lights, charging faults, or intermittent electrical failures that are difficult to trace until the grounding path itself is inspected and restored.
