The Bomag 78102327 Wiring Kit is a genuine OEM electrical assembly designed for BW 135 AD, BW 138 AD, BW 138 AC, and BW 138-AD tandem rollers. Sourced directly from Bomag, this wiring kit carries the correct connectors, routing, and wire gauges to match the original harness exactly — no splicing, adapting, or guesswork required. This kit confirms fitment across the BW 135 AD and BW 138 series tandem rollers, giving you confidence that the replacement matches what came off the machine. When electrical issues arise on these compactors, using the correct OEM wiring kit is the straightforward path to restoring full system function.
Key Features
- OEM-Correct Electrical Specification — manufactured to Bomag's own wiring standards, with matched wire gauges, insulation ratings, and connector types specific to this tandem roller platform
- Direct Plug-In Replacement — connectors and harness routing align with the original mounting points on BW 135 AD and BW 138 series tandem rollers, allowing a clean, straightforward swap
- Confirmed Tandem Roller Fitment — verified for the BW 135 AD, BW 138 AD, BW 138 AC, and BW 138-AD, covering key variants in Bomag's mid-size tandem roller lineup
- Protects Downstream Electrical Components — a correctly specified wiring kit prevents voltage irregularities and shorts that can damage control modules, sensors, and other electrical components throughout the machine
- Electrical Safety Compliance — using the genuine OEM harness maintains correct circuit protection and insulation integrity, supporting safe operation of the roller's electrical systems
The wiring kit provides the complete set of electrical conductors, connectors, and harness components that carry power and signals between the engine, controls, and operating systems of the tandem roller. A functioning wiring harness is essential for reliable starting, instrument operation, and control response — deteriorated or damaged wiring can cause intermittent faults, failed sensors, or complete electrical shutdowns that halt production. Replacing a worn or damaged harness with a genuine OEM wiring kit restores the integrity of the entire electrical circuit and returns the machine to correct operating condition.
