The Bomag 78102702 Wiring Kit is a genuine OEM electrical harness assembly designed for Bomag tandem rollers across the BW 100, BW 120, BW 125, BW 135, and BW 138 series. Sourced directly from Bomag, this kit delivers the exact connector layouts, wire gauges, and harness routing required by the machine — no improvised splicing or adapter work. Compatible models include the BW 100 AC-3, BW 100 AD-3, BW 120 AC-3, BW 120 AD-3, BW 120 AD-3, BW 125 ACH, BW 125 ADH, BW 135 AC, BW 135 AD, BW 138 AC, and BW 138 AD tandem rollers. When electrical faults trace back to a degraded or damaged harness, replacing it with part number 78102702 restores clean signal paths and proper system operation throughout the machine.
Key Features
- Genuine OEM Electrical Integrity — factory-matched wire gauges, connector types, and insulation grades engineered specifically for Bomag tandem roller electrical systems, not a generic harness adapted to fit
- Drop-In Harness Routing — all connectors, looms, and terminations align to the original mounting points on covered models, keeping installation straightforward and connections secure
- Broad Tandem Roller Coverage — fits BW 100 AC-3, BW 100 AD-3, BW 120 AC-3, BW 120 AD-3, BW 125 ACH, BW 125 ADH, BW 135 AC, BW 135 AD, BW 138 AC, and BW 138 AD tandem rollers
- Restored System Communication — a fully intact wiring kit ensures controls, sensors, and safety circuits receive clean, uninterrupted signals, keeping all machine functions operating as designed
- Electrical Safety Compliance — correct insulation ratings and properly terminated connectors reduce the risk of shorts, chafing faults, or intermittent failures that can compromise operator safety and machine reliability
A wiring kit serves as the electrical backbone connecting the roller's controls, sensors, solenoids, and safety systems into a single integrated harness. Over time, heat cycling, vibration, and environmental exposure can degrade insulation, corrode terminals, or crack connector housings — leading to intermittent faults, warning light activations, or complete loss of function in specific circuits. Replacing a worn or damaged harness with the correct OEM kit ensures every circuit path meets the original specification, preventing the diagnostic guesswork that comes with improvised repairs or mismatched replacements.
