Wacker Neuson 5000153278 Voltage Adjust Rheostat

The Wacker Neuson Voltage Adjust Rheostat is a genuine OEM component designed for the G-series portable generator lineup, spanning skid-mounted, cold-weather, and custom mobile configurations from the G12 through G160 models. As a direct OEM replacement, part is manufactured to the same electrical specifications as the original, ensuring accurate voltage regulation across the full output range of your generator. Confirmed fitment includes the G25, G50, G70, G85, G110, G120, G125, and G160 generator series — covering both standard skid-mounted and cold-weather variants. Keeping this component in proper working order is critical to protecting connected equipment and maintaining stable power output on the job.

Key Features

• Correct Resistance Specification — Matched to OEM electrical tolerances for accurate voltage adjustment across the full output range of your G-series generator.
• Genuine Wacker Neuson OEM Part — Sourced directly from Wacker Neuson, this component meets the same design criteria as the part originally installed at the factory.
• Broad G-Series Fitment — Confirmed for G12, G25, G50, G70, G85, G110, G120, G125, and G160 models, including skid-mounted, cold-weather, and custom mobile generator configurations.
• Stable Voltage Output — A correctly functioning rheostat allows the operator to fine-tune output voltage precisely; a worn or failed unit causes voltage drift that can damage sensitive connected loads.
• Electrical Safety Relevance — Voltage regulation components directly affect output stability; using a correctly rated OEM replacement reduces the risk of overvoltage or undervoltage conditions that can harm equipment or create hazards on site.

The voltage adjust rheostat is a variable resistor wired into the generator's automatic voltage regulator (AVR) circuit. By turning the rheostat, the operator can trim the generator's output voltage up or down to meet the requirements of the connected load or to compensate for line conditions. When the rheostat wears out or fails, voltage output becomes unstable or drifts outside the acceptable range — leading to flickering lights, tripped breakers, or damage to sensitive tools and equipment powered by the generator. Replacing a faulty rheostat with a correct OEM unit restores precise manual voltage control and protects both the generator and whatever it's powering.
