The Wacker Neuson Generator End Diode Kit is a genuine OEM component designed for the G25, G50, G70, and G85 portable and skid-mounted mobile generator series, as well as the HSH350 Hydronic Surface Heater and E1100 Ground Heater. As a direct OEM replacement, part is sourced to the same specifications as the original, ensuring correct electrical characteristics at the generator end. This kit covers an extensive range of configurations including standard, cold weather, extended run, custom, and Tier 4 Final variants across the G-series generator lineup.
Key Features
- Correct Diode Specifications for Your Generator End — Matched to the rectification requirements of Wacker Neuson G-series generators, ensuring the kit delivers the proper forward voltage and current rating for stable AC-to-DC conversion at the alternator end.
- Genuine OEM Part — Sourced directly from Wacker Neuson, this kit meets the same electrical tolerances as the original components installed at the factory, maintaining correct output voltage and protecting downstream electrical systems.
- Broad G-Series and Heater Compatibility — Fits G25, G50, G70, and G85 skid-mounted and mobile generators across standard, cold weather, extended run, custom, and Tier 4 Final configurations, as well as the HSH350 Hydronic Surface Heater and E1100 Ground Heater.
- Protects Alternator Output Integrity — A failed or degraded diode in the generator end allows AC current to pass into DC circuits, causing voltage fluctuations or complete loss of output. Replacing with part 5000176415 restores clean, rectified power delivery.
- Electrical Safety Compliance — Correct diode specification prevents uncontrolled voltage feedback into the exciter and regulator circuits, reducing the risk of further component damage and protecting connected equipment and operators.
The diodes at the generator end of an alternator form part of the rectifier bridge that converts the AC voltage produced by the rotating windings into the stable DC output used to excite the field coil and regulate output voltage. When one or more diodes in this assembly fail — due to heat stress, voltage spikes, or age — the generator may produce fluctuating voltage, reduced output, or no output at all. Replacing the diode kit restores the rectifier bridge to correct operation, allowing the generator to deliver steady, regulated power to connected loads and protecting the voltage regulator from unbalanced input.
