The Wacker Neuson Generator Bridge Rectifier Diode is a genuine OEM component designed for GPS, GS, and G-series portable generators including the GPS9700, GPS8500, GS8.5V, GS9.7V, G3.3A, G4.6A, G5.6A, G25, G12, and G110 series. As a direct OEM replacement, part is sourced from Wacker Neuson's authorized supply chain, ensuring it meets the original electrical specifications for your generator. This rectifier diode is a critical charging system component — getting the right part matters for protecting both the generator and connected equipment. Confirm your model number before ordering to ensure this part matches your specific unit.
Key Features
- Genuine OEM Electrical Specification: — Manufactured to the original diode bridge output and voltage rating for Wacker Neuson generator charging circuits, ensuring correct AC-to-DC conversion without risk of under- or over-voltage to the system.
- Drop-In Replacement: — Mounts directly into the existing rectifier position with original connector and terminal orientation, requiring no wiring modifications.
- Broad Generator Family Coverage: — Fits GPS9700, GPS8500, GS8.5V, GS9.7V, G3.3A, G3.3AE, G3.7A, G4.6A, G4.6AE, GS4.6A, GS4.6AE, G5.6A, GS5.6A, G12, G25, G110, and related 50Hz and EPA-compliant variants.
- Protects the Charging System: — A functioning bridge rectifier keeps battery charging stable and output voltage consistent; a failed unit causes erratic charging, dead batteries, or loss of electric start capability.
- Electrical Safety Compliance: — Using the correct OEM-rated diode bridge prevents thermal overload and potential damage to downstream electrical components, keeping your generator operating safely within designed parameters.
The bridge rectifier diode converts the alternating current (AC) produced by the generator's alternator into direct current (DC) used to charge the battery and power the electric start system. It acts as a one-way electrical gate, allowing current to flow in only one direction to deliver steady DC output. When this component fails, the battery will not charge correctly, the electric start system becomes unreliable, and in some cases the generator may produce unstable output voltage that can affect sensitive equipment connected to it.
