Description
Overview:
This genuine Stephill diode (OEM 028-0026) is a small but critical electrical component used in Stephill portable and site generators, including GE2501 and GE3300. Built around a robust silicon semiconductor element with durable encapsulation and metal terminations, it allows current to flow in one direction while blocking reverse flow. In service it rectifies and protects the generator's excitation/charging circuits, helping to stabilise output and guard against voltage spikes. As a direct-fit Stephill part, it maintains correct performance and reliability across a wide range of models. Choosing the correct diode keeps the alternator and associated control gear working smoothly, reduces downtime, and supports consistent voltage under varying loads in demanding on-site conditions.
Key Features:
- Genuine Stephill part for assured compatibility and fit
- Direct replacement for OEM number 028-0026
- Supports stable rectification in exciter and charging circuits
- Helps protect windings and control electronics from reverse current and surges
- Durable encapsulated construction suited to heat, vibration, and regular generator use
- Compact form factor for straightforward access and installation
- Clearly defined connections to aid correct orientation and wiring
- Suitable for routine maintenance or fault repair to restore steady generator output
Typical Applications:
Used in Stephill generator alternators to provide rectification for the field/exciter circuit, maintain stable voltage, and protect against transient spikes. Ideal when refurbishing older sets, resolving no-charge or unstable-output faults, or completing preventive maintenance on generators used for site tools, lighting, pumps, and garden or grounds equipment where reliable power is essential.
