Key Features
- Genuine Honda OEM Electrical Assembly — sourced directly from Honda, this Control Box Assembly (10A) meets the original electrical specifications for the GX390, ensuring the control circuit functions as intended.
- 10A Rated Current Capacity — the 10A designation identifies this specific variant; confirm it matches the rating on your original unit before purchase, as alternative ratings are separate parts.
- Direct-Fit Replacement — designed as a drop-in replacement for GX390 horizontal shaft engines, with connector and mounting geometry that matches the original assembly.

The Control Box Assembly manages and protects the electrical output circuit on the GX390 engine, housing the key switching and overcurrent protection components that govern accessory or charging circuits. The 10A rating indicates the maximum continuous current the assembly is designed to handle, making the correct variant selection critical to proper operation. When this assembly fails or is incorrectly rated, connected electrical loads may not function, or the circuit may be left without adequate protection.
