Product Description
Protect your motorcycle’s sensitive fuel injection and electronic components with the Genuine Royal Enfield Fuse Box Add-On. This OEM component (Part No: 147998/A) is an auxiliary harness and fuse holder specifically designed for the Classic 500 EFI models.
As the complexity of the Unit Construction Engine (UCE) increased with the introduction of Electronic Fuel Injection (EFI), Royal Enfield introduced this “Add-On” fuse box to handle the additional electrical load of the fuel pump, ECU, and sensors. The 147998/A assembly typically features a 6-wire configuration and serves as a modular expansion to the main wiring harness. It is built with heat-resistant plastic housing and weather-sealed connectors to ensure the fuses remain protected from moisture—preventing the common “misfiring” or “stalling” issues caused by corroded electrical contacts. If your Classic 500 is experiencing sudden power loss or EFI light errors, this add-on fuse box is often the primary point of inspection for blown fuses or burnt wiring.
Key Features:
-
OEM Electrical Safety: 100% Genuine Royal Enfield part, calibrated to handle the specific amperage required by the Bosch EFI system.

Modular “Add-On” Design: Engineered to integrate seamlessly with the existing harness, providing a dedicated space for auxiliary fuses.

Durable Protection: High-impact, flame-retardant housing designed to withstand the heat and vibration of the 499cc long-stroke engine.
-
