Starter Relay 4 pin 12v/30A - Vespa LX, GTS 250/300

Premium 4-Pin 12V 30A Starter Relay

Eliminate the frustration of a completely dead starter button or a hollow clicking noise when trying to fire up your motor. This premium aftermarket 4-pin 12V 30A starter relay acts as the heavy-duty power switch connecting your battery directly to the starter motor. Engineered to withstand high-current electrical draws without freezing, sticking, or melting, this direct-fit replacement restores instant electrical continuity to your ignition system.

Key Features

• Heavy-Duty 30A Contacts: Rated to handle consistent 30-amp electrical loads, preventing internal contact welding and premature relay burnout.

• Plug-and-Play Integration: Designed with standard 4-pin terminal blades that slip directly into your factory wiring harness socket with no modification.

• OEM-Spec Performance: Manufactured to replicate the exact electrical activation resistances and load capacities of original part number 583684.

• Hidden Fitment Matrix: Beyond Vespas, this compact, universally configured 4-pin relay matches the electrical footprint of dozens of Piaggio, Aprilia, and Gilera scooters.

Maintenance Note: Relays generally fail in one of two ways: they go completely “open” (nothing happens when you hit the starter button), or they weld closed (the starter motor stays running continuously even after you let go of the button or turn off the key). If your starter motor stays stuck “on,” pull this relay immediately to prevent cooking your starter and draining your battery.

Installation Tip: Depending on your scooter model, this relay is typically packaged under the floorboard battery box cavity or behind the rear frame glovebox fairings. Make sure the battery terminals are entirely disconnected before plugging in the new unit to avoid throwing an accidental spark across the loom.

Pro Tip: If your scooter turns on but won’t crank, check the small 10A fuse located immediately adjacent to this relay block on the main wiring loom before replacing the relay itself. A simple blown accessory or ignition fuse will mimic a failed relay core perfectly!
