Royal Enfield 144355 – Ammeter 12V with Coupler (Old Bullet Nacelle Meter) for Standard 350, Bullet 500, Deluxe, Machismo, Campus & Electra 4S KS

Royal Enfield part 144355 is the classic “AMMETER 12V WITH COUPLER / SOCKET” used in the headlamp nacelle of old-model Bullets. The official Royal Enfield part-number handbook lists 144355 – AMMETER 12V WITH SOCKET 350CC, confirming it as the OE charging-indicator gauge for 350cc Bullets.

This ammeter mounts into the top of the headlamp nacelle and connects via the supplied coupler/socket to your wiring harness. It shows charging/discharging of the battery at a glance, helping diagnose weak batteries, faulty regulators or alternator issues on older CI/AVL Bullets.

Ideal for restorations, OE-style rebuilds and daily riders where the original meter has faded, cracked, filled with moisture, or stopped responding.

🔴 Not designed for UCE/J-Series consoles, Himalayan, or 650 Twins. Use only on confirmed old-model platforms or as a custom retrofit with an experienced electrician.

It is the classic 12V ammeter with coupler/socket used in the headlamp nacelle of older Royal Enfield Bullets. Official documentation calls it “AMMETER 12V WITH SOCKET 350CC”, and Bike-Parts-RE lists it as a genuine part, same as factory-fitted.

Dealer data shows 144355 on Standard Bullet 350, Deluxe, Machismo, Campus, Electra 4S-KS and Bullet 500 (CI) – all old-model CI/AVL Bullets with nacelle-mounted meters.

Q3. Can I use this ammeter on a Classic 350/500 UCE or new J-Series Classic?
Those bikes use different meter consoles and part numbers. There’s no OEM or catalog proof that 144355 is plug-and-play there, so we do not recommend or guarantee it. You may use it only as a custom retrofit after checking dimensions and wiring with a qualified electrician.

Yes. Listings clearly call it “Ammeter 12V with Coupler/Socket”, and both Bike-Parts-RE and The Spares Company show it supplied ready to plug into the harness.

Q5. Is this a genuine RE part or aftermarket?
144355 is a genuine Royal Enfield part number. Some stock on the market is RE-packaged; others are OE-equivalent (e.g., ENFIELDGP) built to the same spec. Your product page can mention: “Genuine or OEM-equivalent based on batch – always matched to part no. 144355.”
