Professional Restoration of the Original Murena 2.2 Ammeter One of the most common failure points on the Matra Murena 2.2S is the original ammeter. Over decades, the internal mechanisms often seize, the needle sticks, or the gauge simply stops reading, leaving owners guessing about their charging system status.

On this specific vehicle, we have undertaken a complete, professional restoration of the instrument. The unit has been fully disassembled, cleaned, and recalibrated to ensure it responds accurately to the electrical load. Unlike many “working” gauges found on the market that still suffer from sticky needles or inaccurate readings, this ammeter moves smoothly and provides precise feedback.

This restoration ensures that the driver can confidently monitor the alternator and battery health—a vital safety and reliability feature for any classic Matra owner. It is a perfect example of the attention to detail applied to this 2.2S, preserving the original dashboard aesthetic while guaranteeing modern reliability.
