Rebuilt Magneti Marelli voltage regulators for vintage Ferrari

Description

We stock rebuilt Magneti Marelli RTT 101A and RTT 101C voltage regulators, now available for outright purchase or with core exchange. These were original equipment on many 1960s and 1970s Ferrari models equipped with Magneti Marelli alternators. All our rebuilt regulators have original electronic components replaced with new parts, including the main transistors. Each regulator is bench tested after rebuilding to ensure full functionality. These are a great option if you would like to preserve your car’s original electrical system and appearance.

Disclaimer

Magneti Marelli regulators are only suitable for cars equipped with Magneti Marelli alternators. Some models listed above were also originally fitted with Lucas or Bosch alternators, which are not compatible with Marelli regulators. Additionally, many cars have been retrofitted with later voltage regulators or alternators with integrated regulators. Before installing one of these original regulators, we recommend thoroughly examining the electrical system and wiring to ensure compatibility.

The application information above is provided for informational purposes only and is based on our research. Actual historical factory fitment on an individual car may differ from the above due to rolling changes in specification and parts supply. If you are looking for a “concours correct” installation, we recommend consulting with the appropriate concours event judging committee to determine the correct part for your vehicle.

WARNING: Electrical systems are dangerous and improper installation can result in damage, vehicle malfunctions and, in extreme cases, personal injury. Installation by a qualified professional Ferrari technician is recommended.
