This section offers you a whole series of regulators for Ducellier alternators, Paris-Rhone alternators, Valeo alternators.

Always of high quality, our range covers a very large part of references.

When replacing the voltage regulator it is important to check the condition of the rotor, especially the copper collector, if it is too deep, the brushes will not be able to fulfil their role, in which case you can change the slip ring or rotor.
