The dynamo or dynamoelectric machine was the ancestor of the alternator, the dynamo is coupled to a voltage regulator, and dynamo, dynastar assemblies are still found today on some engines and machines.

The former dynamos Bosch, Ducellier, Sev Marchal, Paris-Rhone in particular equipped many models of cars, trucks and tractors.

This one is composed of an armature, inductors or set of coils, bearings, set of brushes or carbon and on the end a pulley allowing the connection to the motor via the belt.

It is always very important to test the dynamo and the regulator, both should be repaired or changed together if necessary.

The dynamo or dynamoelectric machine is the ancestor of the alternator. The dynamo is coupled to a voltage regulator. We still find today dynamo Dynastarter assemblies on some engines and agricultural or construction machinery.

The old Bosch, Ducellier, Sev Marchal and Paris-Rhone dynamos equipped many models of cars, trucks and tractors.

The dynamo is composed of an armature, inductors or set of coils, bearings, a set of brushes or carbon and on the end of a pulley allowing to link the motor via the belt.
Technical information on dynamos

It is always very important to test the dynamo and the regulator. Both must be repaired or changed together if necessary.

The output of a dynamo can be tested with a voltmeter :

             Place a length of wire between the terminals of the dynamo.
             Connect your voltmeter between the terminals and "ground".
             Turn on the ignition and slowly accelerate to double the idle speed of your vehicle.
             If the dynamo is in perfect condition: the voltmeter will display between 12 and 14V.
             If the needle does not stabilize: carbon or switch may be the cause.
             If the voltmeter does not indicate anything: unplug the terminals; connect to "ground" and re-test.
