Lucas Dynamo C40 & C40L
Lucas Dynamos
These are the original Lucas B90 dynamos which have been remanufactured in the UK
Although remanufactured, they are an outright not exchange purchase and no surcharge is levied
These C40 Lucas units were fitted to many Britich vehicles in the 1960 & 70s. They can also be fitted in place of the earlier C39 dynamo
C40L units are the same units in a slightly longer case (L standing for long) thus allowing more windings and a greater output. They were factory fitted to a few vehicles as below, but were often offered as an alternative (more expensive) version by dealers or for (usually cold climate) export markets. They are a common upgrade today for owners seeking a little more output from the charging system. The Lucas part number is LRD102
C40 Output 15Amp +/-1Amp at 4500 Rev
C40L Output 20Amp +/-1.5Amp at 4500 Rev

Je pense que c' est bien une 12V.
Diamètre de poulie?=> FEM proportionnelle à Oméga pour i exc. donné.
Petite question subsidaire : sur la dynamo il est est gravé "negative earth", le passage à la masse au moins me permettrait-il de résoudre mon pb
Non, pas le pb.
Ici, vérifier i exc et vitesse rotation.
Si elle fournit 6,7V => machine fonctionnelle.
Essais à vide et essais en charge sur lampes faciles à faire.
