Can anyone tell me if the carbon brushes of Filko E45X the right replacements are for the autolite GBW2012AS carbon brushes.

Hans I couldn't give you an answer on your question, but your 38 super 8 doesn't have an alternator (dynamo), it's a generator. I'm not an electrician but I think it has to do with the positive ground.

Cars with generators come both ways, positive and negative ground. The generator doesn't care, there is a procedure for setting the polarity after working on the charging system. This is described on other threads on this website, use the search function.

In a generator the rotating member,":armature" is a series of copper coils wound around a ferrous core that rotates inside a series of magnets producing direct current. In an alternator the magnet is the rotating member. The current from a rotating magnet reverses the direction of the current in the coils as if routes inside them. The current then passes through diodes i to sort this out into one polarity. Clear as mud?

I suspect my friend Owen Dyneto may have the reference materials to answer your parts question. He is currently enjoying the Packard Club national meet in Traverse City, Michigan, so I would expect a response after this coming weekend

BDC,

In the Dutch language there is no distinction between a dynamo and a generator it is both a machine which generates electricity, in General, a dynamo is small, and a generator is big.
A dynamo is placed on a bicycle and a generator is placed in a ship.
Sorry for the misunderstanding.

Regards

Hans there's certainly a difference between the 2 in the Dutch language. Here's a Dutch explanation of what John Harley said above:

Generatoren

In auto's worden producenten verbonden door een katrol aan de aandrijfas. Deze katrol draait een draadspoel, genaamd het anker, in een magnetisch veld.

Dynamo

Dynamo's werken op dezelfde manier generatoren. Het belangrijkste verschil is dat in een dynamo de armatuur is statisch en de magneet wordt geroteerd om de huidige productie.
