For polarising the dynamo I will need a battery or any other DC 12V supply is enough ?

Fit a DVR3. I did and all your problems go away.

Which one should I choose ?  Could I load this old dynamo with 22 amps ?

Yes, 22amp one.  They are supplied both positive and negative earth, so make sure you specify the one you want.

Here’s some.  I put an inline fuse in for safety

Ok, thanks again

 

I am thinking about to replace the filed coil also

 

Where can I found a good one ?

[floormanager]

The field coil in the dynamo? I did it too, not straightforward.  Getting the original screws out of the dynamo was a challenge.  I mullered the screws, so had to drill them out.  Once the field coils were fitted, the commutator would not go in.  I had to spread the field coils with an exhaust pipe spreader.  Great when they are fitted but a bit of a pain to do.

Two things to note:

- Use the correct type and size driver which will be pozidriv which is totally different to phillips. Most fasteners on a mini or anything British are pozidriv, NOT phillips. It's something that most people don't know.

- there's a special tool to undo these screws sicne they are so difficult.

I ordered and paid a DVR3 unit 2 weeks ago but response since then.
