Re: Sad dynamo

Thanks Simon. As it happens, I already had a copy of that but I had forgotten where I'd put it. I need a better filing system.

Does anybody know what the resistance down to earth should be for the field coil and the armature for the E3L?

Sad dynamo

I have in my possession a nice pre-war VH with a dynamo that sort of works but only manages to squeeze out a fraction of a volt at idle and about 1.6 volts when revved. Not enough to stimulate the interest of the voltage regulator. The brushes look OK and seem to be making contact with the commutato...

Re: Rocker box thread

Well, it looks like I may know the answer but I would appreciate some confirmation. I think it is 5/16" BSCY (26tpi). Does that sound right?

Rocker box thread
