Hi All
Thanks for all the responses.
Graham, I’m aware of problems with earthing the Bakelite base plate of DJ and DK distributors. I believe the earthing is reliant on a thin brass strip in the Bakelite and brass sleeves in the bolt holes. Eddie Loader wrote an article on this in both the Hereford and South Wales club magazines. However the DS4 has a steel baseplate and should have a good ground between it and the body.
As John says there is a requirement for the DS4 to rotate in the dynamo end piece to achieve advance and retard. This means there is no positive clamping position where an earth connection between the distributor and dynamo can be achieved and earthing is reliant on moving components.
It is good to know that others have used earth cables on the distributor and I will devise an earth cable route. As Jim has mentioned the head of the dynamo through bolt looks a good place to attach it.
Cheers
Howard
