I'm curious to see a visual of how this originally was?
the terminals moved to the compressed cardboard brush plate.
, as I have the ally cover on an earlier body, which I think does have a groove for an 'O' ring, so maybe not much earlier..??
It's a bit busy/crowded in there with bullet connectors in use..!
I suggest that the two wires in question are attached to the cover as an earth connection, but not a very good (soft) one...?? My piccie shows where they should attach to.
Also B'macc, Question- I know we've been over this before, but I'm thinking to switch to -ve Earth, to save me confusion, so just checking as you say only the Field wire needs to connect to '-ve' battery? I've been told all kinds of things over the years mainly join 'D' and 'F' for polarizing also. Does it matter if 'D' joins the party or not?
It just seems too easy, makes me suspicious..!!
