Pokeys fan issue resolved, keeping the bus, generator rebuild?

[davidkerryedwards]

The later MB model 123 cars with the 616 and 617 (4&5 cylinder)
engines had the newer pencil type plugs. I believe the change was
made between 80 and 82 or somewhere in there. My 77 300d with the
617 had loop type originally. The 617 in my 85 300TD had the pencil
type originally.
