from of clamp "+B" and connected clamp "+D". Such condition when increas-
ing the revolutions may cause an exceptionally high alternator voltage which
would damage semiconductors!

age with this intervention!
Mind the perfect electrical joint on connecting clamps and on perfect alterna-
tor grounding!
