    Which post (wire) is reading 8V when running? Normally you should see battery voltage while running , if alt is not charging, 8V would tell me either bad cells in battery , or excessive corrosion in wiring/connection(s). Get circuit info so you know what to expect. Fully SLOW charge the battery and then test , before putting on more parts.
