Just finished install of SC and tach bounces, fan runs, and multi-function relay box (black box) on rad. overflow bottle buzzes and starter won't kick over or start. Sounds like a short somewhere,but where? Install of SC requires move of black relay box from overflow bottle to pass side with a ground, ground is OK., Moving the front cover of the alt. to different direction. and numerous other changes. Any ideas? I've changed so much.
