Yet Another "No Dash Lights" Problem

Yes the red is power going in the ALT' gauge. Black is power out to everything, not a ground wire. Without black connected nothing works. Even with black connected and power to the fuse box, etc.. the inst' panel will need to be grounded before the lights will work. ( actually, oil lamp and BRAKE would work since they ground at their remote switches ). Anyway... When the panel dangles from its harness connectors it is not chassis grounded.
