Yet Another "No Dash Lights" Problem

Help! I have no dash/cluster lights in my 74 Duster. Just bought this car. Have no dash lites. I checked all my connections, all appear ok. Verified all fuses were good. I took out the cluster and replaced all the bulbs. Nothing. I have power to the red lead going to the AM-Meter. I checked for power at the fuse box. No power coming in. Unplugged the main harness under/near the steering column. No power. Where do I go next??
