73 Challenger wiring questions

I have a unique wiring problem and I'm absolutely stumped. I have a rallye dash with a 5in tach mounted on the column and a pod of gauges mounted under the dash (water temp, oil pressure, volts). All gauges work but I have no turn signals, dash lights (std. gauges in cluster), gauge lights (ie. tach and pod), and no radio. The hazard lights still work both in car on the cluster and outside of the car with all of the lenses. If I keep replacing the 30amp fuse it will all work for a few seconds and when I get going, I will lose the above mentioned and the car will quit running and refuse to fire.
