Loose power connection could easily cause it. I would clean and tighten the connections then see if anything comes back on. The worrisome part is that if the alternator was getting an intermittent connection it could have damaged it.
It may have damaged the radio as well. Dome lights are a different part of the switch than the head and marker lights so it is possible it is the switch, however the radio is not powered from that switch.
