1970 Dodge Dart Problems

So took out the cluster to inspect the gauges. There was a positive and negative charged wire on the alternator gauge. While i was sifting through things one of them sparked. I tried to put everything back together and now nothing is working. No lights, nothing on the dash, and car won't start. Can i fix it? or is my car a goner?
