Wont start, no turn over or dash lights

DUDE! I literally just fixed this same problem yesterday. Check the battery terminals, if they're old, they may not be letting juice through. Its less than ten bucks to replace them. My negative connector was only letting a couple volts through. Happened rather suddenly as well. If not that, check or replace the wiring connectors that go to the alternator. This is also assuming you've tested your alternator and battery. Good luck!
