67 C20 no electrical power - help!

[Bones69]

I picked up a 1967 C20 a few months ago with 68700 original miles one owner. I am proud to be the second owner of this old work horse! It has been used but always in a shed and has zero rust! I replaced the points distributor with an HEI about a month ago. Ran great till the other morning. I turned the key and turned the engine over a half revolution and I stopped because I had forgotten to turn the choke on. When I went to turn the key again there was no power to anything. I am assuming it has something to do with the voltage regulator but I am not sure. I did a little trouble shooting but I am not sure what it is yet. That is why I am checking with you guys. What do you guys think it is? I will have to post some pics of the old green bean soon.....
