What did I do and how do I fix it? 1953 Mercury

[engine103]

Started off trying to solve a right turn signal problem. All running or parking lights worked but no turn signal on the right. Sequence as follows:

1. appears prior owner replaced lamp socket with new but did a bad job splicing wiring so unwrap electrical tape and yes very bad splicing.
2. connected one wire and bulb in fixture and it lit up and also produced a weak blinking both front and rear.
3. connected second wire to socket (see wire in picture) bulb went out.
4. EVERYTHING WENT OUT! No lights no starter no nothing! a complete electrical shut down! Checked the only two fuses I know under the dash and they are good. My battery is a trusted battery and appears good.
What did I do? The good thing, there was no smoke anywhere.

That is not MY wiring in the photo.
