1965 Barracuda Electrical mystery

Massive gas leak down by fuel pump. Pulled alternator to get to that area. Replaced all the cracked hoses and loose clamps, put in new fuel filter. Want to turn over engine to see if leak fixed. Nada. No click, no nothing, no lights. Put battery on charger over night. Nada. Put another battery in car, Nada. Hooked alternator back up, nada. Not lights, nothing, no click.
What gives?

Thanks
Gary
