Default 69 wont start

Hello everyone, I started my 69 a few days ago and all was fine. Today I did a vacuum hose replacement on almost all of the hoses and went to do a vacuum leak check and now the car acts like the battery is dead. I did manage to get it started and when I went to test the head light I pulled the switch and the car died and wouldn’t start again. Not even a click for the starter. For informational purposes the vacuum tank was bypassed and now it is not. That is literally the only thing different. Not sure if these two things are related or just a fluke that something shorted when I changed the hoses and now I have two separate issues. I am new to this car and it has been sitting for about 10 years or so. Anything is possible. Any insight would be great. This is my first corvette so I am learning a ton here, thanks to everyone.

Welcome to the forum.

When you say you “managed to get it started again”, what exactly did you do to get it started?

Any idea how old the battery is?

Even if the battery is low. Once running it should stay running electricly anyway, on the alternator output. You turned on the headlights and it died.
This is telling me your not getting any output from the alternator. Did you accidentally knock a wire off?
get your battery on a charger. Keep the charger hooked up and get the car going again. Then test your charging system.

I will check the wires. I will check the output of the alternator. Thank you.

Once you get the battery charged, check to see if there is a parasitic drain. You’ll need a multimeter to do that.

Check the snugness of the alternator and the horn relay connections - you may have knocked slightly loose wire to a fully loose wire when routing the vacuum hoses.
