I was having the same issues, after replacing my battery, alt, and starter I finally changed my battery wires and it fixed the problem.
The old wires were all corroded and I think they were wet inside the shrink wrap.

Have you looked at your starter? Could be possible that it's went out as well, that could cause it to not crank.

Assume nothing. Verify everything.
Disconnect both battery cables. Test battery for proper voltage. A fully charged battery will have about 13V. It is possible your battery store has a bad lot of batteries. Not very likely but possible.

Once you know the battery has proper charge, check the cables. If they look like they are a couple of decades old, just replace both. As Telecasterjoey said, they can look ok on the outside and be rotted on the inside.
If the cables pass the eye check, clean the battery ends of both. Then start with the ground cable, and loosen and re-tighten the engine ends of both cables. While you are down at the starter, check the other connections and cables on the solenoid. Disconnect the ground cable while checking the solenoid/starter cables to avoid risk of loud noise and green fire.

thanks for the guidance also I forgot to mention when I got the first battery I got new wires as well

Check to see you have power at the starter terminal. It should be identical to battery voltage. That will tell you if your starter is bad or not.

Mine did something similar, I put on a new starter and new battery terminals and I havent had a problem since.

thanks guys turns out it was a broken wire on the solenoid thanks for everything guys. now we're off on another journey wiring! the joys of having the freedom of a vehicle

"The joys of having the freedom of owning a vehicle."

I get the tongue in cheek comment, and agree, but there is tremendous freedom in being able to fix a vehicle. It's hard to even find the battery on many new cars today, let alone replace the wires, and solenoids.

Good job!
