Bad starter? Loose hot wire from starter?

Large starter wire should be 12 all the time, small starter wire 12v only when cranking. Starter is grounded through the engine block. Maybe a fusible link is blown.

Will it start if you jump it now?

Since I can't see it from here I'm just going to throw out some things.

Check the voltage of the "new" battery and make sure it's actually charged.

Recheck the battery connections. Make sure they're clean and tight. Since this is the last thing you touched....

The anti-theft system will cause a no-crank. Try locking and unlocking the car with the key to see if you can disarm it.

Verify battery is actually good. Verify battery voltage at solenoid small post with key in crank position and battery voltage to solenoid large lug at all times. Voltage drop test cables. If all tests, good replace starter.
