Default Electrical issues

This is my first and honostly probably my only 1986 c4 corvette, I really love this car and bought it like this, Runs strong and drives very good,But if I leave the battery hooked up it will go dead by morning ,the batt. is new so it not that, also the radio clock works and can hear humming throuh speakers,but no music or station tuning, also everytime I hook the batt. up and start it the A/C turns on,Is that because the batt.is disconnected?,Any help would be greatly appreciated,let me know please

Correct , the A/c resets and needs to be turn off manually.
You have a battery drain somewhere.
Can only be found by use of a DVM

Also, the radio needs 2 fuses to work, CLK/CTSY and Radio, test them both.
