Electrical problem on 93 GEO Prizm

Hi,
This has been sitting for about six months. Now that I’m ready to get some other stuff fixed to get it on the road, I’m not getting any power anywhere. Good battery, good battery connection, no power to the cockpit (no radio or door beeps). No clicking when I try to turn the engine over. How do I troubleshoot this? Thanks in advance, Brent S.
