MY 95 blazer runs fine yesterday night. And I parked it outside my house. It lost all power today when I want to drive it. No lighgt can be turn on , of course it can not be started, even the keyless entty system. What happened? I checked the electrode of power supply, it was fasted very tight. HElP! Thank you very much.

 

you left your interior light on and killed battery.
