Security Light stays on

I have a 2001 silverado and the security light is always on. While driving the security light, batt light, low fuel light come on and the gas gauge does not work, the abs light is on, no gear indicator, no hi beam indicator light, and the temp gauge does not work. The truck drives fine it is just it runs the battery down overnight. Thanks for any help in this matter.

Have battery and cabels tested and alt for proper charge.
Check the truck off amp draw and find out if it has a short.
