Battery Light...
 

I was out driving today and no lights on my dash were shown. However on my way back home I saw the battery light was light. I am not sure why this is light but I drought it home, shut it off. Gave it a few minutes and restarted it and the light still was lit. What could it be?

What was the voltage level at? How old is the battery? Without that info, i'd say its just a worn out battery.

take your truck to an auto parts store and have them check your alternator. also have them check your battery while your there. than you will have a better idea of where to start from.......

Its odd because when I bought the blazer they did a full tune up with a brand new battery. Its at 11.5 voltes right now.

Volts Spec:
Min: 9
Med: 14
Max: 19
Mine is using 11.5

When it's running is it still only at 11.5volts? If so, then something is amiss with your alternator. I would also recommend that you have it and your battery tested.
