the voltage gage on my 91 f250 5L read quite low when i started the engine yesterday. the defrost lacked power, so i think the gage is reading correctly. i have driven the truck for about 45 minutes since the gage started reading low, and other than the weak defrost, it has run fine. the battey is less than a year old. what could cause this problem? i am aftraid if i dont attend to it soon, i will lose all electrical power.

First thing i would do is check and see what is actually charging at and go from there
