2000 Chevy: the truck started to lose volts slowly while I..tight

Customer Question

I have a 2000 Chevy S-10. My battery light came on and the truck started to lose volts slowly while I was going home. My battery cables are tight. I do have electrolyte in the battery. Last time this happened I had to change out the battery. Now it does it again. Could it be the alternator?
