Which battery did you replace? The "main" battery is the one closest to the windshield, the other battery is the secondary battery. Checking the grounds is a good start, dont forget to clean the connections on the battery too. If that doesnt solve it it could be a bad alternator. A simple way of testing it is to start the truck and touch a wrench or srewdriver to the alternator. The alternator is like a magnet, the wrench or screwdriver should stick on it like they would on a magnet .
