Chevy Silverado 2004 8.1 gas engine. Ran well until battery went dead as I left something on in the cab, recharged both batteries and they are staying charged, truck starts right up, but only stays running for 3-5 seconds then shuts off. Checked out alternator working good, high output. Noticed that the charging guage does not advance up however on the dash. Needle moves, but does not go up to 12 or 14v. Don't know what to check next?

There is a fusible llink that runs off the generator that may be bad. There also is afuse holder near the right battery and a auxillary relay at right rear of eng compartment. Put a volt gauge on your battery and see how may volts it gets while running at about 1500 rpm. Also with 8.1L they tend to loosen the intake bolts so see if they will tighten. But don't be a gorilla as they will break they aren't that big.
