Sounds like you have an alternator problem to me.

PMD and grounds.

SSdiesel is worthless. Remount the PMD behind the front bumper using one of the license plate bolts and order the PMD and Extension cable from an honest business man like Leroy @ LEROYDIESEL.COM. If your pmd is free reving the engine then it is already toast.

While you wait check and clean all of the grounds. If you have a ground issue the look at thetruckstop.us, they have the best GM crowd around IMHO. These trucks are very ground sensitive.

When you say you're truck wasn't charging what led you to that conclusion?

try this, get the truck running and turn on your high beams/ air conditioning/ radio/ and anything you can, then check the battery voltage with the engine running, see what the alternator is putting out voltage wise, turning on everything puts amperage load on the alternator and with out the equipment to test what the alternator is putting out amperage wise this is a easy way to see if the alternator is putting out proper amperage as well as voltage, if it wont stay running you might have a bad alternator, remember just because an alternator can put out 13 to 15 volts doesnt mean its producing enough amperage to run the vehicle, try to remember the batteries only purpose is to start the engine, if it keeps dieing then something else is wrong
