HELP!!!!! my battery isnt charging. i know the battery is good because i have charged it several times and it holds a charg for long periods of time. after about 5 days the battery is dead again. i know the alternator was bad so i replaced it along with the voltage regulator. i was wondering if it could be the starter solenoid??????? just two days ago with the truck running i put a multimeter to the battery and it had a good charge. when i pressed on the gas it read that it was getting more juice as engine speed increased. any help would be appreciated.

Take the battery out of the truck & tote it to your local Advance A/P (or like kind parts chain store) & have it tested.
When the alternator last crapped out on my '78, it fried a 2 month old battery (got shorted). The battery may register it taking a charged at the correct voltage while running, but that does not mean it's holding the charge that will be needed when you go to start the truck.
