I have a 1980 Ford f-150 5.8 liter, and the main problem is the alternator is not charging the battery, we have replaced the alternator and still nothing, we replaced they battery and the new battery is dead after 3 weeks, we changed the voltage regulator and it charged for about a week and then it went back to discharging, we replaced the starter solenoid and still nothing. What could be the problem of the truck not charging?

It sounds like the regulator may have gone bad again. When you replcaed it, it worked. Have you tried another regulator?
