Hello there, a few common failures can prevent your 1984 Volkswagen Rabbit from charging even after the battery and alternator have been replaced. The most common would be the battery cable, a faulty voltage regulator, a bad alternator fuse, or a wiring harness fault. If you need to have the problem scoped out further, a certified technician, such as one from YourMechanic, will be able to diagnose the charging system to that this can be resolved accordingly.
