My 67 Dino is even older than your VW with even less parasitic
stuff, the clock alone is enough to keep my charger from charging the
battery. I have one of those Red topped gel batteries from SEARS in
my car, if that is the same as your "Red top" I think the gel
batteries require a little more juice to keep charged, my charger
works fine to keep my 03 GMC fully charged yet won't keep my Dino
fully charged. Its charged enough to start the car though. What I
finally did on my Dino was buy a battery disconnect and just reset
the clock when I want to drive it (if I even bother to do that).
