Hmmm...are you sure it's busted?  I have an '84 with electrodes in the side
of the tank, so I haven't seen your setup -- but on mine the yellow light
means everything except "almost full" and "almost empty."  Says so right in
the book, and that's how it works, too.  Green means (roughly) > 11 gals,
Yellow > 2 gals, Red > 1/2 gal, No light < 1/2 gal.  If yours is like that,
I bet it's just fine.
