Glen, That warning light may give us part of the answer. If it's a pressure
sensitive switch mounted on the master cyl then it knows nothing of the
status of the accumulator, right? I know you're not fond of parts swapping,
but I've got that '80 5000T master cyl handy....four lines and two bolts and
you've got your answer. I don't have a spare accumulator handy though. Might
be able to arrange delivery/assist if you'd like.
