The coil neg terminal on an inductive ign system will have ~250v, engine running. It is a meaningless reading with a DVM because you are measuring the collapsing EMF which is of exceedingly short duration, milliseconds, like the spark. Your meter was likely unable to sample such a short spike voltage. An oscilloscope would be needed to read it.
I doubt fusible links blowing is related to ign, if the ign is still working ok.
