Adam.....FETs arent designed to run HOT! It's a small signal device and
dosent like heat at all. So.....you might start out be replacing the
FET,
and then see where to go from there. I think that might be a cure for
your
sense problem. There are several replacement Fets that'll do the job
just
fine, so just cross reference it and get one from NTE or one of the
other
makers.
I sold all my 520 manuals, so I cant make an intelligent guess on the
voltage measurment for you...sorry.
Good Luck
