It was quite a job to cut it open and chip away at the epoxy and fix the
connection.

There are chemicals available expressly for use in softening potting
epoxies. I gave them extensive use in un-potting electronic modules for
reverse engineering. If you proceed slowly in their application you can
soften and remove a portion of the potting without disturbing circuitry
farther from the zone of interest. Easy to use and not particularly
messy if you exercise a modicum of care.
