I must have the left the pack on and it looks like there is some corrosion in in the body pack. Any ideas of how to make it work again?
Relay G50 Battery Corrosion

It'll definitely need a "clean-up" before you try applying volts again, Randall...
But if the "mess" is really bad, the internal damage may well have proven fatal, requiring a whole new TBP12 beltpack.
Start with the contact strip on the "swing door".
Initially, it is normally relatively easily attended to by gentle abrasion with a pot-scourer dipped in (of all things) milk.
(Milk is just acidic enough to gently neutralise the white alkaline gunk that we're trying to remove ...and at this point it's worth noting that with any such abrasive cleaning of corrosive residue, "gentler and longer" is always better than "harder and faster".)
Once we can no longer see any "gunk", it's often best to burnish the contact areas with a tiny dab of toothpaste on an old toothbrush, followed by a scrupulous "washing down" with cotton applicators that carry a tiny amount of a kerosene-based "WD"-type contact cleaner, followed by a really careful "towelling off" to complete the treatment.
The really hard bit is then to repeat all of those steps with implements similar to the above electrical-taped (or otherwise fixed) to the end of a screwdriver or whatever handled implement that you find grants you access to the battery compartment's internal "spring" contacts.
