That would be my guess too. Inspect the wire and other side terminal, and if you have the slack, cut off an inch and crimp a new terminal, also check the connector, as it may also have been compromised, and it will most likely require a few passes with emery cloth to reveal bare metal, or maybe more, while you are in there check all the connectors. I gotta do the sequencers on my air handler before the heating season, same idea, more voltage...
