If you are going from 13.8 to 12.0v on SSB, you are warbling.
Make sure you are using DC fuses (32v) rated at least 20a. Even if you are, swap them out for new ones. I have seen fuses not blow but under current, develop high resistance on one end. Make sure you are using the original power cord or heavier.
