The battery disconnect solenoids are easily opened and the contacts cleaned. Assuming you have the top hat type solenoids in your BCC.

I found this out also when I replaced both solenoids with new ones. I took the old ones apart and cleaned the contacts with a nail file. You could see where they were burned from arcing. So now I have two spares. Both of mine went within a year of each other at 15 and 16 years old, so replacing/cleaning old ones are good preventive maintenance.
