OK..  The next step involves some technical skill.  There are several
glass fuses (very small on the "newer version" 2500 boards but a more
standard "AGC" size on the older ones).  Power down the system and meter
the fuses.  Replace any that show "open".  I'm guessing your aux power
supply fuse is blown.
