Toward the bottom of the schematic, column G, notice the 1/2A fuses for each of the control bank resets, the main one and the Yellow and Green. Check that those fuses are all good. You'll also need to locate and check all of those associated Armature switches.

Generally a good idea, and while you're doing it make sure the fuse holders themselves look good, with plenty of spring tension on the clips. If not, replace those too or they'll cause you no end of trouble.
