522760-4 Switched Battery Voltage 1 (IGN 1) OORL
is the battery charging correctly while running and are the grounds and battery cables clean?
did someone try and use this machine to jump start some other machine?
if it was me, first make sure no one has added ANY devices (bac-a-larm? scanner? scale?)
if no, then replace the relays in the power distribution box.
