Carl,
I realize this came from a manual but unless I'm reading this wrong, this is
the same condition as when the steering column switch is on. The contacts
are just electrically stuck. This provides potential but until one of the
isolator switches is closed there is no path to ground, therefore no current
flow through the solenoid, therefore no engaged solenoid. As the manual
section reads to me, you'd have OD in all gears whenever you turned the
switch on.
