Not quite sure what you are saying, here. The idle current is supposed
to be reduced, but certainly not to zero. If the circuit that turns off
the
reactor bias fails, then the reactor gets bias current all the time and
the
drive runs at full voltage all the time, either burning up the motor or
frying transistors. The reactor bias circuit was what I was trying to
help somebody debug through the net.
