10. If fluid does not start draining, does not keep draining or does not stop draining:
a. Disconnect power source from fuel/water separator control box (22).
b. Disconnect harness (29) from solenoid drain valve (28).
c. Place red multimeter in socket A of harness (29) and black lead to ground. Reconnect power source to fuel/
water separator control box (22). Check for voltage.
d. If voltage returns to zero within 15--seconds, replace solenoid drain valve (28) (WP 0219 00). If voltage does
