Water Pump
1. Test using the controller’s indicator lights. Check the indicator light during the freeze cycle.
The light will be On for all but the 30 second anti-slush period, so observe the light for one
minute. When it is On, check the water pump, it should be operating. If not, check voltage to
the pump. If low check the voltage from the controller to ground. The water pump pin is
number 6. If there is voltage at that pin to ground, but very low voltage at the pump motor,
there must be a broken wire in the harness. If the voltage is low at pin 6, the controller should
be replaced.
2. Test using an ohmmeter. Disconnect electrical power. Unplug the water pump motor leads
from the harness. Measure the resistance of the motor windings. If open, replace the pump.
Measure resistance to ground. If there is any, replace the pump.
