CAUTION should be
exercised when
testing any of the
control wires. Use only a
quality volt meter. Do not
ground or spark wires. This
will permanently damage
the motor control module.

Please refer to Section "1 B" for bleeding procedures.

Motor Solenoid

1. The pump motor solenoid is located on the side of the motor at the pump manifold
assembly. This solenoid controls the electrical power to the pump motor. The solenoid
has four terminals, two large and two small. The two large terminals are for the
connection of the battery power cables; one to the pump motor and one from the vehicle
battery. The two small terminals are for the connection of the control circuits; one for
ground and one for power (Figure 4a.)
when a leg button on the control panel is pressed and the pump motor does not operate,
replacement of the pump motor will be necessary (Figure 4a.)
4. If no voltage is detected at the solenoid to motor connection check the solenoid
power wire from the control module. Note: Caution should be exercised when
testing any of the control wires, use only a quality volt meter. Do not ground or
spark wires. This will permanently damage the motor control module. When the
control panel leg buttons are activated power should be detected at the wire that is
connected to one of the small terminals on the motor solenoid. If power is detected and
the solenoid does not operate replace the solenoid (Figure 4a.)
5. When no voltage is detected at the solenoid control terminal the control module will
require replacement. Refer to Segment 6: Control.
2. Pump motor will not operate. Check
battery voltage and connections,
voltage at the battery to solenoid cable
connection should be approximately
12.6 volts. Reference Segment 3:
Electrical, for battery and connection
information.
3. Check motor solenoid operation.
Solenoid should engage each time that
a leg button on the control panel is
activated. Using a volt meter check for
voltage at the solenoid to motor
connection. If voltage is detected when
a leg button on the control panel is
pressed, this indicates that the motor
solenoid is operating correctly, If
voltage is present at this connection
