1 PHASE PUMPS
1. Use an amprobe to check the amperage of the
pump.
2. Turn the hand-off-auto switch to the "HAND"
position and compare the amperage reading to
the values shown on the chart. (See page 9).
3. If you get a reading of 0, make sure there
is voltage to the motor leads. Push the Klixon
overload reset button in the control panel. the on
winding overload may be tripped. Wait 15 minutes
and try again. If you still do not get a reading,
either the motor has failed or there might be a
wiring problem between the control panel and
pump (improper connection in the junction box).
3 PHASE PUMPS
1. Use an amprobe to check the amperage of any of
the power leads going to the pump.
2. Turn the hand-off-auto switch to the "HAND"
position and compare the amperage reading to
the values shown on the chart.

3. If you get a reading of 0, make sure there is
voltage to the motor leads. Push the overload
reset button on the overload relay in the control
panel. If you still do not get a reading either the
motor has failed or there might be a wiring
problem between the control panel and pump
(improper connection in the junction box).
4. If you get high amperage readings on 2 wires and
a zero reading on the third, you have a single
phase condition which could be caused by one
of the following:
A. One motor lead is not connected properly.
B. You have lost 1 phase of the 3 phase power
coming into the panel.
C. One winding in the motor is open.
