6.
Check the start switch for broken contact welds or
a broken spring.
7.
Check the capacitor with an ohmmeter. A bulged
capacitor indicates failure on most motors. But
with a Centurion, the only way to verify a failed
capacitor is with the ohmmeter.
INFORMATION NEEDED FOR MOTOR REPLACEMENT
To get the right replacement motor, you’ll need impor-
tant information. Fortunately, they all can be found on
the motor nameplate. Here’s what you’ll need to know:
1.
Mounting configuration - C-Bracket, Square Flange,
or Through-bolt Mount (See page 5-7).
2.
Horsepower
3.
Service factor
4.
Voltage
5.
Pump part number, manufacturer brand name
TROUBLESHOOTING A CAPACITOR
To check a capacitor with an ohmmeter,
first TURN OFF THE POWER. If possible,
remove the capacitor from the motor.
Use an insulated screwdriver to discharge
the capacitor by shorting it across its terminals.
Then set the ohmmeter to its highest setting and attach
the ohmmeter’s clips to the capacitor’s terminals.
Check for the following indications:
1.
Needle drops to zero range and slowly rises —
capacitor is probably OK.
2.
Needle drops to zero and stays there —
capacitor most likely is shorted.
3.
Needle remains at a high value — capacitor may
have an open circuit.
