MOTOR TROUBLESHOOTING

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.
