Wire the red and black to the Line 1 connection on the motore, and the blue on the Line 2, Make sure your motor voltage is correct and turn on.

Yes this is an old thread but info is still helpful to those that are searching. Here is one diagram from a 3/4 motor. Be aware that most residential high voltage are 240v. This will have the motor turning a bit faster.

I'm making over €7k a month working part time. I kept hearing other people tell me how much money they can make online so I decided to look into it. Well, it was all true and has totally changed my life. This is where i started... w­w­w­.­S­n­a­g­4­.­c­o­m

The values are stamped on the old capacitors. If you haven't got them, I would contact the manufacturers authorised agent for advice.

the capacitor is located in the housing that is on the top of the motor.

remove bump on motor and take picture of wiring before removing get numbers off try electrical supply

Thank you for posting your question here on Fixya.com.

White is common, Black high speed, blue medium speed, red low speed; Brown wires are for the capacitor; The remaining 4 are for selecting the rotation.

For details look at the AOSmith print here.

Try priming it water at the filter. Make sure that the filter o ring is sealing under the cap. Make sure there is enough water in the pool to enter the suction line and that it is not restricted.

To get to the Impeller you need to remove a series of bolts, or a large clamp, that holds the two halves of the pump together. Once you do that, if their is a diffuser (housing that goes over the impeller), remove it. To remove the impeller, you need to lock the motor shaft. You can do this a couple different ways depending on the motor. There will either be a small cap that grants access to the motor shaft on the back of the motor, or you remove a larger housing that grants access to the wiring and other components in the back of the motor. If it's the small cap, then you can hold the shaft with a wrench. If it's the larger housing, then you can slip a wrench (probably 7/16") under the thermal overload switch and onto the shaft to lock it in place. Now you can unscrew the impeller. Check to see if the impeller has a screw in the center. If so remove this first. It will be reverse thread. The impeller should spin off counter clockwise. If the impeller is very tight, be careful not to damage it. If you don't have an impeller wrench, I strap wrench, or very large locking pliers with a rag around the impeller works well. Hope this helps. If you need further assistance post a reply in the comments, and don't hesitate to leave a good thumb rating if you found this helpful. Thanks, and good Luck!

The type of motor that uses a centrifugal switch, a brushless induction motor is considered too large and heavy for a portable vacuum cleaner though they are often found in permanent installations. Portable vacuum cleaners use a series wound motor that is considerably smaller and lighter for a given power output and turns many times faster. Both types of motor will hum if seized or locked and in that condition the series wound motor will soon destroy itself. It takes a little longer for the induction motor to overheat... The centrifugal switch is not fitted to all induction motors and that is usually very reliable and rarely gives trouble except when unused for a long time in damp conditions. Many single phase induction motors with or without the switch use a starting capacitor and sometimes a start/run capacitor. Often the capacitor is of inferior quality and will fail with the result the motor will just hum, though will start when the shaft is spun by hand.

Can't do it electrically. See if you can flip the armature and use that in that direction [bit of a long shot here - sorry]
