How to wire a marathon motor? - Hayward 2HP Pool Pump Motor A O Smith Electric Pool Motor for 56J Frame

You should have a wiring diagram on the motor, if not you should be able to google (marathon motor wiring diagrams) and find your model number or go to marathon motors website.

Are you sure? Single phase pool motors are not reversible (unless something weird happened that I can't explain). Three phase motors are reversible, but very rare in residential wiring.

Looking directly at the end of the motor shaft (where the impeller goes) it should spin counter- clockwise. Both of the power wires can be attached to either terminal; there is no "polarity".

what are the colors of the wires on the new motor

check for 230v not 110 (on line to ground). SO checking L1 and L2 should show 230 v if not you have a fault in the timer or the breaker is toast. depending on the timer you can clean the points

HAVE POWER TURNED OFF AND LOCKED OUT. If the motor is a dual voltage motor it should have a wiring diagram on the motor. Check on the name plate of the motor. You should see a high and low voltage diagram. Follow the low voltage numbering. The widings need reconfigured to operate at a different voltage. Hope this helps you...Jim

Wiring diagrams for AO Smith motors are located on the side of the motor.
