jayfire Posted March 21, 2012 Report Share Posted March 21, 2012 My problem I am having with my Marquis spa is that my old motor was blowing a fuse every month, but was still working properly. I bought a new GE Marathon motor from the Spa Depot (3HP 230 volt, 10/2.9 amps, 2 speed) and it will cycle on/off non stop on low speed only, but works fine on high speed. This is with the wet end attached and with a load of water on it. When it has no load (water), it will run fine in both speeds. I called Spa Depot and they sent me a replacement motor, no questions asked, just had to send them the sticker off the other one. I got the new one in, installed it, and it is doing the EXACT same thing! I reinstalled the wet end on my old motor and installed it, and works just fine in low and high speed. My dilemma with the old motor is it has two different stickers on it with two different model numbers, so I do not know which one is the right one. (The spa is wired 220 volt). First sticker reads: Ultima 230 volt, 11.9/3.3 amps, 2 speed, and the sticker next to that one says: Ultra Jet by Vico 115 volt, 11.9/3.9 amps, 2 speed. Both have different model numbers. Anyone have a direction I should look? Spa Depot claims I did not receive two bad motors. Anyone think maybe the new motor could be a little too small?? Please help.

n1oty Posted March 22, 2012 Report Share Posted March 22, 2012 What voltage does the pack put out to the motor on each speed?? John Quote Link to comment Share on other sites More sharing options...
jayfire Posted March 27, 2012 Author Report Share Posted March 27, 2012 What voltage does the pack put out to the motor on each speed?? John This is what I got for voltages on the new motor. (White=Common, Red=High Speed, Black=Low Speed, Green=Ground). Low Speed-No Load-- W-R=85 volts W-B=120 volts W-G=85 volts B-R=120 volts Low Speed-With Load--W-R=5 volts W-B=120 volts W-G=220 volts on and off High Speed-No Load--W-R=120 volts W-B= All over the place W-G=220 volts B-R=120 volts High Speed-With Load-W-R=120 volts W-B=5 volts W-G=5 volts Anyone have any input on the results I got from this?

ChaiSTi Posted March 28, 2012 Report Share Posted March 28, 2012 This is how it should look w/load: Low speed W-B: 220V W-R: 0V High Speed W-B: 0V W-R: 220V you shouldn't have any voltage between neutral & ground. you're either missed wired these pumps, have bad pump cords, or your circuit board is no good.

Dr. Spa Posted March 28, 2012 Report Share Posted March 28, 2012 This is how it should look w/load: Low speed W-B: 220V W-R: 0V High Speed W-B: 0V W-R: 220V If you disconnect the wires from the motor and test, this would be correct. However, if the wires are still connected to the motor, voltage will typically back feed through the motors windings and give you a 220v reading where 0V is listed above.
