myers pump problem

We have a Myers submersible water pump model 3st52-5-p4 that isn't pumping any water. My husband checked the resistance reading as follows. There are 4 wires. All readings between 3 of the wires and green is infinity so there are no shorts. The other readings are black to red = 22 ohms , red to yellow = 20 ohms , black to yellow = 4.7 ohms. Do these reading look normal or are they the problem. Thanks

Author: North Carolina Plumber (NC) The start windings, yellow and red look good. The main windings, yellow and black look good. Have you checked the control box ?

Thanks for your reply
Author: joanx (ME) Thanks for your reply . Everything else seems to work but the pump. I read somewhere since posting my question that the windings should all be the same resistance within 10 % of each other. I guess I need a professional. Edited 1 times.

Re: myers pump problem
Author: joanx (ME) I had a plumper come and he said the pump is gone because there is normally no connection between the Blk and Red as they are on different windings. Can anyone confirm this.
