Nice pics, Emerson hates to give info over the web.
This is too risky to just guess. I have some ideas but I don't feel right putting them out there.


They will probably help you.

You toook good pictures but not of the right stuff.

Please post a viewable picture of the wiring diagram on the bottom half of that nameplate even if it is hard to read.
Also it looks like someone may have taken the capacitor off this motor... do you know if this ture?

If that isn't a wiring diagram on the bottom of the nameplate look on the inside of the wiring cover you took for lyour pictures of the wire terminations and see if there is a diagram there. Take picture and post it.

The problem was that the wiring on the tag of the motor was unreadable and there was no diagram inside the cover.
So far I have tried numerous times to get in contact with Emerson, without any success, but got a good technician at Campbell Hausfeld. He has send me pictures on how to change the wiring from 120V to 220V. So I changed the wires and installed new capacitors as they were bad. [I took the pict with the capacitors removed] <o></o>
When I started the compressor the motor was working, but it was as if the running capactor was failing I guess. It reminded me at the sound of a 4 cylinder car where one cylinder was not fired.<o></o>
It took half a minute and then the smaller capacitor [i suppose the running capacitor] blew up.<o></o>
So now I have to tackle that.<o></o>
Do you have any experience with this?

In the past I runned the compressor in different places on 120V but lots of times it blew up fuses as the breakers were just not enough to restart the compressor after some time. When the motor stopped working I decided to have it wired for 220V and bought new capacitors at Grainger [both running and starting] .
