I have a motor with five wires as shown in the pictures, does anyone know how this should be wired with a start and run capacitor set up.

 

Any model number on the motor, I would think the Black and Grey wires are the capacitor, the other 3 will be the two windings, you can check it out with a multimeter.

The grey wires were tied together, the black wire has a connector that goes to one of the capacitors, what values should I be looking for on the meter?

 

Put the meter on Ohms and measure the resistance between the Blue, Yellow and Grey,

What is the resistance between the Grey and Black.

The resistance figures are

Blue / Yellow 2.2
Blue / Grey 3.9
Grey / Grey 1.5
Grey / Yellow 3.2
Grey / Black 3.7 Grey Black
Grey / Black 3.7 Blue Yellow grey

Did you get my message showing the resistance readings?

See what @MaxHeadRoom thinks.

 

Okay thanks, how do I contact him?

 

As per post #2, is there any info or data on the motor plate??

Doesn't seem to be a data plate but the updated SIP compressor uses this motor. https://siptoolshop.co.uk/products/06559-air-compressor-motor-230v-13amp-3hp-mec-90

Don't know if this diagram helps any

So I take it this has everyone baffled, is it time to buy another motor?

 

Can you put some tape of a different color on one of the grey wires. (So we know which one we are talking about.)
Touch your meter probes together and tell us what reading you get. (This is so we can subtract the resistance of the test leads from the readings that you get.)
Repeat the reading in post #5 indicating which grey wire has the marker on it.
This should give us a better idea of how the windings are connected.

Been absent !
So what is wrong with the diag in #12. ? What is not understood?
R & C appear as the run winding and should have the lowest resistance.

I didn't know if it was the correct wiring for that motor, will that work?

That is a typical connection.

Thanks, I didn't want to melt the motor.

 

What we CAN see from the diagram is that the blue wire is one end of the run winding.
What id missing are the values or the two capacitors, start and Run, as well as the rating of the current operated start relay. So the TS needs to contact the motor manufacturer for the missing information.
IF somebody has away to magnify the screen display that shows the motor along with the name-tag, it may be possible to see the actual motor model number.
It will certainly require both capacitors and the relay, as well as a suitable enclosure.
And certainly whoever clipped the leads so very short needs to be educated as to the correct way. At 330 pounds this is not a cheap motor.
