Bad caps.
Bad starter.
Bad wire.
No Freon.

Don't be in a hurry to condemn the cpmpressor.

You should be able to find the spec for locked rotor amperage. Put an ammeter on it and see how much it's drawing. If those two numbers match, it's toast.

Have put in new caps
What does the starter look like Is it the black cube with 5 terminls

If it wasn't the start/run capacitor, the compressor has probably seized. Unfortunately, I've seen that in marine, residential, and mobile AC and refrigeration systems.

Did you make sure to get the polarity right on the capacitor? You might be able to add a hard start capacitor to buy some time
