Bad capacitor or motor problem

I woke up this morning and my ac was not working properly. I went outside and noticed that the fan on the outside unit was not turning. The inside unit was on. the compressor appeared to be coming on then shutting off when the fan did not come on. I pulled the electrical cover off. There are three wires going to the fan motor. 1 brown goes to the capacotor. 1 orange goes to the capacitor. 1 black goes to the switch. I check the voltage to the 2 wires going to the capacitor when my wife turned on the unit. I have 220 to the fan. What do I check next? I pulled the fan motor out to see if it was locked up. The fan turns free. Is there a way to check this fan motor and the capacitor?
I was told to check the wires on the motor and if ther was an open circuit it was bad. I did not find an open Circuit but here are the results.
Motor Results:

BL-BR .098
BL-OR .033
Br-OR .129

I was told to check my Capacitor with an analog tester here are the results.

Capacitor Results:

I pulled out my old analog tester I went from C-F I could get it to jump to the right a couple of times then back to the left. Then I reversed the leads and got it to jum again then had to reverse them again. Now it will not it anything. It did not work each time I switched the leads just occaisonally.

What do you think now.

You did not mention how old the unit was but if it is over 7 or 8 years old I would go ahead and replace the fan motor and capacitor both at this time. If it is fairly new I might just try a capacitor to see if that would fix it.
