I am trying to establish if wire is back or good. I dont get continuity when i read between white green and black wires but if I set meter on ohms I do get and ohms reading between the wires despite not being connected at either end.
 
It doesn't even need to be in the megaohms range, a reading as low as 75 Ohms may not register as a continuous circuit depending on the meter. Are you measuring across a potential load?

what kind of ohms reading are you getting? if it is multiple megohms that basically is an open circuis

sorry for late responses and I wrote this post in a hurry. I would still like to get help with this question. I am using a simple voltage meter with ohms/continunity setting. I have a green white and black wire open at both ends. I put meter on continuty and I connect wires at one end I get continunity between wires. if I put meter on ohms setting and I leave wires open at one end and put meter on wires at other end I get ohms reading without any wires touhing. I am getting ohms reading without any wires touching. Is normal to get ohms reading through wire without it touching anything?

what is the reading and what conditions are you in ( inside dry, outside wet, underground, etc
)
 
And how are you connecting the probes? If you’re holding them against the wires with your bare hands, you will likely get a reading through your body depending on the meter type and range setting.

Check for voltage between the conductors. If the conductors are running close to conductors with voltage on them, there can be enough coupling to put a small voltage on conductors that are open at both ends. The voltage will cause an ohm meter to show resistance.
 
I would also caution against reading too much into a continuity beep. All that means if the resistance was low enough for the meter to decide there is continuity. When you are scratching your head what's happening, you need to be on resistance and not continuity.

I agree.
 
If you are holding the leads with your hands and they are touching the wires then you will read resistance thru your body

You still didn't state what the reading was when the ends were free
