Short circuit in 12/2 wire

I have a dead short in a 12/2 romex cable buried under ground. I have been able to isolate the affected cable. Can I measure the resistance in the wire to calculate where the short is. What I mean is once I measure the resistance can I measure off in feet to where the short is.

I have moved your post to its own thread. You had posted to someone else's thread and that can cause confusion.

No, a resistance reading won't help. Is this UF cable or NM-b (Romex) cable?

No, but why do you want to know that? Don't you just need to replace the full run?

If this is UF cable an underground splice kit can be used. If it is NM cable the entire run needs to be replaced.

You can't measure it with a multimeter but this could be done with a time domain reflectometer. Some electricians may have one. It will find the break. If this is a short run I'd just replace it.
