Weird reading possible fault in the ground?

Was replacing a load center at an rv park. Got tone took reading before energizing system.
Checking anything to ground and phase to phase.
I went and got 230ohms from phase be of one breaker to phase a of another. Both go in seperate pipes.
Was puzzled. So unplugged all units. Turned each breaker one at a time to see if I got any back feeding on another breaker. Non…
Plugged units in and repeated process. If I did have a phase crossed from breakers I would have saw it here. Non. Took reading to neutral bar. Everything was cool. Turned off all breakers double checked that line in question.
Now that is gone????

These are direct buried wires each 100 amp breaker feeds two sites.
Could it just have been induced voltage causeing that reading from the meter.
Using a flukexxfc forgot number.
Thought maybe a fault in the ground that go cleared maybe??? Just weird. All working now

Any thoughts
 
Did you open all of the 2-pole branch breakers to make sure you were not reading through a 240V load?
 
After that I did. But I should not have let’s say breaker 1 phase a show a low ohms reading with breaker 3 phase b. That’s why I though maybe I crossed up a wire but every pedestal showed correct voltage when I did them one at a time and the. Crossed checked the deengerized breaker load to see if it was crossed.
Did that which loads detached and then when attached since I won’t really know untile a load is applied.
 
Also, RC snubber circuits being used as protection inside of solid state devices will give you weird readings unless those devices are totally isolated from the line source.

Ya but I should still not read anything between two different breaks all together?

I don't know what you mean by two different breaks.

If you are seeing something there, it's a good bet there is something there. It might not be real obvious what it is but there is something there. Otherwise it would read open.
 
Panel has 10 breakers
Each feed two sites

breaker 1 and breaker 5 has the reading between phase a on breaker 1 and phase b on breaker 5.

I turned each of the 10 breaker 1 at a time and checked to make sure none were back feeding any other breakers
Also went to each pedestal to verify voltage. Everything was fine.

As soon as I energized the reading went away.
