Yeah there hasn't been too much to comment on LS lately.

However. I did learn the other day that with a nicked wire and the zone showing 600k ohms I could still locate the valve with the positive on the zone wire and ground on the common.

Yea, and it shouldn't be a problem locating all the other valves on that common.

So? Don't brag about anything unless you tell us what device was used to measure the ohms and the other to find the valve. Hard to believe 600k ohms, but my old trusty Fluke 77 with auto ranging may have adjusted for it.

Tools : Remote, Greenlee multimeter, Wire stripper, Station master, 521 locator.
Needed: Fault locator and that TDR would have been handy too!!

hmmm- it was the last thing I tried lol. A new water feature install nicked the wire run . I needed my fault locator but I needed to find the dang valve too.

Zone 11 wasn't working ( 11 zones) > Greenlee multimeter showed 600k ohms.( Broken wire or nicked wire) > Walked around the area of the zone looking for a VB > Located 1 vb of 2 valves but they were not it> Wiring was absolute mess> Traced out zone wire only from controller all the way to this valve box. > Hooked up remote and tested in VB- No useful readings leading into this vb > Disconnected common and zone wire- Traced backwords/ flagged Both wires individually and traced directly back to the controller . > Quickly located a total of 13 valves ( 2 extras wired in the field as well Except my bad zone of course) That were all buried a few inches> Used process of elimination to find vicinity of valve.

Thought hmmm where the ef is this valve. > Attempted to common and zone wire trace and followed flagged line> Found it. . Obviously this wouldn't have worked for a broken wire, but then again I wouldn't have been able to trace the line out to the next VB.

The wire follows DIRECTLY UP THE MIDDLE of a 15' new water feature that a joe smo installed.

Used the one spare available wire and then recommended a wire reroute around the feature..

Total time 1.5H

How come? It just means a broken wire / nicked wire grounding out. It took 600k ohms to return the path back to me which means earth ground was my path of return.

Using short to earth measurements again Mitch, good man.

the fault wasn't too severe was it?

Well done, Mitch, just checking. As I recall, resistance below 700k would indicate a nicked wire making contact with earth.
