   You need to have a good understanding of electrical circuit to make any sense of a amp probe or TDR..

   Amp probe will only work if the circuit is active. TDR will check the path with no power.

   The gentleman with the amp probe knows how to read the results. He found a high amp reading (load) and searched from there.

   Good luck!

   TNX for the recall notice. (Where do you find those?)

   Nope, don't have one of those.  My clamp meter is a lesser one from the depot.  The ToolBear

   I've had real good luck with this one:

   The version with the clamp-on tone injector is worth it if you do any work with either direct-bury wire, or with metallic conduit, buried or not.

   The version with the clamp-on tone injector is worth it if you do any work with either direct-bury wire, or with metallic conduit, buried or not.

   Have done both.  Had 91 acres of area lights all done in alum. UFer.  Never lacked for work <g>.  This project has 65 light pole redone in '89 in rigid and/or P40.  Mostly in pipe.  Wire is CU, solid or stranded and any color they had on the truck.  White hooked to green, green to red, etc.

   I broke down over the weekend and snatched at a new AT 4004 on ebay.  Hope it gets here in time to figure out why a sector of garages have no lights.  Hope I can hook it to a cast iron drain line on the next project and lay out where the plumbing runs.  Anyone tried that?  And what about that short on G4/B3?  No outage reports.  Have to trace that conduit.

   We are down to the last two poles tomorrow.  This has bee a very interesting project.  Whoever did it last was not a slave to convention.  Green = ground?  Some times.  Also blue, etc.  One hot left the box in black and arrived at a light as a yellow.  You could not trust the context one bit.  The ToolBear

   bear,

   Yow, you seem to get the "interesting" projects, meaning the FUBAR ones.

   How'd you (or the company) handle the fee on this one?  With all the variables, did you bid it assuming as a worst case--after some troubleshooting and tracing, that you'd have to lay all new pipe and pull new wire, or did you bid it T&M?  If the latter, did the client want a cap and if so, how'd you respond?

   Lastly, how is it looking on the job costing--i.e., projected cost vs actual?  Lose your shirt, or make a pile o'dough, breakeven, or what?

   There are a half-dozen different technologies used for wire tracing and fault identification. The specific technology that's best depends on the application. Eg, some schemes can be used only with AC wiring, some work with wires, pipe, conduit. TDR will tell you how far away a fault is, but won't help you locate it behind a wall or underground.

   So convenient a thing it is to be a reasonable Creature, since it enables one to find or make a Reason for everything one has a mind to do. --Benjamin Franklin

   The boss sprang for a starter version from Walter's Electric and it found the conduits today.  Nothing fancy.  Swing the "antenna on a string" and look for the nulls.  I chant "Dies Irae" in Latin as I go. 

   Dug at the null line where the signal began to fade, and there was the conduit.  There were two conduits.  How did they wire this sector?  We suspect an underground pull box.
