I don't know about you, but for me, I have to concentrate and not be distracted while learning how to use the wire tracer....and having a couple guys to supervise....not that I don't trust them mind you, I just want to be sure the job gets done right the first time.
This is beyond where Jim and I talked about the wire siganl gap.
What I was able to do is take the bundle of wires, in full sunlight, look at them closely.
[[8 strands 4 colors...2 black....2 green....2 yellow....2 red....wtf? ]]quote. was in the first post, and I was confused however...
In full sunlight, scraping the insulation deeply with my knife revealed not the above but, 1 black 1 grey 1 blue 1 green 1 yellow 1 white 1 red 1 orange.
I guess being in the ground for 25+ years took a toll on the paint pigment in the insulation.
Using white as the common, tried to get consistant ohm readings but they were all over the place.
I tried a combo of White and Blue, on the 521a and took me to a valve using White and Yellow.??
Whats up with that?
I went back and tried the combo of White and Yellow, it took me directly over a valve buried 2-1/2 that had White and Orange.
So I know that the common, is white at this leg which suggest that no one has done repairs since it was installed.
A puzzel indeed, but a very interesting puzzel.
This 521a is great tracing a wire over a long distance. I need to hone my skills locating valve and learn to trust the machine. I need get caught up on work that need to be done up to this point.
A job like this will teach you a lesson about yourself. What your weakness' are as well as your strengths.
You should practice as much as possible with your DMM before spring startups. I would say multimeter knowhow is the area most techs lack the most.
