I agree, Rob - since part swapping is usually a quick way to verify if a part is operating correctly. I would also have been tempted to call the cable good and look further for a different problem. I have done it in the past (just grabbing another part out of a parts bin) and after wasting time verifying everything else was okay, I would return to the part I had called "good" and finally figure out that while it was not the obvious answer, the replacement was also bad. Glenn did a great job going to a KNOWN good cable to make his call - a great tip for anyone involved in troubleshooting!

Good point Naperlou. Glenn will likely weigh in on this. If the cable was new but defective, you would get a powerful bias that the cable wasn't the problem.

Glenn, that was good work.  I always found that there are often several different failure modes and it is important to isolate them.  The problem with the second cable is a difficult one.  I wonder if that cable was considered "new" or if it was a spare from another unit.

Good detective work, Glenn. When the replacement cable was also bad, it would have been easy to determine that the cable wasn't the problem.
