Howard,
A technique I use is to make up some short pairs of wires with D-subminiature
pins like in the first attached image. The wires can be used to "bridge" a
D-subminiature connector pair and at the same time allow connecting a test lead.

This technique gets old fast if the mating pair contains more than about four
wires.  In that case, I use a fixture similar to the ones shown in the
second image (but with more connectors).

The ribbon cable can have any reasonable number of D-sub connectors attached
(they are easily crimped in a small vise). My favorite is to crimp on 5
connectors: a male and a female at each end and an additional connector for
probing. This makes a universal breakout fixture and can also function as a
temporary gender changer.

Folks,
Just wanted to say THANKS! for all the great ideas on how to accomplish this data breakout. I was able to craft my test rig, and determine my RPM issue.
Much appreciated! I love the AeroElectrics Forum!!! What a great resource for us experimental folks.
Sincerely,
Howard
