A thought process I've tried to inject into many development programs over the years with limited but gratifying success. MOST of my contemporaries were not beneficiaries of the education one gets when as the ONLY electro-wiennie in the building, I tracked a product from conception all the way through prototype, meeting requirements milestones, customer approval, qualification, procurement, manufacturing, quality assurance, shipping, customer service and warranty. Without this broad perspective, it's difficult to see how the saving of a few dollars now can translate into greater expenditures when the end-to-end costs of the product are considered. Are there no in-country electronics distributors that offer low cost tools like: http://aeroelectric.com/Pictures/Tools/Crimp_Tools/4-Quad/rct-3.jpg Surely many fellow citizens could benefit by a local business adding this product to their catalog. The machined pins can be breathtakingly priced in this country. Allied Electronics prices them at 52 cents each in their catalog and they drop only to 30 cents or so in 500 lots. My distributor will sell me a bag of 5,000 pins for about 15 cents each. Your local suppliers could offer these pins at pretty attractive prices if they shopped around a bit for sources.

Some submini D connector contacts will not fir the shell of other manufacturers. Also, different connectors pins for different wire size, i.e., 22 ga vs. 18ga. At least for the larger circular connector series from AMP or Amphenol, the pins are color coded with tiny bands. Of course the companies don't make it easy to discover the color code meanings!

Switch goes open circuit (or intermittent) and your engine will quit...this is a very bad idea..Almost as bad as having a single fuse serving both ign itions..Don't do it! Both ignitions must be wired completely seperate...wiring, fuses, switches. Incidently the E/Pmags are wired like a regular mag, but I still switch the m seperate.

It's not a big secret. Most pins offered for military spec'ed connectors are in the Mil-C-39029 family of devices. In particular, the 20AWG standard density d-sub pins are 39029/64-369. See: http://www.aeroelectric.com/Pictures/Connectors/D-Subminature/D-Sub_20AWG_Pin.jpg similarly, sockets are 39029/63-368 http://www.aeroelectric.com/Pictures/Connectors/D-Subminature/D-Sub_20AWG_Socket.jpg Note that in both cases, the color banding on the pin barrel uses the legacy electronic components color code convention shown below. Emacs! In the case of the d-sub pins, the color bands denote the last digits after the dash in the full part number. I'm aware of no cross-reference list that will let you back into the application of some stray pin. However, if you go to a particular connector's specifications, the pins for each hole along with the wire-gage range for that pin will be defined. I'm aware of no ambiguity in 20 or 22AWG d-sub pins for marking or application. If you have a pin that doesn't fit the hole in a D-sub of one brand, then it's not a d-sub pin for any brand.

Many of the push button and/or toggle switches on the Infinity grips have two wires and most functions they control simply require a connection to a ground when activated (like PushToTalk, AP disconnect, Freq swap, etc.). Plus the trim switch (coolie hat) has one connection labeled common or ground. My question is, as a general rule, would it be better to connect those switches (needing a ground) to the airframe (under the seat somewhere in this case) or carry a single ground wire back to the forest of tabs (or avionics ground "bus")?

Hi Allen (From another Subbie...) I am not an EE or a specialist, but I did connect all grip ground wires to one ground bus under the seat, and then carried a single ground from that bus to the firewall forest of tabs. It works flawlessly, but I did some tests grounding each of the wires to the airframe locally and worked good as well.

These are control lines, not signal lines. Further, they carry very little current. They will perform as advertised with local ground. The only caveat might suggest that each ground wire from each switch get its own ground wire through the maintenance connector . . . and have it's own terminal to the ground stud (8-32 screw). This will prevent loss of one wire causing loss of all control functions on the stick that use a ground for operation.

Z-24 has been moved to here: http://aeroelectric.com/articles/Adapting_IR_Alternators_to_Aircraft.pdf Z-24 is an acceptable means for controlling the IR alternator in the manner common to aircraft where the alternator is not turned on or off while at high engine rpm and/or under heavy load. I offer this caveat only because there is a small chance that any given IR alternator is not designed for protecting it's own regulator under severe load- dump conditions. Having written that, I can tell you that IR alternators from most sources will stand moderate to severe load-dump. The Z-24 architecture will smoothly transition into incorporation of the AEC9004-1 controller should you elect to upgrade at a later date.
