After di-secting the old push button starter, I decided I'd never want it as part of my circuitry again. The PA-22 (mine, anyway) did not have a starter contactor, so contact was only as fast as my finger could close the gap. The degraded condition of the contacts suggested that wasn't fast enough. Adding that problem to the problematic long length of the cable from the bottom right seat area to the starter button and then on to the starter and I finally knew why my starter never exibited any signs of glee when I mashed the button. I had already planned to replace the old starter button with a starter contactor (available reasonably at B&C or elsewhere) and a small dash mounted button. For the money, I'd recommend that change to you as well and for sure consider what Bob has suggested about the old battery. My old style is going away and will be replaced with a new any position battery; it will be located in the left boot cowl area with access via a door on the boot cowl. Am still in the design stage for the mount. Good luck on your changes.

We have a keyed switch but it is kind of nice to have the button under the seat, most people can't figure out how to start it. Good luck with your battery relocation. Do you have the stock starter, if so have you looked at a Sky-tec starter yet? A big improvement.

Yes! Just one more way of holding them together. All depends on application and preference!

The strain relief wraps of tape should be just snug in the backshell opening as you've discovered. An exemplar installation is illustrated on page 2 of this work instruction. http://aeroelectric.com/Catalog/AEC/9051/9051-700A.pdf Bob . . . ----------------------------------------) ( . . . a long habit of not thinking ) ( a thing wrong, gives it a superficial ) ( appearance of being right . . . ) ( ) ( -Thomas Paine 1776- ) ---------------------------------------- ________________________________ Message 9 _____________________________________ Time: 06:30:42 PM PST US From: "Robert L.

I've also used a figure-8 wrap of safety wire or flat lace to bind the the two connectors together in lieu of jackscrews. >I suppose that if you're worried about hoods falling off the D-sub >(which I've never seen happen), you could replace the screws with >zip ties though the screw holes and around the hood. This was a case of over-stressing the hood material because the wire-support wrap was too fat.

They're not critical to the correct operation of my electrical system, so continued to hack my way through. Many broken pins, snapped wires and sockets with stuck pins later, I finished and got everything working. But when time allows, I'm going to redo it all (using the CORRECT equipment and parts), because although it works for now, I don't think it'll last more than a couple of years in the high-vibration environment. Another frustration I had was once everything was crimped and all the pins were pushed into the sockets, the damned things wouldn't fit together! There is so much play within the support for the female pins, that it allows them to move out of alignment with their male counterparts. So don't waste your time and effort, do it right first time. The frustration of getting a crimp right using cheap tools and parts alone is enough to cover the outlay for the good stuff!
