Exactly. There's another important component to this discussion. The List is not just a place to ask, "what's 2 + 3 and where do I buy some 3's?" It's a classroom where about 1400 individuals watch the proceedings and take away buckets of simple-ideas along with a few recipes for their utilization. Whether we're cooking stuff up on the stove, writing software, or configuring an electrical system, the elegant solution will be elusive unless the 'chef' understands exactly how all the ingredients behave as individual components and then in combination with each other. In this class room environment there is, and should be, a high probability that any questioner may be asked to stand up in front of the class and defend his/her recipe for success. My bosses called this process preliminary, critical, and qualification design review. A means by which ideas could oscillate between any constellation of extremes as collegial argument deduces the elegant, lowest risk way to meet customer design goals. There is a risk that some questioner will feel picked on or belittled. I'm probably as guilty as any for not always making sure that the questioner understands this process along with his own, important role in this sharing of knowledge. Mr. Ryan has states some ideas and goals and he has been asked to share his supporting thought processes. Of course, nobody will be insulted or even disappointed if he declines. At the same time, everyone interested in the conversation may harvest and exploit any number of simple-ideas supported with examples of how they fit together.

My aircraft French DynAero MCR-4S is advanced avionically and uses as it base Bob's infamous architecture. I do not have the external alternator as it is unnecessary (for me). On the primary bus I use a Vertical Power VP-X (serial connect for laptop control) and good old automotive fuses on the endurance bus. The VP-X controls the relay for alternator disconnect. This is a very stable environment with no problems of any sort. Happy to share my schematics. Cheers Peter -------- Peter Armstrong Auckland, New Zealand DynAero MCR-4S (Do not shoot me :) ).

I have the Z-34 set-up of two (2-3) magneto switches and a push button for the starter. Note 3 for Z34 advises grounding the shield to engine ground at the mag end. On a previous post I found this: I recommend each mag switch get grounded through the shield of the p-lead where only the mag end of the p-lead shield goes to the crankcase or other handy fastener on the engine. Bob . . . On the mag case an inch from the P lead post there is a handy #8 screw labelled GND. The case is intimately attached to the engine. Can this GND screw be the handy fastener on the engine where the P lead shield is grounded when wiring a mag switch per Z34? On the switch end, the same P lead shield gets attached to terminal 3 of the switch, right? Eric S. The mag pictured is not mine but is like the one I have and is for illustration only. No advertisement intended.

Yes . . . or to any other 'handy' ground to crankcase . . . doesn't have to be on the mag nor is it prohibited to extend the shield ground with a pig-tail long enough to find a more remote ground. But it looks like your best option is nicely located. On the switch end, the same P lead shield gets attached to terminal 3 of the switch, right? Yes . . .
