Hi Steve,   I sent it to the list just before leaving on vacation.  Unfortunately I later found that the message got bounced for size limitations.  Can't seem to edit it down to size on this iPad so will do that when I get back in August.   Will see if I can find a picture editing utility that works on iPad and maybe get it done sooner.

My RV4 & 8 have just the basics,  stock RX-7 alternator and a single battery that I check for capacity every annual.   The significant details are in the PHYSICAL details of the layout.  Digital electronics and inductive spikes from coils, solenoids, injectors, etc see a long wire as an open circuit during the first few nanoseconds.   This is the factor that is most difficult for builders not familiar with electronics to understand.  This isn't important with carburetors, distributors & points or magnetos but when you introduce a digital computer into the mix it's a different story.
