From: GTH Le 10/01/2017 05:19, user9253 a crit : > > Gilles, > I modified your schematic and added information gleaned from Rotax-Owner.com. > As for over-voltage protection, an alternator switch could be inserted in the wire going to X3.3 It might take you a minute or two to recognize the over-voltage condition and shut off the switch. But most modern avionics are rated up to 30 volts. And the battery will resist the increased voltage for a while. Hundreds of RV-12s are flying without over-voltage protection. I am not necessarily recommending not installing over-voltage protection, but it is an option. Joe, Thank you for having taken the time to examine and comment the schematic. You are right, most avionics can withstand up to 30 V, but unfortunately not all of the appliances in the project, and my partners are asking for some protection. Initially I thought that the built-in Rotax OV protection would be enough, but as some owners had over-voltage events, obviously the voltage regulators can fail (there has already been a regulator update by Rotax), and the OV protection did not catch or contain the event. So I'm wondering... Thank you for your help, -- Best regards, Gilles http://contrails.free.fr http://lapierre.skunkworks.free.fr ________________________________ Message 2 _____________________________________ Time: 05:20:34 AM PST US From: "Robert L.

Okay, it is my understanding that P-P brings field supply lead out for ABSOLUTE alternator control. Hence, leaving the alternator side of your split rocker OFF should relieve the battery of an unnecessary load during ground ops . . . and leave your alternator cool.

The very.VERY.BEST thing in addition to the delete key is to exercise the "report as spam" key and the blueberry gets squashed locally in your computer.and then the wonders of Norton or your favorite anti-spam software will report Mr. Blueberry to the collective and then other local computers will automatically step on the blueberry. Then of course the process repeats. .. Cheers!!! Bill Hunter From: owner-aeroelectric-list-server@matronics.com [mailto:owner-aeroelectric-list-server@matronics.com] On Behalf Of Robert L.

Since then, I don't know if happened again or not. Not being computer savvy or techno competent, I pondered what to do to protect my email and address book from a nefarious hacker. Password changes were not a satisfactory solution. I was hacked 2 days after a change. I considered leaving my address book blank and typing the address for every email I sent. That quickly became a royal PIA.. So what could a nontechy do? I have added an extra integer-letter or number- to every address in my address book. Should I be hacked again and I'm confident I must have been, the hacker will only get a list of addresses that are useless. I know this because I occasionally forget to remove the extra integer or integers when I send a message and it bounces back with "this address does not exist". It has been many years since I last was embarrassed by seeing my email used by a hacker. It is a small inconvenience to remove the added integers before sending a message, but it's a low tech solution that has worked for me. Now I hope I have not jinxed myself by making it public. jrh ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message aeroelectric-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/AeroElectric-List.htm Web Forum Interface To Lists http://forums.matronics.com Matronics List Wiki http://wiki.matronics.com Full Archive Search Engine http://www.matronics.com/search 7-Day List Browse http://www.matronics.com/browse/aeroelectric-list Browse Digests http://www.matronics.com/digest/aeroelectric-list Browse Other Lists http://www.matronics.com/browse Live Online Chat! http://www.matronics.com/chat Archive Downloading http://www.matronics.com/archives Photo Share http://www.matronics.com/photoshare Other Email Lists http://www.matronics.com/emaillists Contributions http://www.matronics.com/contribution ------------------------------------------------------------------------------------- These Email List Services are sponsored solely by Matronics and through the generous Contributions of its members.
