I currently have the ground plug installed( Piper variety), but the plug centre positive terminal is live, so its easy to charge the battery aswell as jump start the engine if master is left on. If I add the extra Relay ( Ground Plug) with diodes and wiring as per Bob Nuckolls drawing, I can see jump starting will be ok when connected and ground power switch on. But, I cant see how connecting a battery charger to the postive and earth of ground plug will allow current to flow to the battery for charging. I have tried 2 differing chargers to activate the solenoid switch and found this did not work ,with one charger I used. Can you please advise me how I can use any battery charger to activate the ground plug relay to charge my LiFPO4 battery( usually after using Electrical gear in cabin on ground) thanks Jeff R Australia -------- JKR Read this topic online here: http://forums.matronics.com/viewtopic.php?p=510906#510906 ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message rv7-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/RV7-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/rv7-list Browse Digests http://www.matronics.com/digest/rv7-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.
