You still need two switches as this schematic does not show the switch to engage the starter. The switch in this schematic simply selected between start power and backup power, but doesnt address the need to hold the start power switch while keeping one hand on the throttle and a third hand to engage the starter. :D Read this topic online here: http://forums.matronics.com/viewtopic.php?p=511215#511215 ________________________________ Message 2 _____________________________________ Time: 06:13:41 PM PST US Subject: AeroElectric-List: Re: Simple sequencing using common 5-pin auto relays From: "user9253" You are right Matt. I did not read your original post carefully enough. You wrote, "mounting one as a toggle switch sideways that can be pulled towards a guarded starter button. . . " I think that is the best solution instead of complicating the circuit with relays or electronic timers. My 912ULS also requires 3 hands to start. One hand pulls the choke, one hand turns the start key. It starts within 2 seconds. Then I have to push the choke in and lock it while simultaneously advancing the throttle. It is not easy, but doable. -------- Joe Gores Read this topic online here: http://forums.matronics.com/viewtopic.php?p=511220#511220 ------------------------------------------------------------------------------------- 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.
