What you describe is how the switc h *should* operate, but it's easy to verify operation for yourself. Without t he P leads connected to the switch, Measure resistance from each P lead term inal to the ground terminal, 1st with the switch 'off', then in 'L', then in 'R'. Both P lead terminals should show dead short to the ground terminal wi th the switch 'Off'. The 'L' terminal should show an open circuit (infinite ly high resistance) and the 'R' terminal should show a short to ground with t he switch in 'L', and the reverse in 'R'. With the switch in 'Both', both te rminals should show open to the ground terminal. (Don't forget that if you'r e touching the terminals with your fingers, your body will conduct slightly, so depending on the meter, you might see some high but not infinite resista nce when the switch is open.) > > The left mag is *typically* the impulse mag, but it's pretty easy to check . The impulse mag has what appears to be a spacer that's about an inch thick between the body of the mag and the engine. So the 'taller' mag is the impu lse mag. > > Charlie > > Virus-free. www.avast.com ________________________________ Message 2 _____________________________________ Time: 05:10:30 AM PST US Subject: AeroElectric-List: Re: Transponder and/or ADSB Antenna Installation and Radiation From: "Beauvais" Basic economics tells us how important receiving a quality education is for bettering ourselves and the future of our children. Education enables upward socioeconomic mobility and is key to escaping poverty. It is also essential for empowering people globally to live more healthy and sustainable lives CLIK HERE (https://www.newsblogged.com/why-successful-entrepreneurs-prioritize-philanthropy/) Read this topic online here: http://forums.matronics.com/viewtopic.php?p=497461#497461 ________________________________ Message 3 _____________________________________ Time: 07:39:56 PM PST US Subject: AeroElectric-List: Re: Z11 field supply circuit protection From: "draker" Thank you, very informative answer. I erroneously assumed that a breaker or fuse protected the whole circuit, not just what's downstream from it. Rookie mistake. About the field supply current: It makes sense that if the field current draw is accounted for by the alternator's advertised output, then you wouldn't include it in your energy management calculations. Question is, how do you know if a particular alternator accounts for it? Is this standard alternator marketing practice? Do B&C alternators account for it? Will I get 40A out of a 40 or will I get 40A minus field current?
