Nuckolls, III) ________________________________ Message 1 _____________________________________ Time: 08:02:57 AM PST US Subject: AeroElectric-List: Re: What makes diode get warm From: "rvg8tor" Bob N. When I looked at the B&C website for my diode the install instructions for the diode said for an E-bus drawing more than 3 amps to mount the diode on a heat sink, my E-bus will draw 9 amps. So I bought he diode already mounted to the heat sink, I did not think about the fact that just mounting it to the metal panel would provide some heat sink capability. I have read many posts with regard to E-bus design, my goal was not to fly to my destination if I was battery only but to be able to fly to suitable field, not necessarily the closest field and land to make repairs. In all honesty I think I may never see battery only when I consider the probability of losing both main and standby alternators. I like the insurance of the standby alternator when I consider IFR operations, this is my main reason for adding this to this and hence my adoption of Z-12. Thanks again for the help you provide it is much appreciated, I have been learning a lot. -------- Mike "Nemo" Elliott RV-8A QB (Fuselage) Read this topic online here: http://forums.matronics.com/viewtopic.php?p=269970#269970 ________________________________ Message 2 _____________________________________ Time: 03:47:11 PM PST US From: "Robert L.

Then leave the e-bus out. There are thousands of Bonanzas, and large Piper/Cessna singles wired like Z-12. This pre-supposes that you're not interested in the pre-flight power up of a comm radio before starting the engine. Z-12 Works good, lasts a long time.
