Got them Ed, and thanks. One quick question. I went to an AOPA safety seminar, and they recommended a separate ground switch for the GPS, and related equipment, so that they could be programmed without the engine running, as that has been known to take some time, and your head is down with a prop running. Has anybody done this? Any diagrams?

Yes, my switch will stay in Alternator position even with a diode - because even a diode can fail and I really dislike repeating incidents due to the same cause {:>) Ed Ed Anderson Rv-6A N494BW Rotary Powered Matthews, NC eanderson@carolina.rr.com http://www.andersonee.com http://www.dmack.net/mazda/index.html http://www.flyrotary.com/ http://members.cox.net/rogersda/rotary/configs.htm#N494BW http://www.rotaryaviation.com/Rotorhead%20Truth.htm -----Original Message----- From: Rotary motors in aircraft [mailto:flyrotary@lancaironline.net] On Behalf Of Ernest Christley Sent: Saturday, June 06, 2009 4:23 PM To: Rotary motors in aircraft Subject: [FlyRotary] Re: Battery Isolation diodes Ed Anderson wrote: Thanks, Tracy I was unaware (never thought about it) of the association - perhaps not having an isolation diode is one reason I never had any "Noise Problem" with the EC2 {:>) Thanks for the information Ed When wiring up the diode, it should be fairly simple to drop in a large value mylar capacitor to conduct the noise. My experience with electrolytics is that they can be poorly made and leak. The mylars would be more robust in the environmental extremes of an airplane. In any case, I thought the diode was just for a backup. The switch would stay in the same position it has always occupied, so noise would be absorbed by the battery as it always has. The EC2 would have to be on the battery side of the switch, which would make it even more noise isolated when hidden behind the diode. -- http://www.ernest.isa-geek.org -- Homepage: http://www.flyrotary.com/ Archive and UnSub: http://mail.lancaironline.net:81/lists/flyrotary/List.html __________ Information from ESET NOD32 Antivirus, version of virus signature database 3267 (20080714) __________ The message was checked by ESET NOD32 Antivirus. http://www.eset.com __________ Information from ESET NOD32 Antivirus, version of virus signature database 3267 (20080714) __________ The message was checked by ESET NOD32 Antivirus. http://www.eset.com -- Homepage: http://www.flyrotary.com/ Archive and UnSub: http://mail.lancaironline.net:81/lists/flyrotary/List.html
