Greg, I have fuses going to the EC-2 and the coils, if I had CB's I could switch off the CB's, now I need to pull the fuses, another good reason to use CB's.

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?

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 -- Homepage: http://www.flyrotary.com/ Archive and UnSub: http://mail.lancaironline.net:81/lists/flyrotary/List.html
