I have the complete installation manual. It has a number of pinout diagrams showing connections to various indicators etc. But nothing that explains what the various King signals do. A schematic would be very helpful. Thanks all, Steve Maher San Diego, CA __________________________________ http://advision.webevents.yahoo.com/yahoo/votelifeengine/ ________________________________ Message 2 _____________________________________ Time: 08:22:11 PM PST US From: "Paul Schattauer" Subject: RE: AeroElectric-List: Alternate static source --> AeroElectric-List message posted by: "Paul Schattauer" Fergus Icing of the static ports is uncommon but if you are worried about it and plan to fly IFR...install an alternate static valve in the cockpit and just test fly the indications with both sources, I don't think you will find much difference. But whatever the difference is you will know it and be able to compensate for it. My solution was a Gretz aero heated pitot and static tube all in one.

The power supply I have is 12v DC with no other adjustments. I am however willing to purchase another unit if necessary. Many Thanks Mickey Billings RV&
