That's easy to do sometimes. I haven't had the pleasure of flying the same aircraft all the time - not to mention one I built. So, I can understand getting to know the airplane very well and not needing a complete check on every takeoff. Stan Sutterfield Do not archive I don't think I recommended not to check the internal generator, just that I don't do it. The generator is a back-up to a back-up, as the ignition typically uses power from the alternator, then it could use battery power, or it could use generator power, and the engine will continue to run on the magneto alone in a pinch. There is certainly nothing wrong with checking it every flight, I just don't do it. My choice is not to do a complete run up check on (usually) other than the first flight of the day, I check for dead cut, check for normal temperatures & pressures, carry out the normal before take-off checks and go - probably my glider towing background showing through. I have nearly 300 hours on the aeroplane and am familiar with the normal feel and have seen/felt/heard several abnormal 'feels'. I don't get too bunched over systems check when the systems have show themselves to be reliable in my aeroplane, operated the way I operate it. http://discover.aol.com/memed/aolcom30tour ________________________________ Message 2 _____________________________________ Time: 05:11:38 AM PST US From: "David & Elaine Lamphere" Subject: Re: AeroElectric-List: KX125 connector Ah yes!

The coloured lights are there so that (like ships) an early estimate of direction of travel be made in order to plan evasive manoeuvres if needed. In that case, the lights are not just for our protection but for the Others out there. That's what I think the U.S. regs require - service to other flyers. If they don't satisfy the particular standards drawn up, they don't protect other aircraft - and that could be 300 people..... That's why I've chosen an approved source for lights.

I am wiring my RV7A using Z 13/8 as my basic scheme. I did change the scheme to use Z-25 as the SD-8 Aux Alternator controller and the B&C LR-3 as the controller of the main alternator (as shown on Z-12). I also have the Dynon EMS-120 which has an ammeter shunt to monitor electrical flow in one of three locations. I have choosen to place the shunt in the A position to monitor current flow into or out of the battery. Now the ??????? 1. With all this said I would like to eliminate the two shunts that monitor the SD-8 and Main alternator in in their place use the inticator lights. Does this make sense? My argument is I just want to know when the failure of an alternator occures and then monitor battery current specifically. 2. Does the indicator light attach to the S704-1 at the NC location ......assuming that 1 above is ok to do. Thanks in Advance for your help.

Feedback is very much appreciated. 1. Do all of the contactors in the system have to be Amperage rated at or above the maximum output of the alternator? I guess this is not a z-19 specific question but I'm still unsure. 2. How does the E-bus alternate feed relay work, I am not sure of its intended purpose? I can see the E-bus is normally fed from the Main power bus through a diode but I'm not sure what function the relay provides. Do you normally start with the E-bus relay switch OFF. Then if your alternator dies you manually switch the E-bus ON? My E-bus load comes up to 9.5 amps. Do I even need the relay? 3. Should both batteries be connected to the same ground point on the airframe, rather than two separate locations? In my case it means running about 5' of wire to that designed ground stud. 4. Parts - Diodes for the ECU and Fuel pumps - is the B&C Essential Bus Diode and the Perihelion Power-Deuce-Schottky Auto-Power Selector Diode Assembly essentially the same component. In the Z-19 the it says 'Note 24', but I cannot find that in my Aeroelectric Connection manual or the website.
