| Subject: | Re: PMag Preflight Check |
Peter and Mike,
I must have misread your postings. 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.

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.

| Subject: | B and C SD8 Alternator |
Having read the discussion this topic regarding Running Lights (Nav Lts?)
and the pro-/anti-Whelen sides, it occurred to me that perhaps another tack
be taken.
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.

| Subject: | RE: AeroElectric-Z13/8 ???? |
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.

| Subject: | Z-19 Clarifications |
Hi ,
I am planning to install a Z-19 system and had a couple of clarifying questions.
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.
Thanks very much,
Mike
