Isn't the admonishment, to never start the plane with the electronics turned
on, contrary to the threads that hold that the new electronics are pretty
impervious to the spikes associated with startup, or did I miss something?
Or just a difference of opinion?

You should never start the plane with your electronics turned on. You get a
big inductive spike when ou do that.

Subject: AeroElectric-List: when running my new B&C starter the lights
go out..
--> AeroElectric-List message posted by: "Matt Luthi" <mluethi@bigpond.com>
I just connected my new B&C starter motor to the electrical system and
tested it without the flywheel installed. When I engage the starter motor
all my gadgets (GRT EFIS, EIS, Skymap IIIc GPS) don't like this very much
and reboot. It looks to me as if the bus voltage drops too much for them to
keep running. This is only just for the moment when I engage the starter. I
kept it running while it ran all the electronic gizmos come up again fine.
1. I have a new Odyseey PC680 battery, charged, indicating 12.8V
2. The EFIS and EIS are always on when the master switch is engaged (no
avionics master)
3. I followed the "all electric aircraft on a budget" approach religiously.
Questions:
1. Is this "normal" behaivour?
2. I have dual Lightspeed ignition without a backup battery - I have the
SD-8 PM Standby Alternator for redundancy but now after I have read the
posts about the "kickback" problem experienced on EI systems during cranking
and resulting low voltage I am not so sure that this is a good setup for my
starter motor. Should I wire a backup battery with a diode to one of the LSE
units?

I idiotproofed (no guessing) my electronics by wiring a 30-40 amp ice cube
relay in paralell with the starter relay. I used the NC contacts so that
when I start the engine all the electronics are DISCONNECTED. If you
accidentally hit the start switch with the engine running this will really
save your wallet !

You guys know that the electronics can be designed such that they operate
while starting the engine.

True enough but the only thing that slightly worries me is that I notice
that all modern autos
switch off the radios when starting. Are they being over-cautious?

There's only one ACCESSORY circuit on a car and some of the loads on it are
substancial. I believe the accessories are swithced off to reduce the load
on the battery in the START mode.
