Normally the only thing electrical that is turned on via switches prior
to cranking the engine is the beacon. I killed the beacon...still, two
blades and no more. I then thought I'd kill the alt half of the master.
On the next start attempt, it fired right up. I don't remember if it was
after two or three blades. Maybe coincidence, maybe not having the t/c
gyro and everything else electrical that doesn't go through the avionics
master did the trick.

I know what I am going to type is counter-intuitive, but hear me out.

If you run into a battery that is not quite up to the job of getting enough
cranking speed, try the following procedure.

If it does not catch as quickly as it usually does, before you kill the
battery, stop-turn everything off, for two minutes. Look at your watch, or
timer. After the two is up, turn on your landing light, for one minute.
Again, time it. Turn everything off, and immediately try turning it over to
start. It will turn over faster than it did the first time.

The theory is that putting a relatively small continuous load on the battery
heats it up a bit, without taking too many amps out of it. The warm battery
will now be capable of putting out more amps than it could at the
temperature it was before.

Anyone else ever hear of that, or do this procedure before? It has worked
for me.

I have heard of (probably on this group a couple years ago) but have
never tried it. Cold starts depend on the amount of priming, also.

Jim, I've used that "trick" many times. If you live up here in the
frozen tundra it will make you a believer. I've used it successfully
on trucks, tractors, garden tractors, and the Aztec. I've haven't
heard that it makes the battery warmer, but rather that the draw
causes the battery to "wake up" and re-charge itself. Suposedly the
draw from the starter isn't long enough to "wake up" the battery.

I didn't always live in NC! Ohio most of my life taught me a few tricks.

I don't believe a battery "wakes up" or there is anything that could be
going on to chemically "recharge itself."

It is a know fact that a warm battery performs a measurable amount better
than a cold battery. A sustained draw does heat up a battery, so therefore,
I believe that the "warming up the battery" is what is really happening.

You're right, a warm battery definately has more CCA than a cold one.
The "wakes up" theory was presented by Click and Clack on their NPR
radio show a couple months ago. I've used the procedure for years, I
wonder if google has the answer?

Forgive me Father for I have sinned!
It has been three months since my last flight.

You are forgiven, my son -- but only if you perform the following
penance:

1. 3 "Hail Mary" simulated engine-out landings...
2. 2 "Our Father" cross-country flights...
3. 1 "Rosary" Young Eagle flight...

And, finally, don't forget the "Stations of the cross"-wind
landings...

Okay, I have the Our Father and Stations of the Cross covered, but
what's your wife have to do with simulating an engine out? :-)

You clearly haven't flown with Mary!

Ow! Ow! Ow! Dang it, she wasn't supposed to *see* this!

admit it, Mary doesn't read usenet. You get to say just about
anything about her flying and she'll never know by reading
it on usenet.

Jay's version of a Hail Mary: The fan in Atlas quits...silence for a
couple of seconds then Jay says to Mary "Your airplane".
