I measure the voltage drop in the iron bolts last year : about 1 V (low
section and low conductivity of the iron) !
You don=92t need a strap. You just have to connect the ground near the
brushes
of the starter :

Ale,
The problem is not the starter motor or the battery, it is caused
because
the engine gets very tight when warm.
The cylinders cool faster than the pistons and you can confirm this by
hand
propping next time it happens. You will find it very difficult to turn
over.
I have over 30 hours but still have the problem but I was advised by the
factory that this is a sign of a good engine. It would not be possible
to
restart my engine in flight. Even if it would crank it is too slow to
activate the magneto spark.
It is possibly also true that starter motors vary in efficiency.
We need to get best possible advantage from the starter motor by
mounting
the battery with short leads (if possible). I also found that the two
starter motor mounting bolts get very hot. They serve as an earth but
they
are fitted with Loctite and not well earthed. I added a separate earth
strap
from the brushes end of the starter motor to earth for some improvement.

Hello Alberto,
Sorry I was not able to get back to you. We left to catch a flight to
BCN
immediately after writing to you. I wanted to discuss the starter motor
on
the J3300. I have replaced three batteries because the engine would not
restart after running for awhile. I've finally reached the conclusion
that
the problem is not the batteries but the starter motor. After running
the
engine the starter motor gets very hot. This, of course, increases the
resistance so that all the current going into the starter motor is
trying to
overcome the high resistance. Anyway, I'm now looking for a replacement
starter motor.

Dale

The brushes are located between the two bolts head. So, when you ground
the
engine like that : <http://dl.free.fr/pJnfGsBU5>
http://dl.free.fr/pJnfGsBU5 (the ground on this picture is the black
wire)
you can avoid voltage drop in the bolts of the starter.

Fellows,
I can't help but think you're chasing a lot of dead ends here. So with
that said and bringing your immediate suspicion to what I'm going to
say, I'll say it anyhow.
Hot starts a problem? This is what I read.
1. When parking for a while, do you open the oil cooler door to allow
hot air to escape? Point nose of a/c into prevailing wind?
2. You must have the hole in each RamDuct just before cylinders 1 and 2
to get some air over the case, onto the starter, and more importantly
onto the coil behind cylinder 5.
3. Epoxy/flox a 3/4 inch "blast tube" to the back of left RamDuct and
have it directed to the coil that is almost hidden behind cylinder 6.
4. Have an Odyssey battery, 625 or 680. Anything else and you're
batting gnats with a toothpick.
5. The reasons behind numbers 2 and 3 above are that the coils in the
3300 tend to break down under heat - then magically become workable
after cooldown. I know, I've had two of them. Replaced both and was
not at all happy with the price, not at all.
It may not be a starter problem. I have the old, old starter (engine
051) and won't replace it until it dies, and with 335 hours on it, it
shows no sign of malaise. That new starter would be nice, Heck, even
the ungraded Bosch would be great, but at the price someone quoted on
here Jabiru must think their customers are made of $$$$.
If anyone find the cross-reference numbers for that starter so I can go
to Kubota or elsewhere and buy one, please post it.
Remember what you paid for the above info...

Jerome,

motor than mine. The one I have is all black and, I'm told, that it is
manufactured by Bosch. I believe the new ones are Nippon -Denso.

Thomas,
You have not referred to the most common cause of the problem which is that
the engine gets very tight when it stops because the barrels cool quicker
than the pistons and grip the pistons tight. Hand propping soon after you
shut down will show that some engines (mine) gets so tight it is difficult
to turn over and you cannot "feel" the compression.
I have confirmed this with advice from the factory, they say it is a good
sign for a tight engine.
Consequently although it is good practice to make life easy for the starter,
the problem is not the starter.
As a matter of interest more recent engines with additional cooling fins
have suffered from the reverse problem. On climb out the cooling fins are so
effective that the pistons expand under heat into the well cooled smaller
barrels. We have had an instance when the piston head came off in initial
climb out . These engines should be carefully ground run and maybe due care
with limited throttle for take off during the early run in period.
JMHO.
Peter

Fellows,
I can't help but think you're chasing a lot of dead ends here. So with that
said and bringing your immediate suspicion to what I'm going to say, I'll
say it anyhow.
Hot starts a problem? This is what I read.
1. When parking for a while, do you open the oil cooler door to allow hot
air to escape? Point nose of a/c into prevailing wind?
2. You must have the hole in each RamDuct just before cylinders 1 and 2 to
get some air over the case, onto the starter, and more importantly onto the
coil behind cylinder 5.
3. Epoxy/flox a 3/4 inch "blast tube" to the back of left RamDuct and have
it directed to the coil that is almost hidden behind cylinder 6.
4. Have an Odyssey battery, 625 or 680. Anything else and you're batting
gnats with a toothpick.
5. The reasons behind numbers 2 and 3 above are that the coils in the 3300
tend to break down under heat - then magically become workable after
cooldown. I know, I've had two of them. Replaced both and was not at all
happy with the price, not at all.
It may not be a starter problem. I have the old, old starter (engine 051)
and won't replace it until it dies, and with 335 hours on it, it shows no
sign of malaise. That new starter would be nice, Heck, even the ungraded
Bosch would be great, but at the price someone quoted on here Jabiru must
think their customers are made of $$$$.
If anyone find the cross-reference numbers for that starter so I can go to
Kubota or elsewhere and buy one, please post it.
Remember what you paid for the above info...
