I need a smaller right coil and hall effect sensor for a 2200 Jabiru
engine. Bob Haas, checkpoint3(at)comcast.net. FL. USA.

Hello Robert,
The coils are standard parts for Jabiru, there are no big and small
versions.
What problem are you trying to fix?

Greetings , I need a thinner dimension where the
coil attaches to the stand off mounts on the rear in order to run a
alternator belt to a pulley
mounted on the end of the crank. It seems that the alignment of the drive
pulley , interferes with the driven pulley on the mounted alternator.
If I could fine a hall sensor that would mount at the original position,
then I could locate the coil nearby and supply voltage to the distributer.

The location and dimensions of the coil are crucial to proper spark
timing, you cannot just move it around to some other position. I'm not
sure if you are trying to re-invent the wheel, but there are two
companies already selling belt-drive alternator conversions that fit the
engine as-is:
CAMit:
http://camitaeroengines.net/collections/ancillary-parts/products/kit-alternator-40amp-2200
Rotec: http://www.rotecaerosport.com/products/jab/alt/
If you are looking for just a bit more current than the older 10A
generator provides, then you can opt to get a 20-25A Jabiru generator
which fits right onto the flywheel.

Rob, I understand Hall effect works. There is an option, look at the
Rotec E-ignition upgrade, and notice the components. The hall effect
sensor is remoted via the ignition module to the coil. The Hall sensor
triggers the coil because it is positioned as the original coil magneto to
the
fly wheel. What is the origin of that set up? Where did Rotec find it?
Where can I buy one here in the States? Thanks for your insight to my
problem.
Bob Haas.

Hi Robert,
I own a Rotec ignition set, so I have used that hall sensor. Rotec
produces them themselves. They machined a simple aluminum bracket, then
potted a standard hall sensor (looks like TO-92 transistor) into a
little cube and mounted it on the bracket. It is crude but it works.
With the original Jabiru ignition coil, the magnet on the flywheel
directly generates the energy to produce a spark. With the Rotec sensor,
the magnet is only used to sense the position, the spark is produced by
a separate ignition module and ignition coil. Rotec has used this
combination of sensor, ignition module and coil for their radial engines
and adapted the sensor for use on Jabiru engines later on.
The Rotec hall sensor is indeed much smaller than the Jabiru coil, so if
that fixes your problem, go ahead and buy their kit. They are happy to
send one across the pond. As a bonus you get better cold weather starting.

Hey Rob, Thanks for the info, It never gets below 40' here in SW FL, so
starting is no factor. I bought the alternator kit from Rotec, it is a good
kit
and value for the money. But , when I told them it would not work on my
Alpi Pioneer, the quit talking to me. That explains why I cant fine a
commercial
application. I will purchase the Ignition if I can't come up with some
thing else. Thanks again, Bob Haas.
