Hmmmm . . .is the "stock" permanent magnet alternator
still in place on the flywheel?

If you still have the PM alternator, then 13/8 looks
attractive. The PM alternator is good for 18 amps
or so.

As a battery contactor? No. How close is your battery
mounted to where you sit? Can you consider a manual
battery switch?

Hmmmm . . . 12A seems like a LOT of energy for
a system this size. Do you know anyone who is flying
or at least doing ground runs on this engine? It
would be VERY useful to do your deliberations with
REAL numbers.

Which sensor? Most engine management systems will have
several. Further, the panel mounted instrument is tailored
to both the scale factor and power requirements for
any particular sensor. The probability is that the
two different systems are not identically configured
for a particular parameter. There are no "standards"
for the selection of sensors.

To all Listers:
who are using my sketch of the Bussman terminal removal tool to fabricate the
part.
There is an error on the sketch. In the side view the .40 dimension should read
.04
Sorry for the error

Chris -
In this series of Bussmann fuse blocks, there are a lot of variations of
size and configuration. This is a modular line of blocks. We have two
20/8's installed in our Lancair ES. They are really great items. Each
comes with the extraction tool. I have the drawings from the company and
can plot them in a .pdf file if anyone is interested. Perhaps, if Bob
doesn't already have them, I could send them to him for posting.
Cheers,
John Schroeder

This is the Bussman 15710 Series ATC Fuse Block, which includes the 15711, 15712
and 15713 (single, dual and triple bus versions).
The tool is for the Delphi Pack-Conn III terminals that are inserted into the fuse
block. The tool is probably more specific to the terminals than the fuse
block.

I might but I'm away from the main data base computer.
If you would be so kind to send what you have, I'll
make sure it either is or will be part of the data
archives on the website.

Does the Dynon have a serial port that can be configured to get EIS data?
I have an EIS4000 and a GRT Sport. The Sport can configure one of its serial input
as EIS input which drives the Sport's graphical engine page. The sensors
are connected only to the EIS4000. The Sport displays the exact same information
that the EIS does (only prettier :-) Of course GRT makes both products,
so this kind of integration is expected. Since the Dynon is a similar product,
hopefully they have a similar capability!

-------------------------------------
For redundancy and convenience, I want use both an EIS 4000 and a Dynon to display
engine data. Can I use the same sensor for both? How would I wire it to prevent
any crosstalk between the EIS and Dynon?
Thanks,
Brad

Worth a try, but not likely that the data streams are compatible.
It is possible to parallel sensors - depending on the type and what the
two devices do to energize the sensor. That said, it is not likely to
work with two systems that are specifically designed to work with
particular sensors.
For instance, the EIS-4000 has some straight voltage inputs and has some
inputs where it supplies current to the sensor. The VDO pressure
sensors are supplied current through a 470 ohm resistor in the
EIS-4000. If the line to the sensor were connected to a voltage input
on the Dynon, they would both function happily together. You would have
to figure out how to calibrate the Dynon in that case, but that could be
done by applying known pressures to the gauges. Same thing goes for
most of the temperature inputs (except the EGT and CHT) thermocouples.
In the case of temperature sensor, you would have to apply known
temperatures - boiling water, ice water, room temperature as compared
with a good thermometer.
The problem you will run into is when both the EIS-4000 and the Dynon
are supplying current to the same sensor - and looking at the specs it
seems like that is the norm. In that case, the only way to parallel
them would be to somehow disable the current drive in one of them. Of
course, if you do that and that instrument fails then you get no output
from that gauge.
I am actually doing the very thing you are trying to do. However, I
have an EIS-4000 and a BMA/EFIS One (I know, good news / bad news) that
has inputs that can be configured to provide sensor power or just accept
a voltage input.
