Tim and any others who have installed Cheltons, can you tell me the wiring lengths from the PFD to GADAHRS, OAT Probe, MSU, etc.?  

   

Thanks.

The answer to this is it would depend, based on where you  choose to install them, my GADHRS is only a couple of feet from the displays and  Tim's are behind his baggage bulkhead.

 I think Stein would be better to ask on this as he probably  has a default trim to length he makes for his harness

Read with a humorous intent, but Jesse, you should know better than

that!  Like Dan said...it all just depends on where you mount

Everything.  You can mount the GADAHRS behind the panel or in the

tail, you can mount the MSU (magnetometer) in the wing or in the

tail or any other magnetically ideal spot.  The OAT can go where

you want it (I prefer near a wing access panel at least 3 or 4' outboard

from the root.  So, you need to determine where you want the components.

The good news is, it's just shielded pairs and triplets so there's

nothing too fancy about the wiring.  I don't think there is any

"standard" harness to be had.

Read with a humorous intent, but Tim, you should know better than that!  I

didn't mean what is the standard because I know there is no standard, but

for those who have done it, where did you mount your stuff and how long were

the wires you used?  If I can get some ideas of where things were installed,

then I could measure for wiring runs, but if you also know your lengths,

that would help too.



Thanks.

I don't have any specific wire lengths because I pretty much

just pulled a piece of string-trimmer line from a grass trimmer,

cut to slightly excess length, and then pulled that out to use

as a length template.  Then re-pulled the bundle, with the

string trimmer length to use as a future puller.  So lengths

I don't have.  But, what I do have is an install write-up.

http://www.myrv10.com/N104CD/upgrades/20060531/index.html



I went with the tail installation because behind the panel

I just don't want to take up more room, and I think it's

got to be a pretty electrically noisy place already.  So the

AHRS is behind the baggage wall on a shelf.  The MSU I could

have put in the wing, which is great if you put it away from

the servos and stuff, but when I put mine in, I figured

it would be easier to wire the MSU to the GADAHRS if they

were somewhat close, and the further aft area of the tail

has worked well magnetically and electrically.  It's pretty

cool how when you calibrate the AHRS you can see to extreme

detail the magnetics with all the various live data that

is provided on the diagnostics screen. (This is the

pinpoint, of course)  so for me, the majority of wire was

panel to tail, and then OAT was wing to tail.  I doubt

you'd find a problem with mounting the MSU in the wing.

The hardest part might be getting everything level...but the

calibration procedure actually allows you to calibrate out

mis-leveling fore and aft too.



Sorry I don't have specific lengths.

I have my AHRS mounted on rails directly behind the baggage bulkhead.  My wires run up the right side of the aircraft behind the baggage compartment cover. I have the Crossbow and therefore don't have to worry about the magnatometer.  My OAT is in the bottom left wing root cover.  



I just pulled a bunch of wire that was too long when I did it.  I also pulled enough wire for the PinPoint upgrade but that didn't happen for me.  



After watching this past weeks episode of "The Office", I'm starting to worry about all this high end Chelton type technology.  If Michael Scott won't trust it, who can? (I realize only a few will understand that one, I've become a big fan)
