Actually, I like the magic of number 4 more. It brings more peace to my life. You can read this as an example - https://www.sunsigns.org/angel-number-44-meaning/ Have you ever tried to pay attention to the numbers in the problem report? It can also say a lot .. Although I agree that it looks like superstition to many ..

So, washers on # 1 and #4 ?? I believe they belong on #2 and #7. Sounds
like other issues going on with the wiring as well.

1&4 is the way it was when I bought it. My bad for assuming they were
correct. So what you're saying is 2&7 are the hottest cylinders with 2
going to the front gage and 7 to the rear gage? Anyone else have their
temp probes connected to different cylinders?

Good Morning Greg
I fly a CJ with an M14P and my CHT sensors are on 1&2, not sure which is
front and which is rear. Not sure how the CJ comes from the factory with a
Housai. Or how a Yak with an M14P is wired either.
If you go to Dougs website and go to volume 5 and right click that book and
open it up in a different tab or download it to your computer look at page
407, Figure 2-14-2 in the book. It shows the complete wiring from the
copper ring to the plug that plugs into your gauge. Yes there are two
separate unrelated wire runs for the front and rear cockpits. Two each of
the assembly on page 407.
The sensor is a thermocouple and does not require any exterior voltage to
work. That is why it shows a cylinder head temp on the ground in the
hangar with the master off.
>From what I can tell, those of us that have the auto plug conversion kits
on our planes remove the washer on the spark plug and of course install the
thermocouple copper ring in its place. Hopefully ensuring proper
penetration into the cylinder head for good combustion.
You don't have to remove the washer on the plug, but I understand some
folks do.
If you take a look at page 407 you can see there are two separate areas
that have terminations that may be causing your shaking issues due to
possible loose connections or broken wires. On my aircraft I do not have
the intermediate terminals closest to the plug shown on page 407. The
thermocouple attaches at the engine and runs straight to the plug on the
rear of my CHT gauge. Not sure all planes are or were wired per the book
on page 407. The thermocouple assembly under the cowl is the first set
of screw terminals shown on page 407.
Hope this helps. Please let us know what you found. It may help others.

I can confirm that #1 and #4 rear spark plugs are the correct location for
the CHT sensors.
These are the two hottest cylinders. There is manual information that iden
tifies those and to which cockpit but I have no time right now to dig it up

Walt.
I am at the hangar with the tech manual for the Housai.
You are correct as usual. It is cylinders 1 and 4.
And Cylinder 4 goes to the front cockpit.
I have attached a photo of the page in the manual.
Start reading at code 41Y. 42Y talks about front cockpit. #4 cylinder.
Thanks Walt

Ok. At least I got everything connected to to the correct cylinders. 1&4.
Now just following wire or swapping gages (rear to Front) to see if the

We have this cleared up for the Housai.
Is it the same for M14P. Cylinders 1 and 4. Number 4 for the front
cockpit ?
