CHT readings


Recommended Posts

Both CHT wires go from the sender to the 37 pin connector on the D120. I know the left side is pin 4 and can't remember which pin the right CHT is. It is in the Dynon installation manual.

\If you have no disconnected the #2 yellow wire called the "Keep Alive " wire from the 37 pin connector that absolutely needs to be done first. I would open up the 37 pin connector and look at both wires. Another thing you can do is use a jumper wire and switch probe sides and see if the problem follows the switching or stays on the same side.


I just did all this today and found a broken wire from the #4 connector with the 1.2K resistor had broken inside the 37 pin connector..
