Another task done today was completion of the wiring for the CO Monitor. After a two-month wait, I finally received word from Guardian Avionics regarding how to wire the 353D-x01 model carbon monoxide monitor. Aparently it's nothing like the drawings they send!
Long story short, and despite what the drawings show, the CO monitor does not have RS232 serial comms capability, nor does it have an audio signal output at pin 6. Pin 6 is actually a 0-5V output for sending CO level data to a spare analog input on the Skyview EMS.
This revelation required some rewiring!
While cutting away cable ties from my wiring loom I discovered a nick in one of the fuel tank level sender wires, so I carried out some running repairs (see picture below).
The red heatshrink is testamant to running repairs!
