This is correct. Y1 Blue wire goes thru ecno plug and comes out Gray goes to #2 terminal on 1st CLO. Goes thru CLO to n/c contacts at terminal #3. Then leaves CLO on to HPS than LPS then #1 compressor contactor. Terminal #1 Brown is com. for CLO's & White is x terminal normally open and goes back to connection board. Y2 Yellow wire goes thru ecno plug and comes out Orange goes to #2 terminal on 2nd CLO. And repeats as above.
Question is how can it measure any compressor leg amps if the contactor has never engaged ?
Also if OP has 24 volts @ contactor it already made it thru all the hoops described above.
Now if the contactor engaged then disengaged because of no amp read i would look at the CLO.
Ever have a car with the lights working but when you try to start they dim ? You could read 12 volts @ the battery but have no cranking AMPS.
