I believe that the way this works is:
On my tractor, power comes in through a 10amp fuse to Defroster mode detection switch and the a/c switch
If foot/defrost or defrost is selected, power is bridged to acld and a/cs
If the a/c switch is enabled, power is bridged to acld and a/cs
If the THE or HP comes back with different values, the a/c is turned on or off depending on their values
The acmg output is what controls the a/c clutch
If I understand this correctly, based on the diode arrangement, it appears as if acld and a/cs are inputs, so I don't understand why you would need both of them? To me they appear to be doing the exact same thing? What would that resistor be there by the LED for?
Thanks for reading.
