Gus, and group, When the low pressure switch is closed as David said, the 
voltage will go to the fans wheather the compressor comes on or not as long 
as the ground thru the compressor is there and the diode isn't blown and the 
relay is good and the fan voltage is there from the brown wire. If the low 
pressure switch opens, then the voltage goes away to the The Fan Fix relay 
coil , then there goes The Fan Fail that is in line with the fans. Now, If 
the water temp switches opens or closes, that two will turn the fans on and 
off. The fans will respond to commands from both of the circuits too open or 
close or do both at the same time. Page 232 & 233 of the tech book. On page 
241 of the tech book, it shows two switches. My air man said it was a high 
and a low pressure.. Who knows.
