Another problem with the electric cooling fan is that the refrigerant temperature switch seems to be ineffective. It would be better if the electric fan ran any time that the A/C compressor was operating. One way to accomplish this would be to install a heavy-duty in-line relay, triggered by the A/C compressor signal, to operate both the compressor clutch and the cooling fan. A diode should be used at the fan, to prevent triggering the compressor when the temperature switches operate the fan.
************************************************
However Just How is the best way to do this ?
Let's see it says install a
(1) in line triggered Relay Question ? What sort of relay would that be ?
(1a.) just what size wire and from where should I run it to this relay ?
(2) Triggered by the AC Compressor signal . Question that's the Hot wire to the Compressor yes ? But that wire ? does it trigger also the cooling fan ?
(3) Now this Diode ? Question what sort of Diode ? Type ? / Model / Link to Part ?
(3a) is this correct in a 1980 Model YR ? the signal wire to the AC / Idle control Signal also signals the Cooling Fan ?
I thought the Cooling Fan was controlled by some Temperature Control . The Guy Mentions this
"prevent triggering the compressor when the temperature switches operate the fan."
Alan any Directions you can give to set this up would be great .
I Understand the Diode Idea But have no Idea what sort of Diode they are talking
Now the Relay Just what sort of Relay would be good for this ? Not familiar with a In Line Relay Types
So This Diode allows the Power signal to go to the Fan but Not back from the Fan ? or do I have this all wrong ?
