[DeTomaso] fan question

[Christopher Kimball]

Thanks, Forest. But I want to try and avoid cutting into the relay wires or having to run a whole new set of wires or even one wire, to the relay. Also, if I can do what I'm hoping by just adding 12v to the A/C input on the DD box, eventually I can buy another dakota digital box that works and just replace the one that's there now, without having to run new wires everywhere. Sincerely,  Chris

Chris,
Which digital fan control model do you have? If you just want this fan to run whenever the ignition is on you can just run the switched 12 volt wire directly to the fan relay and not even use the fan controller. If you want something else to happen then let me know and I can help you out.

  Hi everyone,

  Today Doug, Mike, and Brian from PNW came over and assisted me in the
  installation of my new thermostat, and when I say "assisted me" what I
  mean is they did all the work and I watched...:). I really appreciate
  their help.  There was an interesting snag we hit when it turned out
  the rear bolt holding the thermostat cover couldn't be removed because
  part of the Edelbrock flange extended too far over the bolt's head to
  enable the bolt to be extracted.  We had to use a hacksaw to literally
  cut away some of the aluminum so we could remove the bolt to get the
  cover off the thermostat.  I took a number of pictures and will write
  an article about it sometime soon for possible inclusion in one of the
  POCA publications, perhaps.

  Thanks to all of you on the forum for all your assistance in getting
  the correct components for the thermostat project, but here's another,
  weird "Pandora" twist:  It turned out the gasket I got from summit--the
  expensive deluxe version--was the wrong gasket in the right packaging!
    The difference was subtle, but once we started installing the new
  thermostat and gasket, I noticed one edge of the gasket sticking out
  further than I thought it should.  We removed it and compared it with
  the gasket Mike brought (it was extremely fortunate he thought to bring
  it) and they were slightly different despite the fact the one Mike
  brought was in identical packaging to the one I got from Summit!  Word
  to the wise--don't believe everything you read on a package, and always
  double-check everything.

  Here's my latest question:  I discovered my Dakota Digital fan system
  is not working correctly, although it sort of works.  What I'd like to
  try is to see if I can get the unit to send out the correct signal to
  the fan relay to turn on the fan (this system is used only for a third,
  sucker fan I added years ago).  What I'm considering doing is taking a
  12v line which is ignition-switched, and running it to the "A/C input"
  on the Dakota Digital box.  That input is designed to get a 12v trigger
  signal from the A/C unit which then turns on the fan whenever the A/C
  system is operating.  By running 12v to this input when the ignition is
  turned on, I think I should be able to have the DD box send the correct
  signal to the fan relay since the box will read the 12v from the
  switched wire and think it's 12v coming from the A/C system.  This way
  whenever the car is switched on the third fan will run.

  Do you think this will work, or is the 12v coming from the A/C (the
  "A/C trigger") different than just a straight 12v coming from an
  ignition-switched source?

  Thanks again for all your help!

  Sincerely,

  Chris
