Fan motor relays

Take a look @ The Pantera Place, tech. info. A/C Condenser Fan Relay Time Delay

Look at this page at Waytek. They have a lot of options for a delay-off relays.

I'm curious why is this desirable mod?

Here it is.

I can see it being helpful in taking the load off the start up sequence, Maybe having one on the AC too.

Exactly
RRS1, thank you. I think this one will work.
I might even wire my second fan through the temp switch with a delay off to allow run and cool down the rad after the ignition is switched off.

Take a look at Pantera Electronics:

Great system!

I agree with Indy Dave on this. If you find yourself needing to deal with the fan relays you are ready to upgrade them and forget about any additional grief.

Consider the P-E unit. It just makes the BS normally associated with the original setup go away, unless you like additional stress in your life?

So I'm planning on going PE, but its hard to do when you don't understand the current mess of wiring. :-) I have a wire that was tapped in to ignition wire near the fuse panel and went to one of the connecters to the relay panel (My fan relays are in passenger apt). The other side of the connector was a lt. blue wire that goes to the first(?) fan relay. Is that correct? Should that relay get power straight from ignition with no fuse? All the other fuse wires on 11 and 12 seem original. If it is supposed to be there, I probably won't tap it back in as I'll be moving the relays to the front with the kit.

No, you will no longer need or use the relays and relay wires with the P.E. fan controller.

You can read the instruction manual (just a few pages) on the P.E. website. It is a very easy install.

Correct.

Install the P-E unit first. Then you will be able to remove the added wiring.

You will see the light. You will become inlightened.

The only thing you will be upset with is yourself for not having installed the P-E earlier.

You are not condemed to an electronic Hell with the stock components. There is help.

Just follow the light!

LOL! I totally plan to install most of his stuff as my wiring is all stock. Going to go in the order he suggests. But, since it starts with the fuse block, I'm working on sorting that as best I can now.
There are just splices everywhere, I can sort of tell what is factory and what isn't, but just because it isn't factory doesn't mean its wrong...

Proceed as you like but I was in a similar situation and found that it was very efficient to identify the added wiring as each component was replaced.

By far the most difficult to do is the fuse panel. Sounds simple but it is not at all.

You need to maintain the polarity of the lines there. There are lines in and out, or power in and line load if you prefer to phrase it that way.

The stripes on the wires actually vary to identify this in the harness.

By the time I finished with all the components (except the a/c relay panel...that's fairly new and I haven't gotten to that) I removed maybe 20 pounds of additional wiring and relays that the combination of both I and the previous owner thought was genius to install.

Now you can actually trace a wire through the car and be able to read the wire colors correctly and know where they go.

For me the most important one to do was the ignition.

I could never make hide nor hare of the original with the ballast resistor and the Pantera Tach is very fussy and IS NOT a typical Ford designed instrument.

At one point I had installed an entire MSD system and no matter what adapter I used the tach just would not work.

It only works one way and with the P-E it works great.

You can also call Jon when you run into issues. If he didn't commit suicide after helping me, anyone else is a piece of cake for sure?

Interesting, thanks. I can see the merit in that. I was really attempting to get things to....normal before replacing componants thinking that would make it easier. I so still have a couple of wires to replace as I'm changing out things with, uh, wirenuts. It was all working prior to this work, but some of this I just have trouble with. And while I understand the functional drawings ok, I'm still learning.
I won't be doing the AC controller as my AC is shot and I'd like to get teh car running before I fix it. I do like that plate he has to mount everything tho, since I'll be moving to his components.

If you are pulling any new wires through the rocker panel, you might want to add one more wire that can be used as a pull wire for any future wiring to the rear of the car. If you ever decide to use Jon's A/C controller, you will need to add one more wire for the AC. This is due to the '71 cars having only one relay for the A/C, which means that there is only one wire that feeds the A/C compressor clutch and the condenser fan. Later cars have two relays and two wires to the rear...one for the compressor clutch, and one for the condenser fan. Jon's original design did not address this issue. Let's just say that I was instrumental in helping with the design.

We all need to pitch in when we can.

Well it's too late for that, but, I didn't have much issue using a fish tape to get a new coil wire through the rocker. I'm going to have to put in new ac lines, so I can pull that wire then.
