I know how to eliminate ALL 3 relays!

One other major problem your circuit has, the temp sensor will supply the current for the AC compressor clutch winding. It is not designed for that much current.

Both low and high speed windings can be powered together with this circuit, if the manual switch is in the high speed position......

The way your circuit is done, tha AC will not turn the fan on unless you have the switch set to give power to the low speed relay (through the temp sensor). This is not a good design, which I've previoulsy told you about!

Connect the diode like I suggested!!!!!!! If the switch is set to manual HIGH, the relay for the low speed will never pick!! If the fan is working properly, the temp switch shouldn't close while the high speed is running.....

Your circuit is wrong. Eliminate the AC relay, and place a diode like this, and the fan will come on high whenever the AC is on, they way it should have been done in the first place:I told you about this problem in this thread (post #17) in 10/2/07...

The AC compressor relay is going to pick along with the low speed relay, so I would expect the AC compressor to run when the fan comes on low speed. The circuit needs to be changed so whenever the AC compressor gets power, the fan will come on. Right now, the fan turning on low speed causes the...

Have a great trip! We lived in Germany for 7 years while growing up, my dad was in the Army.Nikon just anounced a new DSLR camera, the D3000, which will replace the D40.....too bad you aren't taking that with you!

I've got these Marchal's in my Volvo 1800E. They are excellent!http://www.panteraplace.com/page157.htm

Happy birthday Lester!!!

It's a waste! The WOT voltage is determined by the idle TPS voltage any way. If the idle TPS voltage is set correctly, there will be no advantage.

I turned 150K on my Ranger in March '08:She has 171K now.

+1 If you make the intake too large, you won't get any more airflow, but the velocity of the air goes way down.

Ford has issued a TSB NOT to use mutli-purpose (Merc/Dex) ATFs!!!I'm sure Vince or Dave can quote the number on it!!

Merc/Dex multi-purpose ATFs is totally different than Mercon or Mercon V.

You can use Mercon V in Mercon applications, but you you can't use Mercon in Mercon V applications.......Matter of fact Ford no longer markets Mercon, only Mercon V.

I'll try and stop by with my camera and get some interior shots while they are open....

If you leave the old on in place, put a little oil in it, and run a hose from the output port to the input port. This will keep the valves in it from going bad, just incase it is needed later.

Anybody ever heard of an Amarillo F-350?

We all have our moments......

A larger pulley on the supercharger will slow it down....

My bad, I thought you were talking about an underdrive pulley kit.

A SMALLER crank pulley will spin the accessories slower, NOT a BIGGER one.

Here are some Challenger photos for you Brad:

The AC compressor isn't cut off with WOT?

She will be in my prayers Ian!

Changing the dryer is a good idea, the desiccant bag may have ruptured.

Of course this will be true for closed loop, and until the fuel tables are changed by "adaptive control" for open loop.

I think what Paul meant was the PCM will reduce the injector pulse width to keep the A/F the same with the increased fuel pressure.

Unless you increase displacement, or go to forced induction, larger injectors will just cause problems.
