....if she thinks it's 'rising' at 1:30 AM, I'd go back inside....

Hey, Jamie... I went outside and looked at that harness... Is the diode in the small, like 1 foot- 1 1/2 foot harness from under the coil shield to the clutch itself??? Also, how do I test it, and where the hell is it? lol

You need to look at the one about 6 inches from the IAC on the IAC wiring to see what you are after. It's a little roll of life savers looking thing wrapped up with tape. The short harness to the AC coil should unplug from the main harness and you can use some paper clips to insert into the plugs to check it out.

Ok, so if they are bad... what do I do? Can I buy a replacement harness? The small one? Or do I have to replace the diode(s)? Or am I stuck with junk yard parts?

Junk yard part from any EFI car will give you what you need.

 

[Stang8URMPRT]

Any EFI car? Or any EFI Mustang? Or any EFI Ford car from the same year??? Try to narrow down which I can get it from.

Thanks man for all the patients.

Pretty much any dang thing with that style AC coil on a V8. T-birds usually have to complete harness, not sure about Crown Vics.

I looked at the Mustang wiring diagrams and the diode assembly is wired parallel to the cluctch coil assemby. One leg connects to the clutch power and the other connects to the clutch ground.

The diode is wired reverse, cathode to power & andoe to ground. This clamps any reverse spikes that might damage the computer. See the attached thumbnail drawing for connection details.

If the diode fails, the clutch will still operate. You have another problem not yet discovered. Start checking the wiring for volage drops.

See http://www.fluke.com/application_notes/automotive/circuit.asp?AGID=1&SID=103#volt for help troubleshooting voltage drops across wiring and connections.

Hey, Jrichker... I live in Florida.. I'll just drive over and PAY you to fix this crap. lol. There is one thing I have never learned, and never want to.. and that's A/C.

So far all your problems are electrical. Keep looking & re-post or PM me.
