Electrical Tech / 22k ohm resistor Ignition wiring dark green / yellow wire from the ign coil
helped a guy out who watched my several parts series on youtube relating to bench testing your TFI's & PIP's off the car to verify your spares are actually good.

he was going through distributors a lot,, meaning over a few months bad again.  he's a fox stang 85 cfi.
we talked on the phone a lot and bounced around ideas then it appeared after he dragged his dad into all of it,, his dad being a dealer wrench (retired i guess) , started to focus on this good ole 22k ohm resistor.

my suggestions were not so helpful because to be honest ,, not many of us here ever talk about that red headed step child and i admitted i just dont have the subject matter experience to speak to where its at,, what it does or anything.  I fixed all that and i clearly understand now its purpose.  the fella got his 22kohm resistor installed and i suggested a 5watt min and also to paint on some liquid electrical tap all over the soldered areas and then get it in the wire loom.

to to my thougths,,,
in my EVTM,, for the 87 version,, the 22k ohm resistor shows up in the wiring diagrams on one of the DG/Y branches.
the CFI 3.8L shows this particular branch does not go back to the EEC pin 4 like the 5.0 and 2.3L does.  Now im confussed.
To  my best examination of the EVTM,, i do not see this resistor mentioned anywhere else except for the diagrams pertaining to ignition on the 5.0 & 2.3L only.  there is no reference as to its location as well.   the fella that i was helping told me he found his just a couple feet up the coil harness headed towards the firewall.  His was 100% open.
So those of you with knowledge about this resistor,, share your thoughts..  I get what it does now and its malfunction perfectly explains why many of us or you out there keep having to replace distributors,, and yes there are poor quality parts out there today but would'nt you like to eliminate this easy to repair part just for the sake of knowing you "know" its good and perhaps maybe the next dizzy you get might actually work correctly.

here is a great snipit from TMOSS that really explained it in better detail.
the short version is once the primary of your coil transfers energy out to the secondary,,, and then once that event is over,, the secondary will discharge some residual energy back onto the primary (which is not what we want),, ford "knew" that one branch of wire would lead up to pin 4 off the EEC.  That being said,, they installed what i would technically be able to refer to as a "strike absorber" like in a SPD or TVSS in the world of AC Power.  it basically absorbs the massive amount of energy headed towards pin 4 of the EEC and absorbs the hit and disipates the vast majority in the form of heat.. while the 22k ohm resistor will allow some safe level to reach pin 4 and do its job of monitoring spark triggers.

***my issue is,, what the heck is going on with the 3.8L??????  it seems to have no such animal and i just dont understand why.
furthermore why would the 2.3L and 5.0L have this in common being such different platforms...?

anyway,, here is some high level TMOS ramblings of the topic of the 22kohm resistor... Enjoy and reply if you have knowlege or thoughts on this,, i find it very interesting.

Lounge / free canadian coins
i have what i believe is totally uncirculated ( Provincial Flower and Coats of Arms )  set lacking one for which i have no need for. 
if anyone wants them then let me know.

I am missing Newfoundland

Description
From 1965 to 1968, Shell Canada has issued commemorative medals on Provincial flowers and coats of arms. These medals were given to customers for their purchase of gasoline.

Electrical Tech / fuse link info with vid link "how to test"
wanted.............

looking for a reliable resource that clearly states the oem intended ampacity for each color coded fuse link as it pertains to the automitive manuf industry.

example, the dual bn/or leads of the stock 5.0L output on the alternator leads up to a fuse link up to the starter relay stud shared by the battery cable.
what ampacity designation is this particular fuse link even though it could vary,, what is the engineering runway behind the choices of the fuse link wires and thier intended ability to handle variable current demands?

Engine Tech / harmonic blancer / damper came apart **SOLVED**
351 ford bronco 1990 full size

symptom- engine was shacking a bit like a plug wire was intermittent or maybe a misfire while under a load.  i also thought i had heard a metalic rattle under the hood. i checked the plug wires and all was good and tight.  i moved on to see how my fuel presure was and found good readings but................  then i heard a  rattle  while running similar to the one i heard when i was parking it last time a couple days ago.

the outter ring of my harmonic came off.

I keep equipment so long that it seems like i end up having to deal with problems that take years to surface like this one.  Ive never repaired a harmonic so any advice will be helpful.  What i need to know is are there factory alignment marks so when i install a new rubber,, i know i am doing it right.  Otherwise i suppose i could find TDC and dial it in like that especially knowiing my timning chain is really new.

i am not sure if we have harmonic "balancers" or "Damperrs" or a combo of both.  if both thaen that answers why i felt like the engine was running a tad rough.

thanks

Lounge / Speed of Air Pistons
We have a lot of good technical engineering minds here and i wanted to know your overall impression on the new Speed of Air pistons.
Real use data heafty data points lending itself to have earned the tag "New Piston Breakthrough",, just my opinion so far.

try not to focus on cost ,, many people do not know the two most expensive phases of a project are R&D as well as Customer Ownership.  everything in between when an item hist the market lowers the costs of either end when said item is no longer the new thing on the market.

Lounge / Help with what the proper naming convention is of my ESD/Soldering mat
Help with what the proper naming convention is of my ESD/Soldering mat

I have had an ESD/Soldering *HARD BOARD" mat in my garage since 95 when i got out of the Navy.
This was on my workbench at NAS Oceana for my entire time working micro-miniature component level repair in my avionics shop 69A.
close to the days i was a short timer, the shop was getting new ESD boards for all the soldering stations and we asked if we could have them and the shop supv said he didn't care, they were classifed as consumables.  I carried mine home and its been a real soldier at all the abuse you can imagine.  Time has finally taken its toll but its still functional and useful.... however,  I am in the market for another one to place on my newly fabricobbled dedicated electronics repair station.  I am looking on line and to my surprise, seems like everything i am finding for soldering workbench mats are all silicone.  Sounds inferior to me and not something that will stand up to my kind of standards and expectations of a proper soldering mat.

Here is a quick vid of what i have and i am looking for something like it.  My issue is i dont  know how to shop for it,, meaning i dont kno what its called believe it or not.  I am now starting to believe its BakLite with maybe a cermaic coating???  I dont know but i want to at least see if i can find another.  If anyone at all is familiar with soldering stations where there would be a hard board desk top mat and you know what they are called, chime in.  This one in my vid was also an ESD mat but its almost indistructable.

thanks in advance for any ideas or networking me with someone who may know.

Lounge / AC Power grimlin
if your power savey,  help me figure out what the heck is going on here in this vid i uploaded yesterday.

I have no idea what to check next  likely because i dont think i have a tool required to check my branch circuit feeding my garage.

This is a real mystery

T-Bird/Cougar Parts & Cars WANTED / Wanted- Oil Pan for 5.0L
I am experimenting on doing a two piece oil pan and would like to also post the process on my youtube channel " I FIX IT ALL".

A two piece pan would allow one to remove the pan without too much trouble,, pull the two long bolts out for motor mount then jack up the engine a little bit to achieve bell housing and front rack clearance.

location is 24941 and ph 304 772 4082 ask for scott.

Electrical Tech / EEC / computer power relay relocation
I  was really disappointed in how ford mounted the computer power relay.  Its location being difficult to get to is an understatement.
I am considering lowering it downward and over to an area that would put it basically behind the glove box.

meaning,, you open said glove box then push in the tab of the clove box so it swings completely down.  now when you look at your hvac enclosure, to the right there would reside the power relay.

thoughts?

tid bit of random knowledge her in case anyone out there needs to know...............................................
*** IF *** you have a ford engine with a CFI fuel injection system.... your EEC power relay is unique unto itself.  it is not by any stretch a mirror of what you would know of as a standard relay.   more specifically, if your engine has an IDLE SPEED Control Motor, mounted to the side of your CFI,  the proper relay for your car would be one that has a time delay built into the low current side / coil side of the relay offering a time delay when you turn your ign sw "OFF".  during power down, the eec power relay stays energizd for a couple seconds to respot / re-position the nose of the ISC motor for your next startup.  once this eec command is complete, the eec power relay will power down.,,, actually after a couple seconds it will power down.  All im saying here is that the eec power relay has a power down time delay built into it just for the sake of properly operating the ISC motor controller.

I swapped in a 5.0L sefi into an originally built 3.8L CFI coug, i was able to use a standard relay for this application and so would anyone else who *does not* have an ISC motor controller typically only equipped on CFI application engines by ford.

Suspension/Steering / quad shock OEM parts on rock auto
once upon a time, i had to replace the OEM horizontal shock in the rear of the 20th and had a hell of a time trying to find them in box stores.  I ended up measuring the lenth and bought a set that seemed to be called out for Jeep.

later on i was drilling deep into Rock Auto and as with any life lesson,,,, if only you knew what the  thing is called you might be able to find the part.

i sumbled across what appeared to be an identical looking ""cone"ish ended looking shock that rock auto had at that time dub'd as a "steering dampener".  I lookded at the specs and it was a match for these two tiny shocks and ordered a set , stored them back and later on installed them.  I called rock auto and had them update how they classified these shocks so people can find them easier and now they can be found under the following path............
car info.../ drivetrain / axle shaft dampener 

just fyi incase you too were wanting something that looked identical to the ford OEM ones.  they are 24$ ea by Gabriel pn 14039
