Thanks guys now we are getting some where.
Rusty the ECU I refer to were the very early production 70 to73. Sometime in late 73 the battery acces cover was removed and the ecu was sealed at least the ones I remember. Great info as well. The9v battery minder I haven't used since 1990 LOL they only worked for a few hours and were mainly for keeping your clock alive and your radio programed with your station selections IIRC.
04bradford thank you that confirms and clarifies what I suspected Kam to be a working memory buffer. However on the systems I have worked on that had the KAM problem. I checked wireing suspecting that as a possible culprit many times. I came to the conclusion that it may be internal to the PCM itself. #40 has always had stabil power when tested at the plug.
Yahiko great info as useuall. What else can I say other than you wana help me find my hacker??? LOL
Thank you all keep them comeing
SHHH! I see Nothing.
Add to that I know Nothing.
Best said by.
Nuff said lol. If I was not so determined to actually find him. I would just ignor him/her.
What I have been finding looks more like a script kiddie than a master hacker.

They endless abound. or should that be they abound endlessly.
Yep I like the 2nd one.
That may have been something I posted LOL I used to change the batteries often in the old days. There was a cover on the ecu, battery and fuse were underneath.
I may as well let this die and slide off the board. Until someone opens up a PCM we may never know. No diagrams that I can find online.
Restlesswildman I did find some pictuers but not much help they only show one side of the ecu. The cover does have 4 small screws so maybe I was confuseing what I remember. It was a long time ago and my memory ain't so good sometimes.
Funny thing I went to the tool box to pick out a torx driver.
I grabbed the right one first try.
Easy opening job and after the bit I thought it would be a pain to open.
Dark stain was the buffer pad.
No battery in sight. Just the programming port and some
crystal oscillators.
Thank you for that. I really did not exspect to find an actual battery in a PCM but more like a capictor array or something that would be recogniseable as power.
No such luck from what I see in the pics.
Well back to the drawing board. LOL Hey at least the last document confirms that the kapwr circuit is the pwr circuit for a 6.0 pcm.
Well last night while researching I came across a document that makes me question my own memory. It said Ford did not come out with an ECU untill 1980.
Maybe too much canibis during that time frame LOL who knows now.
